Before transporting the unit
Remove the iPod and the disc from the unit. Then, set the unit to the
power stand-by mode. Carrying the unit with iPod left docked might
damage both the unit and the iPod.
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 center, along the radius.

Maintenance
Cleaning the tape-handling parts
Dirty heads, capstans or pinch rollers can cause poor sound and
tape jams. Clean these parts with a cotton swab moistened with
commercial head/pinch roller cleaner or isopropyl alcohol.
When cleaning the heads, pinch rollers, etc., unplug the unit which
contains high voltages.

After long use, the deck's heads and capstans may become
magnetized, causing poor sound. Demagnetize these parts once
every 30 hours of playing/recording time by using a commercial
tape head demagnetizer. Read the demagnetizer's instructions
carefully before use.
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.
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 finish.
Do not apply oil to the inside of the unit. It may cause
malfunctions.
