BEFORE
USING
THIS
UNIT
Be
sure
to
disconnect
the
mains

before
adjusting
the
voltage
selector.
Use
a
minus

screwdriver
to
set
the
voltage
selector
(on
the
bottom
panel)
to
the
voltage
setting
for
the
area
in
which
the
unit
will
be
used.
Note
that
this
unit
will
be
seriously
damaged
if
this
setting
is
not
made
correctly.
(There
is
no

of
this
unit
may
not
correspond
with
the

proceed
as
follows.
The

MAINTENANCE
OF
EXTERNAL
SURFACES
To
clean,
use
a
soft
dry
cloth.
If
the
surfaces
are
extremely
dirty,
use
a
soft
cloth,
dipped
into
a
soap
and
water
solution
or
a
weak
detergent
solution.
Wring
the
cloth
well
before
wiping
the
unit.
Wipe
once
again
with
a
soft
dry
cloth.
Never
use
alcohol,
paint
thinner,
benzine,
nor
a
chemically
treated
cloth
to
clean
this
unit.
Such
chemicals
may
damage
the
finish
of
your
unit.

FOR
SAFE
USE
OF
THIS
UNIT
■
Use
a
standard
electrical
AC
wall
outlet
1.
Use
from
an
AC
power
source
of
high
voltage,
such
as
for
air
conditioners,
is
very
dangerous.
Be
extremely
careful
not
to
make
a
connection
to
the
electrical
outlet
for
a
large
air
conditioner
or
central-heating
unit
which
uses
high
voltage,
because
there
is
the
possibility
of
fire.
2.
A
DC
power
source
cannot
be
used.
Be
sure
to
check
the
power
source
carefully,
especially
on
a
ship
or
other
place
where
DC
is
used.
■
Connection
and
removal
of
the
power
cord
plug
1.
Wet
hands
are
dangerous.
A
dangerous
electric
shock
may
result
if
the
plug
is
touched
by
wet
hands.
2.
Don't
pull
the
power
cord.
Always
grasp
the
plug;
never
pull
the
cord
itself.
■
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
accidently
touched.
■
For
families
with
children
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.
■
Turn
off
after
use
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
unexpected
trouble.
■
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.
■
Place
the
unit
where
it
will
be
well
ventilated,
and
away
from
direct
sunlight
Place
this
unit
at
least
10
cm
(4")
away
from
wall
surfaces,
etc.,
and
away
from
direct
sunlight.
Be
careful
that
curtains
and
similar
materials
do
not
obstruct
the
ventilation
holes.
■
Keep
the
unit
away
from
heaters,
etc.
Heat
can
damage
the
external
surfaces
as
well
as
internal
circuits
and
components.
■
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.
■
Never
use
alcohol
or
paint
thinner
These
and
similar
chemicals
should
never
be
used,
because
they
may
damage
the
finish.
■
If
trouble
occurs
If,
during
operation,
the
sound
is
interrupted
or
indicators
no
longer
illuminate,
or
if
abnormal
odor
or
smoke
is
detected,
immediately
disconnect
the
power
cord
plug,
and
contact
your
dealer
or
an
Authorized
Service
Center.

PROTECTION
CIRCUITRY
The
protection
circuitry
may
have
operated
if
either
of
the
following
conditions
is
noticed:
•
No
sound
is
heard
when
the
power
is
turned
on.
•
Sound
stops
during
a
performance.
The
function
of
this
circuitry
is
to
prevent
circuitry
damage
if,
for
example,
the
positive
and
negative
speaker
connection
wires
are
"shorted",
or
if
speaker
systems
with
an
impedance
less
than
the
indicated
rated
impedance
of
this
unit
is
used.
If
this
occurs,
follow
the
procedure
outlined
below:
1.
Turn
off
the
power.
2.
Determine
the
cause
of
the
problem
and
correct
it.
3.
Turn
on
the
power
once
again.
Note:
When
the
protection
circuitry
functions,
the
unit
will
not
operate
unless
the
power
is
first
turned
off
and
then
on
again.
