Battery Recovery
Recover indicator
•Performing multiple sensor, illumination, or beeper operations during a short period may cause LMH to appear on the display, indicating that the watch has disabled some functions to allow battery power to recover. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.
After some time, battery power will recover and LMH will disappear, indicating that the above functions are enabled again.
•Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer Mode or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. This is indicated by LMH on the display.
•If LMH appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.
