4.4 Checking the Battery Level

4.4.1 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%
4.4.2 Voice Prompt Indicator
When you power on the headset, keep pressing the (+) Button
and the (-) Button simultaneously for about 3 seconds until you
hear three, high toned 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 a voice prompt
for the battery level indication.

4.5 Volume Adjustment

You can easily adjust the volume by tapping the (+) Button or the (-)
Button. You will hear a beep when the volume reaches the maximum
or minimum level. The volume is set and maintained independently at
different levels for each audio source even when you reboot the
headset. For example, once you set the volume for mobile phone
handsfree, it will not change even if you adjust the volume for your
Bluetooth MP3 music. However, if you adjust the volume during
stand-by mode, it will affect volume levels of every audio source.
