VOLTAGE ADJUSTMENT (Refer to fig. 1.)
Before
connecting
this
unit
to
the
AC
outlet,
make
sure
that
it
is
properly
set
to
your
local
voltage.
This
unit
has
been
set
to
operate
on
the

ABOUT CASSETTE TAPE (Refer to fig. 2.)
The cassette tape used in this unit Is the type universal throughout
the world.
Notes:
1. Never attempt to pull the tape out of the cassette openings.
2. Never try to turn the reels of the tape cassette by hand because to
do so may loosen the tape. If the tape is loose in the cassette, the
tape may become wound onto the pressure roller and result in
breakage or damage. Tighten looseness of the tape, if necessary,
by using a pencil as shown in the figure.
3. Avoid using C-120 cassette tape with this unit because this tape
can easily become broken, stretched or twisted if not used with
extreme care.
4. Avoid storing this unit in places where the temperature is high
and/or where the humidity is high.
5. If the tape is very tightly wound or unevenly wound, fast forward
it and then rewind it before use.
ACCIDENTAL ERASE PREVENTION
(Refer to fig. 3.)
Tape
cassettes
have
special
plastic
tabs,
one
each
for
side
one
and
side
two,
which,
if
removed,
prevent
accidental
erasure
of
recorded
material.
These
tabs
can
be
pushed
out
with
a
screwdriver
or
similar
tool.
If
they
are
pushed
out,
note
that,
for
this
unit,
the
RECORD
button
cannot
be
pushed.
If,
for
any
reason,
it
is
later
desired
to
make
a
recording
on
a
cassette
from
which
the
tabs
have
been
pushed
out,
it
is
possi-
ble
to
do
so
by
simply
covering
the
holes
where
the
tabs
were
with
cellophane
tape
and
recording
in
the
usual
way.
