MAINTENANCE
■Internal care
●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.
● 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.
■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.
