Maintenance
■ Cleaning the tape-handling ■ Cleaning the cabinet
Periodically wipe the cabinet with a soft cloth
parts
● 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 magnetised, causing poor
sound. Demagnetise these parts once every 30 hours of playing/recording by using a
commercial tape head demagnetiser. Read
the demagnetiser’s instructions carefully before use.
