•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 (CHG), all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (M) after falling to Level 5 (CHG), reconfigure the current time, date, and other settings.
•Display indicators reappear as soon as the battery is charged from Level 5 (CHG) to Level 2 (M).
•The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5 (CHG). With this Home City code setting, the watch is configured to receive the time calibration signals of Japan. If you are using the watch in North America or Europe, or China you will need to change the Home City code setting to match your location whenever the battery drops to Level 5 (CHG).
•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.
