4.1.2 Demagnetization
Before any alignment work and in intervals of every few
weeks, the cassette recorder should be demagnetized.
Switch the cassette recorder off, make sure that no cas-
sette is in the compartment and that no cassettes are lo-
cated in the vicinity of the recorder. Slowly approach but
do not contact the part to be demagnetized with the tip of
the choke and after a short moment slowly retract the
choke; or with a regulating transformer slowly increase
the choke voltage to maximum and back to minimum.
This procedure is to be performed for all metal parts
(sound heads, tape guides) that come in contact with the
tape. Before you switch off the choke remove it at least
50 cm from the cassette recorder.
