24. MAINTENANCE

■ Servicing
• Please refer to relevant topics on "TROUBLESHOOTING" on page 70 before returning the product.
• If this unit becomes inoperative, do not try to correct the problem by yourself. There are no user-serviceable
parts inside. Eject the disc (if possible), remove the SD Memory Card, place the unit into the standby mode,
unplug the power plug, and please contact:
1-800-605-8610 or visit : www.magnavox.com/support
■ Cleaning the Cabinet
• Wipe the front panel and other exterior surfaces of the unit with a soft cloth.
• Never use a solvent, thinner, benzene or alcohol to clean the unit. Do not spray insecticide liquid near the unit.
Such chemicals may discolor the surface or damage the unit.
■ Cleaning Discs
• When a disc becomes dirty, clean it with a cleaning cloth. Wipe the disc from the center to outside. Do not wipe
in a circular motion.
• Do not use solvents such as benzine, thinner, commercially available cleaners, detergent, abrasive cleaning agents
or antistatic spray intended for analog records.
■ Cleaning the Disc Lens
• If this unit still does not perform properly although you refer to the relevant sections and to
"TROUBLESHOOTING" in this owner's manual, the laser optical pickup unit may be dirty. Consult your dealer or
an Authorized Service Center for inspection and cleaning of the laser optical pickup unit.
■ Disc Handling
• Handle the discs so that fingerprints and dust do not adhere to the surfaces of the discs.
• Always store the disc in its protective case when it is not used.
• Note that discs with special shapes (heart-shaped discs, octagonal discs, etc.) cannot be played back on this unit.
Do not attempt to play such discs, as they may damage the unit.
■ 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. See next.
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.
