Resetting the headset
If the headset cannot be turned on, or if it cannot be operated even when it is turned on, reset the headset. When the charging starts, the indicator (red) of the headset turns off after 10 seconds then the headset is reset automatically. Pairing information and other settings are not deleted by this operation.
If the headset does not operate correctly even after resetting, initialize the headset to restore factory settings.
