Resetting the headset
If the headset cannot be turned on or cannot be operated even when it is turned on, reset the headset.
- Connect the headset to an AC outlet.
Use the supplied USB Type-C cable and a commercially available USB AC adaptor (A).
- Press and hold the
(power) button (B) and the NC/AMB (noise canceling/Ambient Sound Mode) button (C) for about 5 seconds.
The headset will be reset (the charging indicator turns off and then lights up again).
The pairing information and other settings are retained.
If the headset does not operate correctly even after resetting, initialize the headset to restore factory settings.
