HEAD
DEMAGNETIZING
The
tape
heads,
capstan
and
tape
guides
gradually
become
magnetized
with
use,
which
will
eventually
affect
the
sound
quality
of
your
tapes
Demagnetizing
should
follow
cleaning,
but
need
not
take
place
as
often
as
cleaning,
once
after
every
20
to
30
hours
of
use
should
suffice.
A
demagnetizer
may
be
purchased
at
a
moderate
cost
from
any
dealer
carrying
tape
recording
accessories.
Follow
the
instruction
supplied
with
the
demagnetizer.
Caution:
Be
sure
to
turn
off
the
unit
before
you
attempt
demagnetizing.
