Maintenance

Cabinet Cleaning
• Wipe the front panel and other exterior surfaces of the
unit with a soft cloth immersed in lukewarm water and
wrung dry.
• Never use a solvent or alcohol. Do not spray insecticide
liquid near the unit. Such chemicals may cause damage and
discoloration to the exposed surfaces.
Panel Cleaning
Wipe the panel of the unit with a soft cloth. Before cleaning
the panel, disconnect the AC power cord.
Servicing
Should your unit become inoperative, do not try to correct
the problem yourself. There are no user serviceable parts
inside. Turn off the unit, unplug the AC power cord and call
our toll free customer support line found on the cover of this
manual to locate an authorized service center.
IR Signal Check
If the remote control is not working properly, you can use a
digital camera (including a cellular phone with built-in camera)
to see if it is sending out an infrared signal.
With a digital camera
(including built-in cell phone cameras):
Point the Digital Camera towards the remote
control infrared diode at the front of the
remote control. Press any button on the
remote control and look through the camera
display. If the infrared pulsating light appears
through the camera, the remote control is
sending out an IR signal.
