• The LOW indicator at Level 3 (L) and the flashing charge indicator (CHG) at Level 4
tell 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. 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 4
(CHG) (indicated by the flashing charge indicator) from Level 5. You will not be able
to configure any of the other settings until the battery reaches Level 3 (L) (no charge
indicator) after dropping to Level 5.
• Leaving the watch in direct sunlight or some other very strong light source can
cause the battery power indicator to show a reading that is momentarily higher than
the actual battery level. The correct battery power indicator should appear after a
few minutes.
• Frequent use of illumination or the alarm over a short period will cause the recover
indicator ( ) to appear in the lower display, indicating that the following operations
are disabled until battery power recovers.
Illumination
Beeper tone
Time calibration signal reception
