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.

Pinch rollers
After long use, the deck's heads and capstans 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 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 CD pickup lens
Poor performance during CD playback (skipping or jumping) can be
caused by a dirty or contaminated CD laser pick up lens. If this
happens then the use of a commercially available CD lens cleaning
discs may restore normal operation. Contact your supplier or local
CD software dealer to obtain CD lens cleaning discs. Ensure all
included instructions/documentation are carefully followed.
