Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.
•On the dashboard of a car parked in direct sunlight
•Too close to an incandescent lamp
•Under direct sunlight
|
|
Important!
•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.
•Turn on the watch’s Power Saving function (page
•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 power to run down. Expose the watch to bright light whenever possible.
Power Levels
You can check the current battery power level by viewing the battery power indicator that appears on the digital display when you enter the Timekeeping Mode.
•To enter the Timekeeping Mode from any other mode, hold down D for about two seconds.

•The flashing L 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 (M) 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 (M).
•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.
•All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
Charging Required Indication (by second hand)
When battery power reaches Level 3, the second hand of the watch will jump at
Power Recovery Mode
•Repeated sensor measurement, illumination, or use of tones over a short period of time may cause the watch to enter a power recovery mode, which is indicated by a recovery indicator (R) to flash on the digital display. The watch will remain in the power recovery mode until battery power recovers.
•Illumination, tones, and sensor operations are disabled and the hands of the watch stop until battery power recovers.
•Battery power takes about 15 minutes to recover. The recovery indicator (R) will stop flashing and normal watch operation will be restored when battery recovery is complete.
•Frequent flashing of the recovery indicator (R) indicates that battery power is low. Expose the watch to light to charge its battery.

Power Saving
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”.
•With this watch, the Power Saving function cannot be disabled.

•The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.
•You will not be able to enter the Compass, Barometer/Thermometer, Altimeter, Stopwatch, or Countdown Timer Mode while the watch is in a sleep state.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Configuring Current Time and Date Settings Manually” (page
This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

Important!
•The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
•When HONG KONG (HKG) is selected as the Home City, only the time and date are adjusted according to the time calibration signal. You need to switch manually between standard time and daylight saving time (DST) if required. See “To configure Home City settings” (page
