Maintenance and Service

●Refer to the information in this chapter before contacting a service technician.
●When shipping the unit
Please save the original shipping carton and packing materials. If you need to ship the unit, for maximum protection, re-pack the
unit as it was originally packed at the factory.
●Keeping the exterior surfaces clean
Do not use volatile liquids such as insecticide spray near the unit. Do not leave rubber or plastic products in contact with the unit for
a long period of time since they leave marks on the surface.
●Cleaning the unit
To clean the player, use a soft, dry cloth. If the surfaces are extremely dirty, use a soft cloth lightly moistened with a mild detergent
solution. Do not use strong solvents such as alcohol, benzine or thinner, as these might damage the surface of the unit.
●Maintaining the unit
The DVD player is a high-tech, precision device. If the optical pick-up lens and disc drive parts are dirty or worn, the picture quality
could be diminished. Depending on the operating environment, regular inspection and maintenance are recommended after every
1,000 hours of use. For details, please contact your nearest authorized service center.
