In
order
to
ensure
proper
performance,
be
sure
the
temperature
in
your
vehicle
is
between the range of 14°F (—10°C) to 140°F (60°C) before turning your player on.
Good
air
circulation
is
essential
to
prevent
heat
build-up
in
the
unit
(especially
in
hot
weather).
C-120
type
cassette
tapes
are
not
recommended
for
use
in
automobile
tape
players.
Prevent any foreign objects from entering the cassette opening as the precision
mechanism and tape head may be damaged.
To
protect
your
cassette
tapes,
store
them
in
a
cool
place
away
from
dust,
dirt,
and
strong magnetic sources such as electric motors, speakers and TV sets.
Check
and
make
sure
any
slack
in
the
tape
is
taken
up
before
inserting
the
tape
into
the
unit.
A
loose
tape
could
cause
damage
to
the
unit
and
the
tape
itself.
Tighten
the

will
extinguish.
Then
after
the
lapse
of
25
seconds,
a
rhythmical
alarm
will

to
another
stronger
station.
If
the
reception
of
further
traffic
information
is
required,
tune
in
the
desired
traffic
information
station.
When
received,
the
alarm
will
stop
and
the
SK
indicator
illuminates.
Since
the
alarm
will
continue
if
no
signals
from
any
other
