INFORMATION

This
technical
information
is
located
on
pp
45-51
of
the

Service
Manual
(Order

Head
demagnetization
In
order
to
maintain
good
sound
quality
during
recording
and
playback,
it
is
recommended
that
the
heads
should
be
demagne-
tized
if
distortion
or
poor
sound
quality
persist
after
cleaning
the
heads.
If
the
heads
become
magnetized,
they
could
create
noise
in
recordings,
loss
of
high-frequency
response,
or
erasure
of
valuable
recordings.
Several
types
of
head
demagnetizers
are
available
and
may
be
purchased
at
local
electronics
supply
stores.
Follow
the
instructions
that
are
supplied
with
the
device.
®Do
not
bring
any
type
of
metal
objects
or
tools
such
as
magnetic
screwdrivers
in
contact
with
the
head
assembly.
