serted properly.

The remote control is being operated
from an incorrect distance or angle.

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 be-
come 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.
