When the Tufftalk Lite is not working properly or is in faulty status for any reason, you may reset by pushing the pin-hole reset button located below the Center Button. Separate the left ear cup and insert a paper clip into the reset pin-hole and press the reset button for a second with light pressure. The Tufftalk Lite will be switched off. Restart the system and try again. This will not restore the headset to factory default settings.
