Maintenance
With
the cassette
removed, and
with
the cassette
lid
up, press
down
the
PLAY
key, exposing the
erase
and
record
heads
and
the rubber
drive
wheel. Clean
these points, using a
cotton
swab
moistened
with denatured alcohol (not
nibbing
alcohol) or with
a special
head
cleaning
fluid.
(Your
local
Radio
Shack
store
has
these items,)
To
insure
good
recording
and playback
results,
clean
after
the
first
6 hours of operation (and
every 6-8
hours
of
operation
after that).
After
cleaning,
be
sure to press (he
STOP/EJECT
key, so that
these parts
may
return to
their
normal
operating position
for cassette
hold-
ing.
For
easy
cleaning,
we recommend
our
Cassette
Head
Cleaner
Tape
(44-

is
a
good
idea
to
periodically
demagnetize
the tape heads, too.
Use one of
our
Tape Head Demagnetizes,
You
can
clean
and
demagnetize
in
one
simple
operation
just
by
playing
our
Cassette
Demaunetizer
Tape
(44-63
1),
If
you
use the longer, thinner tapes (C-90, C-l 20,
etc.),
it is
absolutely
vital
that
you
keep your
recorder
clean.
Failure to do so
will result
in
poor
tape
handling,
improper
auto-slop function, and
serious tape wrap-ups. Clean
the
tape handling
parts well
and
often.
CAUTION:
Do
not expose the tape
recorder or
a
cassette to
high temperatures
or high
humidity.
Do
not touch
the tape
heads with
screwdrivers or other metal
objects, or
any magnetic
object.
Remove
the batteries
when
the recorder
will
not be used
for
more
than
a
month,
because
battery leakage
may
damage
the
unit.
Don't
leave
weak
or
dead
batteries
in
the recorder.
