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 calibrate the bearing sensor (page E-41) if you suspect the direction reading is incorrect. • See “Using the Digital Compass While Mountain Climbing or Hiking” (page E-48) for some real-life examples of how to use this feature.
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, all of 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. Use the direction indicators imprinted on the bezel to record the indicated direction. For details, see “Using the Digital Compass While Mountain Climbing or Hiking” (page E-48).
• Any ongoing direction measurement operation is paused temporarily while the watch is performing an alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressing L). The measurement operation resumes for its remaining duration after the operation that caused it to pause is finished. • 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 also are 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 and magnetic declination angle direction values start to flash on the display. This is the setting screen. 2. Use A (+) and C (–) to change the magnetic declination angle and magnetic declination angle direction settings. • You can select a value within the range of W 90° to E 90° with these settings.
• You can turn off (OFF) magnetic declination correction (which effectively makes the magnetic declination angle: 0°) by pressing A and C at the same time. • The illustration on page E-43, 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. 3. When the setting is the way you want, press E to exit the setting screen.
l l ll lll lll To perform bidirectional calibration 1. In the Digital Compass Mode, hold down E for about two seconds until the magnetic declination angle and magnetic declination angle direction values start to flash on the display. This is the setting screen. 2. Press D 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. llll 3.
5. Press C again to calibrate the second direction. • 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.
Using the Digital Compass While Mountain Climbing or Hiking This section describes three real-life situations where you could use the watch’s built-in digital compass. • To set a map and find your current location (page E-49) 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 Objective Current location N E-50 12 o’clock position 1. Take a compass reading and then 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. 2. Set the map so the direction you want to travel on the map is pointed straight in front of you. 3.
• This will position the map relative to 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 Note • The following procedure is possible only with a watch that has a rotary bezel. 1. Take a compass reading and then 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.
4. Rotate the bezel so the “N” (North) indicator on the bezel is aligned with the north indicator produced by the reading in step 3. 5. To advance to your objective proceed in the direction that 12 o’clock is pointing. Note • When mountain climbing or hiking, conditions or geographic contours may make it impossible for you to advance in a straight line. If this happens, return to step 1 and save a new direction to the objective.
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-141) 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.x°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 barometric pressure 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. 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. Important! • This watch estimates altitude based on air pressure.
• 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. • Do not use this watch for measuring altitude in applications that demand professional or industrial level precision. • Remember that the air inside of a commercial aircraft is pressurized.
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 produced by the watch will be more accurate 400 than they would without a reference altitude.
To display your current altitude 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. Leave the watch in the Altimeter Mode if you want the displayed altitude value and the altitude graph contents to be updated at Current time regular intervals.
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-68). • 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 The watch automatically keeps track of the high altitude achieved to date. You also can save altitude readings with the touch of a button. • You can recall and view altitude data using the Data Recall Mode. For details, see “Recalling Altitude Data” (page E-70).
llllll ll ll To save an altitude reading 1. Press A to enter the Altimeter Mode (page E-11). 2. Hold down A until REC flashes on the display. • At this time the watch will beep and the current altitude reading value will be saved along with the reading date (month - day) and time. 3. REC will stop flashing and the watch will return to the Altimeter Mode automatically after data save is complete. ll l l l ll • Memory can store up to 24 altitude records.
Specifying a Reference Altitude After you specify a reference altitude, the watch adjusts its air-pressure-toaltitude conversion calculation accordingly. The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude whenever one is available during your climb. l llll l llll E-68 lll lll llll llll To set a reference altitude 1.
• Pressing A and C at the same time returns to OFF (no reference altitude), so the watch performs air pressure to altitude conversions based on preset data only. 3. Press E to exit the setting screen. 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.
Recalling Altitude Data In the Data Recall Mode, you can recall and view altitude reading records you stored in the Altimeter Mode, as well as the high altitude record. • All of the operations in this section are performed in the Data Recall Mode (page E-10). Data Screens The following explains the contents of each of the screens that appear in the Data Recall Mode.
Note • While the altitude record or high altitude screen is displayed, the bottom part of the display alternates between the measurement date (month and day) and measurement time, at 1-second intervals. Altitude ▲ Alternates at 1-second intervals. Measurement date (Month – Day) ▲ Altitude record indicator Measurement time (Hour : Minute) To view altitude reading records and the high altitude record 1.

llllll ll ll To delete all altitude data currently in memory ll l l l ll E-72 1. In the Data Recall Mode, hold down E until CLR flashes on the display and the watch beeps twice. • Releasing E at any time while CLR is flashing on the display will cancel the delete operation. 2. Keep E depressed for two seconds. • The watch will beep to indicate that all of the altitude data stored in watch memory (including readings you stored and the high altitude value) is deleted.
Tide/Moon Data In the Tide/Moon Data Mode, you can see the current tide and the current date’s Moon phase for your Home City. You can specify a date and view tide and Moon data for that date. • See “Moon Phase Indicator” (page E-122) for information about the Moon phase indicator and “Tide Graph” (page E-125) for information about the tide graph. • All of the operations in this section are performed in the Tide/Moon Data Mode (page E-10).
Tide Data The Tide Graph that appears first when you enter the Tide/Moon Data Mode shows the data at 6:00 a.m. for your currently selected Home City on the current date, according to the Timekeeping Mode. From there you can specify another date or time. • If the tide data is not correct, check your Timekeeping Mode settings and correct them if necessary. • If you feel that the information shown by the Tide Graph is different from actual tide conditions, you need to adjust the high tide time.
• If the Moon phase indicator shows a phase that is a mirror image of the actual moon phase in your area, you can use the procedure under “Reversing the Displayed Moon Phase” (page E-79) to change it.

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-137) for other important information about using illumination.
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. It does not illuminate the display under bright light. • The auto light switch is always disabled, regardless of its on/off setting, when any one of the following conditions exists.
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. More than 40° lll lll lll Parallel to ground ll 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-44). • 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 altitude readings: When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact E-102
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 Indicators 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 Battery power indicator lllll lllll lllll Function Status All functions enabled. All functions enabled.

• 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.
ll ll lllll • Performing multiple sensor, illumination, or beeper operations during a short period may cause all of the battery indicators (L, M, H) to flash 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 battery indicators (L, M, H) 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. Moon Phases and Moon Age The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon appears to wax and wane as the relative positioning of the Earth, Moon, and Sun changes. The greater the angular distance between the Moon and the Sun,* the more we see illuminated.
Moon Phase Indicator Moon Phase indicator E-122 The Moon phase indicator of this watch indicates the current phase of the Moon as shown below. It is based on the view of the left side of the moon at meridian transit from the northern hemisphere of the Earth. If the appearance of the Moon phase indicator is reversed from the actual Moon as viewed from your location, you can use the procedure under “To reverse the displayed Moon phase” (page E-80) to change the indicator.

Tidal Movements Tides are the periodic rise and fall of the water of oceans, seas, bays, and other bodies of water caused mainly by the gravitational interactions between the Earth, Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal interval.
Tide Graph The Tide Graph graphically represents the current tide condition using one of three patterns that represent spring tide, intermediate tide, and neap tide, as shown below. Tide Name Spring Tide Intermediate Tide Neap Tide Graph Description Large difference between high tide and low tide. Occurs a few days before and after a New Moon and Full Moon. Medium difference between high tide and low tide. Small difference between high tide and low tide.
• The Tide Graph flashes as shown below to indicate the tide range. ll lll ll ll l l l l ll High tide Low tide High tide • The segments on either end of the Tide Graph flash during high tide. Lunitidal Interval Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about six hours later. Actual high tide occurs somewhat later, due to factors such as viscosity, friction, and underwater topography.
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 Tide/Moon Data, Alarm, Data Recall, Receive, Digital Compass, or Barometer/ Thermometer Mode. • If you do not perform any button operation while in the Altimeter Mode, the watch returns to the Timekeeping Mode automatically after nine or 10 hours.
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.
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.
To turn Power Saving on and off lllll lllll llllll llllll Power Saving on indicator E-132 1. In the Timekeeping Mode, hold down E until the city code starts to flash, which indicates the setting screen. 2. Press D nine times until the Power Saving on/off screen appears. 3. 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, minute, second) 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-14). • 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).
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.
• The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation. Illumination Precautions • The electro-luminescent panel that provides illumination loses power after very long use.
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display. • Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery.
• Under certain conditions, illumination does not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction. • You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
Pressure Sensor and Temperature Sensor Calibration The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no further adjustment. If you notice serious errors in the pressure readings and temperature readings produced by the watch, you can calibrate the sensor to correct the errors. Important! • Incorrectly calibrating the barometric pressure 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.
• In order to maintain water resistance, have the gaskets of your watch replace periodically (about once every two or three years). • A trained technician will know how to check your watch for proper water resistance whenever you have its battery replaced. Battery replacement requires the use of special tools. Always request battery replacement from your original retailer or from an authorized CASIO Service Center. • Some water-resistant watches come with fashionable leather bands.
Temperature • Never leave the watch on the dashboard of a car, near a heater, or in any other location that is subject to very high temperatures. Do not leave the watch where it will be exposed to very low temperatures, either. Temperature extremes can cause the watch to lose or gain time, to stop, or otherwise malfunction. • Leaving the watch in an area hotter than +60°C for long periods can lead to problems with its LCD.
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.
• Failure to clean dirt from the watch for long periods can cause fluorescent color to fade. Wash dirt off with water as soon as possible and then dry the watch. • Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high temperatures for long periods. • Contact an authorized CASIO Service Center to have resin components replaced. Note that you will be charged for replacement costs.
Bacteria and Odor Resistant Band • The bacteria and odor resistant band protects against odor generated by the formation of bacteria from sweat, which ensures good comfort and hygiene. In order to ensure maximum bacteria and odor resistance, keep the band clean. Use an absorbent soft cloth to wipe the band clean of dirt, sweat, and moisture. The bacteria and odor resistant band suppresses the formation of organisms and bacteria. It does not protect against rash due to allergic reaction, etc.
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.
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. Battery • The special rechargeable (secondary) battery used by your watch is not intended to be removed or replaced by you.
