Checking the Battery Level
When the headset or the Handlebar Remote is powering on, their red LED flashes rapidly indicating the battery level.
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 the (+) Button and the (−) Button simultaneously for about 3 seconds until you hear three, high toned 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 indication.
1. The battery performance may be reduced over time with usage.
