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.
Cleaning the CD pickup lens
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 chemicals for cleaning (gasoline, paint thinner, etc.). It
may damage the cabinet finish.
Do not apply oil to the inside of the unit. It may cause
malfunctions.
