When the SMH10 is not working properly or is in faulty status for any reason, you may reset by pushing the pin-hole reset button at the back of the headset main unit. Insert a paper clip into the reset pinhole
and press the reset button for a second with light pressure. The SMH10 will be switched off, and you have to turn the system back on and try again. However, this will not restore the headset to factory default settings.
