| |
|
| where it is exposed to light. For details, see “Charging the |

2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To configure Home City settings” to configure your Home City and daylight saving time settings.
Important!
Proper time calibration signal reception, and World Time Mode and Sunrise/Sunset Mode data depend on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you configure these settings correctly.
3.Set the current time.
•To set the time using a time calibration signal See “To get ready for a receive operation”.
•To set the time manually
See “Configuring Current Time and Date Settings Manually”.
The watch is now ready for use.
•For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic Timekeeping”.
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a

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 and keep it in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.
•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.

•The flashing LOW indicator at Level 3 (L) 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.
Power Recovery Mode
•Performing multiple sensor, illumination, or beeper operations during a short period may cause all of the battery power indicators (H, M, and L) to start flashing on the display. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.
•Battery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will stop flashing. This indicates that the functions listed above are enabled again.
•If all of the battery power indicators (H, M, L) are flashing and the C (charge) indicator also is flashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.
•Even if battery power is at Level 1 (H) or Level 2 (M), 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. This is indicated when all of the battery power indicators (H, M, L) are flashing.
•Frequent flashing of all of the battery power indicators (H, M, L) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

*2 Approximate amount of exposure time (in hours) required to take power from one level to the next.
•The above exposure times all are for reference only. Actual exposure times depend on lighting conditions.
•For details about the operating time and daily operating conditions, see the “Power Supply” section of the Specifications.
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”.
Elapsed Time in Dark | Display | Operation | |
60 to 70 minutes (display sleep) | Blank, with PS flashing | Display is off, but all functions are enabled. | |
|
|
| |
6 or 7 days (function sleep) | Blank, with PS not flashing | All functions are disabled, but timekeeping is | |
maintained. | |||
|
|
•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.
•The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.
