Resetting the headset
If the headset cannot be turned on or cannot be operated even when it is turned on, reset the headset.
Place the headset into the charging case, leave the lid of the charging case open, then hold your finger to the touch sensor on the left unit for about 20 seconds.
Release your finger when the indicator (red) of the headset turns off after flashing.
Then hold your finger to the touch sensor on the right unit for about 20 seconds.
Release your finger when the indicator (red) of the headset turns off after flashing.
If the indicator (blue) on the headset flashes, the headset may not have been reset properly because the headset moved in the charging case. Perform the resetting operation again.
The device registration (pairing) information and other settings are retained.
If the headset does not operate correctly even after resetting, initialize the headset to restore factory settings.
