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.
