PRECAUTIONS
@ When replacing the fuse(s), the replacement must be of the same amperage as
shown
on
the
fuse
holder.
If
the
fuse(s)
blows
more
than
once,
carefully
check
all
electrical
connections
for
shorted
circuitry.
Also
have
you
vehicle’s
voltage

checked.
Do
not
attempt
to
repair
the
unit
yourself.
Return
it
to
your
Alpine
dealer
or
the nearest Alpine Service Station for servicing.
@
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
cassette
by
inserting
a
pencil
or
a
similar
instrument
into
the
spindle
hole
and
turn
until
all
the
slack
has
been
taken
up.
