4.5 Checking the Battery Level
You can check the battery level in two different ways when the
headset is powering on.
4.5.1 LED Indicator
When the headset is powering on, the red LED flashes rapidly
indicating the battery level.
4 flashes = High, 70~100%
3 flashes = Medium, 30~70%
2 flashes = Low, 0~30%
4.5.2 Voice Prompt Indicator
When you power on the headset, keep pressing the Center Button
and the (+) Button simultaneously for several seconds until you
hear high tone triple beeps. Then you will hear 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 of
battery level indication.
You can easily adjust the volume by tapping the (+) Button or the (-)
Button. You will hear a beep when the volume reaches maximum or
minimum level. The volume is set and maintained independently at
different levels for each audio source even when you turn off and
on the headset. For example, once you set the volume for mobile
phone handsfree, it will not change even if you adjust the volume
when you hear Bluetooth MP3 music. So you can always maintain
the preferred optimum volume level for each audio source.
