Maintenance
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 be-
come magnetised, causing poor sound. Demagenetise
these parts once every 30 hours of playing/recording time
by using a commercial tape head demagnetiser. Read the
demagnetiser’s instructions carefully before use.
Clean the dust or stain on the CD pickup lens using a com-
mercial cleaning disc (brush type).
