About
Cleaning:
When
the
heads
are
dirty
with
dust,
the
tape
deck
not
only
fails
to
faithfully
reproduce
highs
but
there
are
audible
skips
of
sound.
When
the
pinch
roller
and/or
capstan
are
dirty,
the
tape
may
become
entangled
with
them
as
it
travels.
So,
clean
them
periodically
and
especially
before
marking
any
impor
tant
recordings.
The
head,
pinch
roller
and
capstan
can
be
cleaned
comparatively
easily
if
you
clean
them
while
the
Cassette
Holder
is
pushed
in
and
the
(Play
Button)
is
dep
ressed
which
extends
the
heads
for
easy
access,

a
head
and
rubber
cleaner
set
for
this
cleaning
job.
