4.2 Low Battery Warning
When the battery is low, the blinking blue LED in stand-by mode turns
to red and you will hear three, mid-toned beeps and a voice prompt
saying “Low Battery”.
4.3 Checking the Battery Level
You can check the battery level in two different ways when the headset
is powering on.
4.3.1 LED Indicator
When the headset is powering on, the red LED ashes rapidly
indicating the battery level.
4 ashes = High, 70~100%
3 ashes = Medium, 30~70%
2 ashes = Low, 0~30%
Note:
1. The battery performance may be reduced over time with usage.
2. Battery life may vary depending on conditions, environmental factors,
functions of the product in use, and devices used with it.
4.3.2 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 three,
high toned 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 for the battery level indication.
4.4 Powering On and Off
Press the Jog Dial and the Phone Button at the same time to power the
headset either on or off. When powering on the headset, press the Jog
Dial and the Phone button at the same time until the blue LED appears
while hearing the ascending beeps. When powering off the headset,
press the Jog Dial and the Phone Button at the same time until the
red LED appears briey and the headset turns off completely while
hearing descending beeps.
