Operation Guide 2804
� At Level 4, the display is disabled but timekeeping and other functions continue to operate internally. Pressing any button causes the Timekeeping Mode screen to appear for two or three minutes. � At Level 5, all functions are disabled. Functions are enabled once again after the rechargeable battery is charged, but anything previously stored in memory is lost. Because of this, you must set the current time and alarms, and re-input Data Bank records after the rechargeable battery is charged. � Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to temporarily show a reading that is actually higher than the battery level. The correct battery power indicator should appear after a few minutes. � Frequent backlight and alarm operations over a short period put a heavy load on the battery, which can cause the battery power indicator to flash, indicating that the backlight and alarm are disabled. Normal operations should return after the battery recovers from the overload condition. The above condition can occur after about consecutive 200 backlight operations or about 360 alarm operations.
