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.
1. In this event, unplug and then reconnect the AC-DC power adaptor into the wall outlet.
2. Use a straightened paper clip, toothpick or similar objects to press the RESET button located at
the rear of the main unit (see the below figure). The reset operation clears the system memory
and all of your previous settings will be erased.
Caution: Do not use a sharp, pointed object to press the reset button. It may damage the
reset switch inside the unit.
