Checking Battery Level

You can check the battery level in two different ways when the headset

is powering on.

LED Indicator

When the headset is powering on, the red LED flashes rapidly indicating

the battery level.

LED Status

4 flashes High, 70~100%

3 flashes Medium, 30~70%

2 flashes Low, 0~30%

Voice Prompt Indicator

When you power on the headset, keep pressing and holding the (+)

Button and (-) 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.

Note:

1. The USB power & data cable is also used for ﬁrmware upgrade of the SMH3.

2. The USB wall charger is not included in the package. Any 3rd party USB
