Operation Guide 2628
•The flashing CHARGE 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 4, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 3 (indicated by the flashing CHARGE indicator) from Level 4. You will not be able to configure any of the other settings until the battery reaches Level 2 (no charge indicator) after dropping to Level 4.
•Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to show a reading that momentarily is higher than the actual battery level. The correct battery power indicator should appear after a few minutes.
•If you use the light or alarms a number of times during a short period, the recover indicator appears and the following operations become disabled until battery power recovers.
Illumination Beeper tone
Calibration signal reception
After some time, battery power will recover and the recover indicator 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. 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
Charging Guide
After a full charge, timekeeping remains enabled for up to about seven 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.

|
|
Sunlight Through a Window (10,000 lux) | 24 minutes |
|
|

•Display on 18 hours per day, sleep state 6 hours per day
•1 illumination operation (1.5 seconds) per day
•10 seconds of alarm operation per day
•5 times calibration reception per day
•Stable operation is promoted by frequent charging.

Note
•Auto DST (AUTO) can be selected only while HNL, ANC, LAX, DEN, CHI, or NYC is selected as the Home City code. For more information, see “Daylight Saving Time (DST)” below.
•The auto receive setting is used for time calibration signal reception only. See “About Auto Receive” for details.
•For details about power saving, see “Power Saving Function”.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.
The time calibration signal transmitted from Fort Collins includes both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the received time signal.
•The default DST setting is Auto DST (AUTO) whenever you select ANC, LAX, DEN, CHI, or NYC as your Home City code.
•If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually.
To change the Daylight Saving Time (summer time) setting
1.In the Timekeeping Mode, hold down Auntil the city code starts to flash, which indicates the setting screen.
2.Press Cand the DST setting screen appears.
3.Use Dto cycle through the DST settings in the sequence shown below.
