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 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 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 an AM
radio or digital camera (including a cellular phone with built-in
camera) to see if it is sending out an infrared signal.
• With an AM radio:
Tune the AM radio station to a non-
broadcasting frequency. Point the remote
control towards it, push any button and
listen. If the sound from the radio fl utters, it is
receiving the remote control’s infrared signal.
• With a digital camera
(including built-in cell phone cameras):
Point a digital camera towards the remote
control. Push any button on the remote control
and look through the digital camera. If the
infrared light appears through the camera, the
remote control is working.
