! 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 mag-
netised, 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 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 hap-
pens 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.
! 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 malfunc-
tions.
