MAINTENANCE
■ Internal care
● Do not touch the Laser pickup lens. If fingerprints
or dust accumulate on the pickup, clean it gently
with a dry cotton swab.
● Dirty heads, capstan or pinch roller can cause
poor sound and tape jams. Clean these parts
with a cotton swab moistened with commercial
head/pinch roller cleaner or isopropyl alcohol.
● After long use, the deck’s heads and capstan
may become magnetized, causing poor sound.
Demagnetize these parts once every 30 hours
of playing/recording by using a commercial tape
head demagnetizer. Read the demagnetizer’s
instructions carefully before use.
■ External care
● Periodically wipe the cabinet with a soft cloth and
a diluted soap solution, then wipe with a dry
cloth.
● Do not use chemically treated cleaning cloths or
other chemicals.
