I 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
H
Periodically wipe the cabinet with a soft cloth and a diluted soap solution, then
with a dry cloth.
Caution:
I Do not use chemicals for cleaning (petrol, paint thinner, etc.). It may damage
the cabinet finish.
I Do not apply oil to the inside of the unit. It may cause malfunctions.
