When the Sena Expand is not working properly or is faulty for any reason, you may reset it by pushing
the pinhole reset button at the back of the headset main unit.
1. Rotate the speaker pad of the left headset counterclockwise to detach it.
2. Insert a paper clip into the reset pin-hole and press the reset button for a second using light pressure. The Sena Expand will be switched off, and you have to turn the system back on and try again. However, this will not restore the headset to the factory default settings.
