Resetting the Unit
If the unit experiences a power surge or electric shock, it is possible that the internal micro-controller
may lock up and the unit will not respond to any commands from the panel controls.
In this event, use a straightened paper clip, toothpick or similar objects to press the RESET button located at rear of the
unit (see the below figure) then press and hold the LOCK button for around 3 seconds.
The reset operation clears the system memory and all of your previous settings will be erased.
