Product Service

Do not attempt to remove the cover(s) or repair the unit yourself.

Refer servicing to qualified personnel only.

The servicer will require all components to service your system.

Therefore, should service ever be necessary, be sure to bring the

entire system.

Product information

For product service, product information or assistance with product

operation, refer to the servicenter directory.

Before moving your system to another location, be sure to

remove all discs from the rack and turn off the system.

The changer mechanism automatically locks when the system

is turned off, to protect it against damage in transport.

Therefore, always press POWER and make sure "GOOD

BYE" appears on the display before you unplug the system.

Failure to do so will expose the CDs and the system to the risk

of severe damage.
