4.4 Low Battery Warning

When the battery is low, the blinking blue LED in stand-

by mode turns to red and you will hear mid-tone triple

beeps and a voice prompt saying “Low Battery”.

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

Jog Dial and Phone Button simultaneously for about

3 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.

5. VOLUME ADJUSTMENT

You can easily adjust the volume by rotating the Jog

Dial. 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.
