DEMAGNETIZING THE HEAD
The head becomes magnetized when you use the tape deck for
prolonged periods of time. This results in noise being generated
and the treble dropping off during recording and piayback. The
head should therefore be demagnetized
regularly with a head
demagnetizer
(sold separately}. For further details, refer to the
operating instructions accompanying your head demagnetizer.
NOTE:
* Do not hold screwdrivers, metal objects, or magnets close to
the heads.
« When demagnetizing
the heads, be sure the unit's POWER
switch is to the standby position.
