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 magnetised, causing
poor sound. Demagnetise 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.

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 (petrol, paint thinner,
etc.). It may damage the cabinet finish.


Do not apply oil to the inside of the unit. It may cause
malfunctions.
