Caution:
This operation will erase all data stored in memory including
clock, timer settings, tuner preset, and CD program.
■ Condensation
Sudden temperature changes, storage or operation in an
extremely humid environment may cause condensation
inside the cabinet (CD pickup, etc.) or on the transmitter
on the remote control. Condensation can cause the unit to
malfunction. If this happens, leave the power on with no
disc in the unit until normal playback is possible (about 1
hour). Wipe off any condensation on the transmitter with a
soft cloth before operating the unit.
■ Before transporting the unit
Disconnect all devices and remove all disc from the unit.
Then, set the unit to the power standby mode. Carrying the
unit with other devices left connected or discs left inside
might damage the unit.

Maintenance

■ Cleaning the cabinet
Periodically wipe the cabinet with a soft cloth and a diluted
soap solution, then with a dry cloth.
Caution:
● Do not use chemicals for cleaning (gasoline, paint thinner,
etc.). It may damage the cabinet.
● Do not apply oil to the inside of the unit. It may cause
malfunctions.
■ Cleaning the CD pickup lens
In order to ensure proper operation of the CD player,
preventative maintenance (cleaning of the laser pickup
lens) should be performed periodically. Lens cleaners are
commercially available. Contact your local CD software
dealer for options.
