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.
