When the heads, capstans and pinch rollers become dirty, this
may result in muffled, distorted or reduced sound during play-
back and may even result in tape jams.
Open the cassette compartment door and clean with a cotton
swab moistened with a commercially sold head/pinch roller
cleaner or alcohol.
@ Wait approximately 10 seconds for the alcohol or cleaning
fluid to dry before using.
If the heads are used for a tong time, the
heads will gradually become magnetised.
@ Read the instructions that come with
the demagnetiser carefully on use.
When the heads become magnetised:
© Treble tones may be lost and distortion may result during playback.
@ Static distortions may be recorded along with recordings.
® Distortion and noise may be recorded on previously recorded music tapes.
Any of the above may occur.

To clean the. cabinet or panel, wipe with a soft cloth and a
dilute soap solution,
Then wipe with a dry cloth.
Do not use a chemically treated cleaning cloth, benzine or
paint thinner,
This will cause the cabinet material to change chemically and
result in cracking, peeling or damage to the finish.
