Before transporting the unit
Remove CD from the unit. Make sure there is no CD in the disc
compartment. Then, set the unit to the power stand-by mode.
Carrying the unit with disc left inside can damage the unit.
Care of compact discs
Compact discs are fairly resistant to damage, however mistracking
can occur due to an accumulation of dirt on the disc surface. Follow
the guidelines below for maximum enjoyment from your CD
collection and player.
Do not write on either side of the disc, particularly the non-label
side from which signals are read. Do not mark this surface.
Keep your discs away from direct sunlight, heat, and excessive
moisture.
Always hold the CDs by the edges. Fingerprints, dirt, or water on
the CDs can cause noise or mistracking. If a CD is dirty or does
not play properly, clean it with a soft, dry cloth, wiping straight out
from the centre, along the radius.

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 (petrol, paint thinner, etc.). It
may damage the cabinet finish.
Do not apply oil to the inside of the unit. It may cause
malfunctions.
Cleaning the lens and tape-handling parts
Do not touch the laser pickup lens, if finger prints or dust accumu-
late on the pickup, clean it gently with a dry cotton swab.

jams. Clean these parts with a cotton swab moistened with com-
mercial head/pinch roller cleaner or isopropyl alcohol.
When cleaning the head, pinch roller, etc., unplug the unit which
contains high voltages.
After long use, the deck's head and capstan may become magne-

Correct
