Checking Battery Level
You can check the battery level in two different ways when the headset
is powering on.
LED Indicator
When the headset is powering on, the red LED flashes rapidly indicating
the battery level.
LED Status
4 flashes High, 70~100%
3 flashes Medium, 30~70%
2 flashes Low, 0~30%
Voice Prompt Indicator
When you power on the headset, keep pressing and holding the (+)
Button and (-) Button simultaneously for about 3 seconds until you hear
three high tone beeps. Then you will hear a voice prompt indicating the
battery level. However, if you release the buttons as soon as the headset
turns on, you will not hear the voice prompt for the battery level.
Note:
