5. CHECKING THE BATTERY LEVEL
You can check the battery level in two different ways when the
headset is powering on.
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%
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
three high tone 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 the voice prompt for the battery
level.
