sound quality.
Cannot erase completely.
Sound skipping.
Cannot hear treble.
Sound fluctuation.

dirty?
If a power failure occurs during playback,
the heads remain engaged with the tape.
Do not open the compartment forcibly.
Wait until electricity resumes.
CD player
Symptom
Playback does not start.
Playback stops in the middle or is
not performed properly.
Playback sounds are skipped, or
stopped in the middle of a track.
Possible cause
The disc is loaded up-side down.
The disc does not satisfy the standards.
The disc is distorted or scratched.
Is the unit located near excessive vibra-
tions?
The disc is very dirty.
Has condensation formed inside the
unit?
Condensation
Sudden temperature changes, storage or operation in an extremely humid environ-
ment may cause condensation inside the cabinet (CD pickup, tape heads, etc.) or on
the transmitter light-emitting diode 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 light-
emitting diode with a soft cloth before operating the unit.

Maintenance
Cleaning the tape-handling parts
Dirty heads, capstan or pinch roller 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 roller, etc., unplug the unit which contains high
voltages.

After long use, the deck’s heads and capstan may become magnetised, causing
poor sound. Demagnetise these parts once every 30 hours of playing/recording
time by using a commercial tape head demagnetiser. Read the demagnetiser’s
instructions carefully before use.
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 chemically treated cleaning cloths or other chemicals.

Caution:
This operation will erase all data stored in memory including clock and timer settings,
and tuner and CD presets.
Before transporting the unit
Remove all CDs from the unit. Your unit checks whether there are any discs inside the
unit when the tray is closed. “CD NO DISC” appears if no disc is left. Then, set the unit
to the power stand-by mode. Carrying the unit with discs left inside can damage it.
