Press E to exit the setting screen. • Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night).
Time Calibration Signal Reception There are two different methods you can use to receive the time calibration signal: auto receive and manual receive. • Auto Receive With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive” (page E-20).
Important! • When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. Make sure there are no metal objects nearby. 12 o’clock or • Make sure the watch is facing the right way.
• Proper signal reception can be difficult or even impossible under the conditions listed below. Inside or among buildings Inside a vehicle Near household appliances, office equipment, or a mobile phone Near a construction site, airport, or other sources of electrical noise Near hightension power lines Among or behind mountains • Signal reception normally is better at night than during the day.
• The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below. Home City Code LON, PAR, BER, ATH TYO, SEL NYC, CHI, DEN, LAX E-18 Transmitter Anthorn (England) Mainflingen (Germany) Fukushima (Japan) Fukuoka/Saga (Japan) Fort Collins, Colorado (the United States) Frequency 60.0 kHz 77.5 kHz 40.0 kHz 60.0 kHz 60.

Note • When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings. • Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
About the Receiving Indicator The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest. The receiving indicator is displayed while an auto or manual receive operation is in progress.
• Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations. • Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 5 receiving indicator will remain on the display in all modes. The Level 5 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

Digital Compass A built-in bearing sensor detects magnetic north and indicates one of 16 directions on the display. Direction readings are performed in the Digital Compass Mode. You can store a direction reading in Bearing Memory and display that reading as you take subsequent readings. • For more information about Bearing Memory, see page E-46. • You can calibrate the bearing sensor (page E-39) if you suspect the direction reading is incorrect.
To enter and exit the Digital Compass Mode 1. While in the Timekeeping Mode or in any of the other sensor modes, press C to enter the Digital Compass Mode. • At this time, the watch will start a Digital Compass operation. After about two seconds, letters appear on the display to indicate the direction that the 12 o’clock position of the watch is pointing. • The direction reading on the display is updated each second for up to 20 seconds, Current time after which measurement stops automatically. 2.

While the watch is in the Digital Compass Mode, place it on a flat surface, or if you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon). 2. Point the 12 o’clock position of the watch in the direction you want to measure. 3.
• While the watch is taking compass readings, it displays a direction angle, a direction indicator, and four direction pointers, which change dynamically when the watch is moved. The direction angle, direction indicator and direction pointers all disappear from the display after the compass reading operation is complete. Note • Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in large measurement error.
• The following table shows the meanings of each of the direction abbreviations that appear on the display.
Digital Compass Precautions This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia.
• Accurate direction readings are impossible while in a train, boat, air plane, etc. • Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc. Storage • The precision of the bearing sensor may deteriorate if the watch becomes magnetized.
Calibrating the Bearing Sensor You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. There are three different calibration methods available: magnetic declination correction, bidirectional calibration, and northerly calibration. • Magnetic Declination Correction With magnetic declination correction, you input a magnetic declination angle (difference between magnetic north and true north), which allows the watch to indicate true north.
• Bidirectional Calibration and Northerly Calibration Bidirectional calibration and northerly calibration calibrate the accuracy of the direction sensor in relation to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason.
To perform magnetic declination correction 1. In the Digital Compass Mode, hold down E for about two seconds until the magnetic declination angle value starts to flash. This is the setting screen. 2. Use A (+) and C (–) to change the magnetic declination angle value. lll ll 3. Press D to move the flashing to the magnetic declination correction direction setting (OFF, E, W). • This will cause the magnetic declination angle direction setting to flash. Magnetic declination 4.
• The illustration on page E-41, for example, shows the value you should input and the direction setting you should select when the map shows a magnetic declination of 1° West. 5. When the setting is the way you want, press E to exit the setting screen. • Selecting OFF for the magnetic declination angle direction causes the watch’s magnetic declination angle value to change to xx. Precautions about bidirectional calibration • You can use any two opposing directions for bidirectional calibration.
To perform bidirectional calibration llll lll lll lllll 1. In the Digital Compass Mode, hold down E for about two seconds until the magnetic declination angle value starts to flash. This is the setting screen. 2. Press D twice to display the bidirectional calibration screen. • At this time, the north pointer flashes at the 12 o’clock position to indicate that the watch is ready to calibrate the first direction. 3.
• xxx is shown on the display while calibration is being performed. When calibration is successful, the display will show OK and the Digital Compass Mode (showing the angle value) screen. • If xxx appears and then changes to ERR (error) on the calibration screen, it means that there is something wrong with the sensor. When ERR disappears after about one second, try performing the calibration again.
3. Place the watch on a level surface, and position it so that its 12 o’clock position points north (as measured with another compass). 4. Press C to start the calibration operation. • --- is shown on the display while calibration is being performed. When calibration is successful, the display will show OK and the Digital Compass Mode (with 0° shown as the angle value). • If --- appears and then changes to ERR (error) on the calibration screen, it means that there is something wrong with the sensor.
Bearing Memory Bearing Memory indicator Bearing Memory lets you store a direction reading and display that reading as you take subsequent readings. Bearing Memory direction angle The Bearing Memory screen displays the 12 o’clock direction angle for the stored direction, along with position an indicator in the ring around the display that also indicates the stored direction.
2. While direction angle readings are in progress, press E. • This will cause the direction angle to flash for about one second as it is stored in Bearing Memory, and then the Bearing Memory screen will appear. • While the Bearing Memory screen is on the display, you can press C to start a 20-second direction reading operation that displays the direction angle for the direction that the 12 o’clock position of the watch is pointed.
Using the Digital Compass While Mountain Climbing or Hiking This section provides three practical applications for using the watch’s built-in digital compass. • Setting a map and finding your current location Having an idea of your current location is important when mountain climbing or hiking. To do this, you need to “set the map”, which means to align the map so the directions indicated on it are aligned with the actual directions of your location.
To set a map and find your current location North indicated on the map Current location N N North indicated by north pointer 1. With the watch on your wrist, position it so the face is horizontal. 2. In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading. • The reading will appear on the display after about two seconds. 3.
To find the bearing to an objective N N E-50 1. Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location. • See “To set a map and find your current location” on page E-49 for information about how to perform the above step. Objective 2. Set the map so the direction you want to travel on the map is pointed straight in front of you. Current 3. With the watch on your wrist, position it so the location face is horizontal. 4.
• This will position the map in accordance with your current location, so the bearing to your objective is straight ahead of you. To determine the direction angle to an objective on a map and head in that direction N Objective Current location N 12 o’clock position 1. Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location.
• If you find it difficult to perform the above step while keeping everything aligned, first move into the correct position (12 o’clock position of the watch pointed at the objective) without worrying about the orientation of the map. Next, perform step 1 again to set the map. 3. In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading. 12 o’clock • The reading will appear on the display after position about two seconds.
4. After setting the map, keep the map and watch pointed in the same direction as you press E to record the currently displayed direction in Bearing Memory. • See “Bearing Memory” (page E-46) for more information. 5. Now you can advance while monitoring the indicator (indicating the direction stored in Bearing Memory) to ensure that it remains in the 12 o’clock position. Note • When mountain climbing or hiking, conditions or geographic contours may make it impossible for you to advance in a straight line.
Barometer/Thermometer This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature. • You can calibrate the pressure sensor and the temperature sensor (page E-136) if you suspect that readings are incorrect.
• The displayed barometric pressure value changes to xxxx hPa if a measured barometric pressure falls outside the range of 260 hPa to 1100 hPa. The barometric pressure value will reappear as soon as the measured barometric pressure is within the allowable range. • Temperature is displayed in units of 0.1°C. • The displayed temperature value changes to xxx °C if a measured temperature falls outside the range of –10.0°C to 60.0°C.
Barometric Pressure Graph Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. This watch takes barometric pressure measurements automatically every two hours (at the top of each even-numbered hour), regardless of its current mode. Measurement results are used to produce barometric pressure graph and barometric pressure differential pointer readings.
A rising graph generally means improving weather. A falling graph generally means deteriorating weather. Note that if there are sudden changes in weather or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize. The following conditions cause the barometric pressure Not visible on the display.
Barometric Pressure Differential Pointer This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph (page E-56), and the current barometric pressure value displayed in the Barometer/Thermometer Mode (page E-54). • Pressure differential is indicated in the range of ±5 hPa, in 1-hPa units.
Barometric pressure differential hPa values Current pressure greater than most recent measured pressure Current pressure less than most recent measured pressure E-59
About Barometric and Temperature Measurements • Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, barometric pressure and temperature measurements are taken every five seconds. • You also can perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer/Thermometer Mode.
Altimeter The watch’s altimeter uses a pressure sensor to detect current air pressure, which is then used to estimate the current altitude based on ISA (International Standard Atmosphere) preset values. You also can specify a reference altitude, which the watch will use to calculate your current altitude based on the value you specify. Altimeter functions also include storage of measurement data in memory. You also can measure the altitude differential (change) from a specific reference altitude.
• To avoid the effect of sudden temperature changes during measurement, keep the watch on your wrist in direct contact with your skin. • Do not rely upon this watch for altitude measurements or perform button operations while sky diving, hang gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other activity where there is the chance of sudden altitude changes.
When you measure altitude using a reference altitude specified by you After you specify a reference altitude, the watch uses that value to convert the current measured barometric pressure value to altitude. • When mountain climbing, you can set the reference value in accordance with a marker B along the way or altitude information from a map. After that, the altitude readings A 400 produced by the watch will be more accurate than they would without a reference altitude.
The Altimeter Mode gives you a choice of four different display formats (page E-68). The format you choose determines what type of data is displayed. The Altimeter Mode screen can show any three of the following four items: altitude graph, altitude value, altitude differential, and the current time. You also can select either of the following two altitude measurement types.
To display your current altitude Current altitude Altitude graph Current time Altitude differential pointer 1. Press A in the Timekeeping Mode or in any of the other sensor modes to enter the Altimeter Mode. • The watch will start altitude measurement automatically, and display the result. • It can take up to four or five seconds for the altitude reading to appear after you enter the Altimeter Mode. 2.
Notes • Normally, displayed altitude values are based on the watch’s preset conversion values. You also can specify a reference altitude, if you want. See “Specifying a Reference Altitude” (page E-76). • Altitude is displayed in units of 5 meters. • The measurement range for altitude is –700 to 10,000 meters. • The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions.

Saving Altitude Data An altitude data save operation saves data in three different records: periodic records (page E-71), a current session record (page E-72), and a historical record (page E-75). To start a new save session llll llll l lll lll 1. Press A to enter the Altimeter Mode (page E-11). 2. Hold down A for about one second until REC flashes on the display, which indicates that a new session is in progress.
• Once you start a save session, measurement continues to be performed, and the REC indicator flashes on the display, even if you change to another mode. 3. To stop an ongoing save session, hold down A for about one second until REC disappears from the screen. • The save session also will stop automatically when Periodic Record 40 is stored. • The watch updates the historical record continually while an altitude measurement operation is in progress. See “Historical Record” on page E-75 for more information.
How periodic records are created and saved Note The following operation is performed simultaneously with the operation described under “How current session record data is updated” (page E-73). a. The watch creates Periodic Record 1 when you start a new save session (page E-70). Periodic Record 1 contains the current date (month and day), time, and altitude. • Each periodic record contains the current date (month and day), time, and altitude. b.
Data High Altitude (MAX) Low Altitude (MIN) Total Ascent (ASC) Total Descent (DSC) Description Highest altitude reached during the current session. Lowest altitude reached during the current session. Total cumulative ascent during the current session. Total cumulative descent during the current session. • The maximum total ascent and total descent value is 99,995 meters. Each value reverts to zero after the maximum is reached.
a. When you hold down A to start a save session (page E-70), the watch will clear data that is already stored in the current session record. b. The watch will measure altitude and calculate data as described below, and update the current session record accordingly. Note that measurement and saves depend on whether or not the watch is in the Altimeter Mode.
Historical Record The Historical Record keeps track of high altitude, low altitude, total ascent, and total descent values across multiple save sessions. The contents of this record are updated continually while an altitude measurement operation is in progress. How the historical record is updated The watch performs the following operations continually while an altitude measurement is in progress.
• See “Clearing the Historical Record” (page E-88) for information about clearing the historical record, which restarts all data values from zero. Other Altimeter Mode Features This section explains other features and settings that are available in the Altimeter Mode. Note that all of the information in this section applies to all types of Altimeter Mode measurements, unless specifically indicated otherwise.
To set a reference altitude llll llll lllllll 1. In the Altimeter Mode, hold down E for about two seconds until either OFF or the current reference altitude value starts to flash. This is the setting screen. 2. Press A (+) or C (–) to change the current reference altitude value by 5 meters. • You can set the reference altitude within the range of –10,000 to 10,000 meters.
Altitude graph Altitude Time The altitude graph shows Altimeter Mode measurement results. • The vertical axis of the graph represents altitude, and each dot stands for 10 meters. • The horizontal axis represents time, and the flashing dot in the rightmost column indicates the latest measurement result. For the first three minutes, each dot represents five seconds. After that, each dot represents two minutes.
Altitude Differential You also can use the Altimeter Mode to measure the altitude differential from a specific reference altitude. Specifying the point is as simple as pressing a single button to reset the current reference altitude value to zero. Altitude differential measurement is performed each time the watch performs an altitude measurement. • You must perform altitude differential measurement whenever you select format number 3 or 4 as the Altimeter Mode display format.
To reset the altitude differential value to zero Altitude differential In the Altimeter Mode, press E. • This will start altitude measurement. The altitude differential value will show 0 after measurement is complete. • You must perform altitude differential measurement whenever you select format number 3 or 4 as the Altimeter Mode display format (page E-68).

Illumination Auto light switch on indicator The display of the watch is illuminated using an EL (electro-luminescent) panel for easy reading in the dark. The watch’s auto light switch turns on illumination automatically when you angle the watch towards your face. • The auto light switch must be turned on (indicated by the auto light switch on indicator) for it to operate. • See “Illumination Precautions” (page E-134) for other important information about using illumination.
• Illumination is disabled during time calibration signal reception, while configuring sensor measurement mode settings, and during bearing sensor calibration. About the Auto Light Switch Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode. Note that this watch features a “Full Auto EL Light”, so the auto light switch operates only when available light is below a certain level.
Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on. • Wear the watch on the outside of your wrist. Parallel to ground More than 40° Warning! • Always make sure you are in a safe place whenever you are reading the display of the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury.
• When you are wearing the watch, make sure that its auto light switch is turned off before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury. To turn the auto light switch on and off In the Timekeeping Mode, hold down L for about three seconds to toggle the auto light switch on (A.EL displayed) and off (A.EL not displayed).
Questions & Answers Question: What causes incorrect direction readings? Answer: • Incorrect bidirectional calibration. Perform bidirectional calibration (page E-43). • Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move away from large metal objects and try again. Note that digital compass operation cannot be performed inside a train, boat, etc.
Question: Why am I having problems taking direction readings indoors ? Answer: A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism readings. Move away from the object causing the interference or take the direction reading outdoors. Indoor direction readings are particularly difficult inside ferro-concrete structures. Remember that you will not be able to take direction readings inside of trains, airplanes, etc.
Question: How does the altimeter work? Answer: Generally, air pressure and temperature decrease as altitude increases. This watch bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO). These values define relationships between altitude, air pressure, and temperature.
• Note that the following conditions will prevent you from obtaining accurate readings: When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact E-105
There are two standard methods of expressing altitude: Absolute altitude and relative altitude. Absolute altitude expresses an absolute height above sea level. Relative altitude expresses the difference between the height of two different places.
Precautions Concerning Simultaneous Measurement of Altitude and Temperature Though you can perform altitude and temperature measurements at the same time, you should remember that each of these measurements requires different conditions for best results. With temperature measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat.
Power Supply This watch is equipped with a solar cell and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging. Example: Orient the watch so its face is pointing at a light source. • The illustration shows how to position a watch with a resin band. • Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.
Important! • Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause rechargeable battery power to run down. Be sure that the watch is exposed to bright light whenever possible. • This watch uses a special rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required.
Battery Power Indicator and Recover Indicator The battery power indicator on the display shows you the current status of the rechargeable battery’s power. Level Battery Power Indicator 1 2 l l l l l lll l ll ll 3 l l l l l ll l l lllllll All functions enabled. All functions enabled. Auto and manual receive, illumination, beeper, and sensor operation disabled.
• The flashing LOW indicator at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible. • At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (indicated by M indicator) after falling to Level 5, reconfigure the current time, date, and other settings. • Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.
Recover indicator • Performing multiple sensor, illumination, or beeper operations during a short period may cause R (recover) to appear on the display. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers. After some time, battery power will recover and R (recover) will disappear, indicating that the above functions are enabled again.
Charging Precautions Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature. Warning! Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot.
Charging Guide After a full charge, timekeeping remains enabled for up to about five months. • The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations.
▲ ▲ ▲ Recovery Times The table below shows the amount exposure that is required to take the battery from one level to the next.

Reference This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch. Auto Return Features • The watch returns to the Timekeeping Mode automatically if you do not perform any button operation for two or three minutes in the Data Recall, Alarm, Receive, Digital Compass, or Barometer/Thermometer Mode.
Scrolling The A and C buttons are used on the setting screen to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed. Sensor Malfunction Indicator Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal circuitry. When this happens, ERR (error) will appear on the display and sensor operations will be disabled.
• If ERR appears while a measurement operation is being performed in a sensor mode, restart the measurement. If ERR appears on the display again, it can mean there is something wrong with the sensor. • Even if battery power is at Level 1 or Level 2, the Digital Compass Mode, Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. In this case, ERR will appear on the display.
Button Operation Tone Mute indicator The button operation tone sounds any time you press one of the watch’s buttons. You can turn the button operation tone on or off as desired. • Even if you turn off the button operation tone, the alarm, Hourly Time Signal, and Countdown Timer Mode alarm all operate normally. To turn the button operation tone on and off In any mode (except when a setting screen is on the display), hold down D to toggle the button operation tone on ( not displayed) and off ( displayed).
Power Saving When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving. • There actually are two sleep state levels: “display sleep” and “function sleep”.
• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state. • The watch will not enter the sleep state while the digital time is between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when the digital time reaches 6:00 AM, however, it will remain in the sleep state. • The watch will not enter the sleep state while it is in the Digital Compass, Barometer/Thermometer, Altimeter, Receive, Countdown Timer, or Stopwatch Mode.

Press A to toggle Power Saving on (ON) and off (OFF). 4. Press E to exit the setting screen. • The Power Saving on indicator (PS) is on the display in all modes while Power Saving is turned on.
Radio-controlled Atomic Timekeeping Precautions • Strong electrostatic charge can result in the wrong time being set. • The time calibration signal bounces off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.
• Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signal conditions can limit reception to time data only. • If you are in an area where proper time calibration signal reception is impossible, the watch keeps the time with the precision noted in “Specifications”.
Transmitters The time calibration signal received by this watch depends on the currently selected Home City code (page E-13). • When a U.S. time zone is selected, the watch receives the time calibration signal transmitted from the United States (Fort Collins). • When a Japanese time zone is selected, the watch receives the time calibration signal transmitted from Japan (Fukushima and Fukuoka/Saga).
When PAR, BER, or ATH is selected as the Home City code: In this case: The first signal search operation after the Home City code has been changed The second and subsequent signal searches The watch does this: 1. Checks the Mainflingen signal first. 2. If the Mainflingen signal cannot be received, checks the Anthorn signal. 1. Checks the signal of the transmitter of the first receive operation (Anthorn or Mainflingen). 2. If the checked signal cannot be received, checks the other signal.
Timekeeping • Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes. • With the 12-hour format, the P (PM) indicator appears on the display for times in the range of noon to 11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m. • With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.
Illumination Precautions • The electro-luminescent panel that provides illumination loses power after very long use. • Illumination may be hard to see when viewed under direct sunlight. • Illumination turns off automatically whenever an alarm sounds. • The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction. • Frequent use of illumination runs down the battery.
More than 15 degrees too high • Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground. • Illumination turns off in about one second, even if you keep the watch pointed towards your face. • Static electricity or magnetic force can interfere with proper operation of the auto light switch.
Barometer and Thermometer Precautions • The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications. • Sudden temperature changes can affect pressure sensor readings. • Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture.
Important! • Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer. • Incorrectly calibrating the temperature sensor can result in incorrect readings.

Operating Precautions Water Resistance • The following applies to watches with WATER RESIST or WATER RESISTANT marked on the back cover.
• Watches that do not have WATER RESIST or WATER RESISTANT marked on the back cover are not protected against the effects of sweat. Avoid using such a watch under conditions where it will be exposed to large amounts of sweat or moisture, or to direct splashing with water. • Even if a watch is water-resistant, do not operate its buttons or crown while it is submersed in water or wet. • Even if a watch is water-resistant, avoid wearing it in the bath or in areas where detergents (soap, shampoo, etc.
• Some water-resistant watches come with fashionable leather bands. Avoid swimming, washing, or any other activity that causes direct exposure of a leather band to water. • The inside surface of the watch glass may fog when the watch is exposed to a sudden drop in temperature. No problem is indicated if the fogging clears up relatively quickly. If the fogging does not clear or if water has gotten into the watch, take the watch in for repair immediately.
• Deterioration, rust, or corrosion of the band can cause it to break, which may result in the watch falling off your wrist and becoming lost. Be sure to take good care of the band and keep it clean. Should you notice any breakage, discoloration, looseness or other problem with the band, immediately contact your original retailer or an authorized CASIO Service Center to have it checked, repaired, or replaced. Note that you will be charged for any repair or replacement of the band.
Impact • Your watch is designed to withstand impact incurred during normal daily use and light activity such as playing catch, tennis, etc. Dropping the watch or otherwise subjecting it to strong impact, however, can lead to malfunction. Note that watches with shock-resistant designs (G-SHOCK, Baby-G, G-ms) can be worn while operating a chain saw or engaging in other activities that generate strong vibration, or while engage in strenuous sports activities (motocross, etc.).
Electrostatic Charge • Exposure to very strong electrostatic charge can cause the watch to display the wrong time. Very strong electrostatic charge even can damage electronic components. • Electrostatic charge can cause the display to go blank momentarily or cause a rainbow effect on the display. Chemicals • Do not allow the watch to come into contact with thinner, gasoline, solvents, oils, or fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain such ingredients.
Resin Components • Allowing the watch to remain in contact with other items or storing it together with other items for long periods while it is wet can cause the color of the other items to transfer to the resin components of the watch. Be sure to dry off the watch thoroughly before storing it and make sure it is not in contact with other items.
Natural Leather and Imitation Leather Bands • Allowing the watch to remain in contact with other items or storing it together with other items while it is wet for long periods can cause the color of the other items to transfer to the natural leather or imitation leather band of the watch. Be sure to dry off the watch thoroughly before storing it and make sure it is not in contact with other items.
Metal Components • Failure to clean dirt from a metal band can lead to formation of rust, even if the band is stainless steel or plated. If the watch is exposed to sweat or water, wipe it thoroughly with a soft, absorbent cloth and then store it in a well-ventilated location to dry. • To clean the band, use a soft toothbrush or similar tool to scrub it with a weak solution of water and a mild neutral detergent. Take care to avoid getting solution on the watch case.
Display • Display figures may be difficult to read when viewed from an angle. Data Protection • Allowing the battery to go dead, replacing the battery, or having the watch repaired can cause all data in the watch’s memory to be lost. Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damages or losses caused by data lost due to malfunction or repair of the watch, replacement of the battery, etc. Be sure to keep separate written copies of all important data.
User Maintenance Caring for Your Watch • A dirty or rusty case or band can soil the sleeve of your clothing, cause skin irritation, and even interfere with watch performance. Be sure to keep the case and band clean at all times. Rust tends to form easily after the watch is exposed to seawater and then left without cleaning. • Sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any affect on your skin or clothing. Wipe the band with a cloth to clean it.
• Remember that you wear your watch next to your skin, just like a piece of clothing. Because of this, you should always keep your watch clean. Use a soft, absorbent cloth to wipe off any dirt, sweat, water, or other foreign matter from the case and band. Dangers of Poor Watch Care Rust • Though the stainless steel used for the watch is highly rust-resistant, rust can form if the watch is not cleaned after it becomes dirty.
Skin Irritation • Individuals with sensitive skin or in poor physical condition may experience skin irritation when wearing a watch. Such individuals should keep their leather band or resin band particularly clean, or switch to a metal band. Should you ever experience a rash or other skin irritation, immediately remove the watch and contact a skin care professional.
