Maintenance

■ Condensation

Sudden temperature changes, storage or operation in an extremely

humid environment may cause condensation inside the cabinet (CD
pickup, tape heads, 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 (or cassette) in the unit until normal
playback is possible (about 1 hour). Wipe off any condensation on

the transmitter with a soft cloth before operating tine unit.

■ Before transporting the unit

Remove all CDs from the unit. Make sure there is no CD in the disc

tray. Then, set the unit to the power stand-by mode. Carrying the

unit with discs 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 collec­
tion 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.

■ 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
commercia! head/pinch roller cleaner or isopropyl aicohoL

• When cleaning the heads, pinch rollers, etc., unplug the unit

which contains high voltages.

(c) Pinch roller

• After long use, the deck's heads and capstans may become mag­

netized, 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 per­

formed periodically. Lens cleaners are commercially availabie. Con­
tact your local CD software dealer for options.

■ Cleaning the cabinet

Periodically wipe the cabinet with a soft doth 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.
