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 Jog Dial and the Phone Button simultaneously for about 3 seconds
until you hear high tone triple beeps. Then you will hear a voice prompt indicating the battery level is high, medium, or low.
4.5 Volume Adjustment
You can easily adjust the volume by rotating the Jog Dial. 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. Therefore, you can always maintain the preferred optimum volume level
for each audio source.
