If the SR10 is not working properly or is in a faulty status for any reason, you may reset by pushing the small reset button at the top of the SR10 main unit. By using a paper clip or a pencil tip, lightly press and hold the reset button for 1 second. The SR10 will be switched off. Turn the SR10 back on to use it. However, this will not restore the SR10 to factory default settings.
