• Internal care

• Dirty heads, capstans and pinch rollers cause poor sound
and tape jams. Clean these parts with cotton swab moistened
with commercial head/pinch roller cleaner or isopropyl alchohol.
• After long use, the deck's heads and capstans will become
magnetised, which causes poor sound. Demagnetise these
parts once every 30 hours of playing/recording time by using
commercial tape deck demagnetiser. Read demagnetiser's in-
structions carefully before using.

• External care

• Periodically wipe cabinet clean with soft cloth and dilute
soap solution, then wipe with dry cloth.
• Do not use chemically treated cleaning cloths or other chem-
icals. (See Cautions.)
