Maintenance

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 magnetized, 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.
In order to ensure proper operation of the CD player, preventative maintenance
(cleaning of the laser pickup lens) should be performed periodically.
Lens cleaners are commercially available. Contact your local CD software dealer
for options.
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 oil, solvents, gasoline, paint thinners or insecti-
cides on the unit.
