Setting range: From 12:00 AM on January 1, 2000 to 11:59 PM on December 31, 2099 City names that can be set: Those cities that have been set to "ON" with the zone setting function Display range: When displaying remaining time: • Remaining time is displayed from 99 hours, 59 minutes and 59 seconds to 0 hours, 00 minutes and 00 seconds. "ER" is displayed when the remaining time exceeds 100 hours.
12. Using Zone Setting [Destination Timer] B A Display of remaining time Display of arrival time The zone setting function enables only those cities for which "SET" has been selected to be easily accessed (displayed) in each mode. Daylight savings time can be also be set for each city. In addition, the user is also able to arbitrarily register one city and time difference.
1. Turn the crown while in the normal position and set the mode hand to the mode setting [SET] mode. 2. The city can be changed by pulling out the crown to the first click (for changing cities between SET and OFF and for setting the location for switching to daylight savings time). 3. Turn the crown to access the city to be set. • Turning the crown continuously causes the cities to advance rapidly. 4.
3. Turning the crown displays those characters that are used for city names. • Turning the crown continuously causes the characters to advance rapidly. 4. The correction location changes each time button (A) is pressed. 5. When button (A) is pressed during the correction state of the first character of the city name, the watch enters the correction state for the time difference from UTC. 6. Turn the crown to display the time difference. 7. After setting, return the crown to the normal position.
13. Low Battery Warning Function The location having the same time difference among the 30 cities pre-registered in this watch is displayed first. However, a city is not displayed if the time difference of a registered city has not been set. When battery capacity becomes low, the second hand begins to move two graduations (two seconds) at a time to inform the wearer that the battery has nearly reached the end of its life.
Notes: • The crown can only be operated to change the mode (crown 0 click position). • The buttons can only be used to change the city name (UP/DOWN). • The EL light is not illuminated even if the button is pressed. • The alarm tone does not sound even if the alarm is set. • The chronograph stops measuring time even if measurement is in progress and is reset. • Although the destination timer tone does not sound even if measurement is completed, measurement continues. 15.
1. Turn the crown to set the mode hand to the chronograph [CHR] mode. 2. Pull out the crown to the second click. • The second hand, minute hand, hour hand, 24 hour hand, UTC hour hand and UTC minute hand rapidly advance to the 0 position stored in memory. 3.

16. Using the Register Ring The bezel design may vary depending on the model. [Calculation function] 60 NA UT. Speed index 70 70 ST AT . 8 8 0 0 80 10 10 A. Navlgational calculation 55 90 Note the following points when using this function. Use the calculation function of this watch only as a guide.These scales do not indicate the position of the decimal point.
Answer. Align “25” on the outer scale with “10” on the inner scale. Then, “23” on the inner scale corresponds to “57.5” on the outer scale. Thus, the difference in altitude is 5,750 feet. 8) Rate of climb (or descent) The rate of climb (or descent) can be obtained from the time required to reach an altitude. Example: Obtain the rate of climb when an aircraft reaches an altitude of 7,500 feet after climbing for 16 minutes. Answer. Align “75” on the outer scale with “16” on the inner scale.
For correct use within the design limits of the watch, confirm the level of waterresistance of your watch, as indicated on the dial and case, and consult the table. 17. Precautions CAUTION: Water-resistance performance Examples of use There are several types of water-resistant watches, as shown in the following table. The unit "bar" is roughly equal to 1 atmosphere. * WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar. Indication Specification Minor exposure to water (washing face, rain, etc.
• Water-resistance for daily use (to 3 atmospheres): This type of watch is waterresistant to minor exposure to water. For example, you may wear the watch while washing your face; however, it is not designed for use underwater. • Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is water-resistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed for use while skin diving.
NOTE: Avoid using solvents (thinner, benzine, etc.), as they may mar the finish. WARNING: Handling of the battery • Keep the battery out of the reach of small children. If a child swallows the battery, contact a physician immediately. CAUTION: Replacing the battery • For replacement of the battery, take your watch to your dealer or Citizen Service Center. • Replace the battery as soon as possible if the service life of the battery has expired.
