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 insecticides on the unit.
