Suggestions
for
Safety
■
Use
a
standard
AC
wall

1.
Um
ot
an
AC
powar
aourca
of
high
voltage,
such
as
for
an
air
conditioner,
la
vary
dangerous.
There
Is
the
possibility
that
a
fire
might
be
caused
by
making
such
a
connection.
2.
A
DC
powar
source
cannot
be
used.
Be
sure
to
check
the
power
source
carefully,
especially
on
a
ship
or
other
place
where
DC
is
used.
■
Grasp
the
plug
when
disconnecting
the
power
supply
cord
1.
Wet
hands
are
dangerous.
A
dangerous
electric
shock
may
result
if
the
plug
is
touched
by
wet
hands.
2.
Never
place
heavy
Items
on
top
of
the
power
supply
cord,
and
never
force
It
to
bend
sharply.
■
Place
the
unit
where
It
will
be
well
ventilated
Place
this
unit
at
least
10
cm
(4")
away
from
wall
surfaces,
etc.
Be
careful
that
curtains
and
similar
materials
do
not
obstruct
the
ventilation
holes.
■
Take
particular
care
if
children
are
present
Never
permit
children
to
put
anything,
especially
metal,
inside
this
unit.
A
serious
electric
shock
or
malfunction
could
occur
If
articles
such
as
coins,
needles,
screwdrivers,
etc.
are
inserted
through
the
ventilation
holes,
etc.
of
this
unit.
■
If
water
is
spilled
on
the
unit
Be
extremely
careful
if
water
is
spilled
on
the
unit,
because
a
fire
or
serious
electric
shock
might
occur.
Immediately
disconnect
the
power
cord
plug,
and
consult
with
your
dealer.
■
Avoid
spray-type
insecticides
Insecticides
might
cause
cracks
or
“cloudiness”
in
the
cabinet
and
plastic
parts
of
this
unit.
The
gas
used
in
such
sprays
might,
moreover,
be
ignited
suddenly.
■
Avoid
places
such
as
the
following:
In
direct
sunlight
or
In
other
places
where
the
temperature
Is
high.
in
places
where
there
la
excessive
vibration
or
humidity.
Such
conditions
might
damage
the
cabinet
and/or
other
compo¬
nent
parts
and
thereby
shorten
the
unit’s
service
life.
■
Be
sure
to
place
the
unit
on
a
flat,
level
sur¬
face.
if
the
surface
Is
inclined,
a
malfunction
may
result.
■
Never
use
alcohol
or
paint
thinner
These
and
similar
chemicals
should
never
be
used,
because
they
might
cause
flaking
or
cloudiness
of
the
cabinet
finish.
■
Disconnect
the
power
supply
cord
If
the
unit
will
not
be
used
for
a
long
time
if
the
unit
is
left
for
a
long
time
with
the
power
ON,
this
will
not
only
shorten
its
useful
operation
life,
but
may
also
cause
other
troubles.
■
Never
attempt
to
repair
or
reconstruct
this
unit
A
serious
electric
shock
might
occur
if
this
unit
Is
repaired,
disassembled
or
reconstructed
by
unauthorized
persons,
or
if
the
internal
parts
are
accidentally
touched.
■
If
trouble
occurs
If,
during
operation,
the
sound
is
interrupted
or
indicators
no
longer
illuminate,
or
if
abnormal
odor
or
smoke
is
detected,
im¬
mediately
disconnect

and
contact
your
dealer
or
an
