1) USE AN ORDINARY HO
SOURCE
USEHOLD AC POWER
Wi 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.
Mi A DC power source cannot be used.
Be
sure
to
check
the
power
source
carefully,
especially
ona
ship
or
other
place
where
DC
is
used.
2) CONNECTION AND DISCONNECTION OF THE ©
POWER CORD PLUG |
Wi Wet hands are dangerous.
A
dangerous
electric
shock
may
result
if
the
plug
is
touched
by
wet
hands.
Hi Don’t pull the power cord.
Always grasp the plug; never pull the cord itself.
3) AC OUTLETS ON REAR PANEL
HE Any equipment connected here should have
specified power consumption or less.
These
outlets
are
exclusively
for
the
connection
of
other
audio
equipment,
such
as
a
tape
deck.
Be
sure
the
power
consumption of each does not exceed wattage specified
near the AC outlets.
Wi
Never
connect
other
electrical
appliances
such
as
an
iron
or
toaster.
If appliances with a large power consumption are con-
nected, an unexpected accident might occur as a result
of overheating.
4)
NEVER
ATTEMPT
TO
REPAIR
OR
RECON-
STRUCT
THIS
UNIT
ss
|
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.
5) 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,
screw-
drivers,
etc.
are
inserted
through
the
ventilation
holes,
etc.
of
this
unit.
6) TURN OFF AFTER USE
lf
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.
7) 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.
8) 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.
9) KEEP THE UNIT AWAY FROM STOVES, ETC.
Heat can damage the external surfaces as well as internal
circuits and components.
10) 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.
11) NEVER USE ALCOHOL OR PAINT THINNER
These and similar chemicals should never be used, be-
cause they may damage the finish.
‘IF TROUBLE OCCURS
If, during operation, the sound is interrupted or indication
lamps 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.
1) This unit employs unique automatic speaker-imped-
ance-comparator circuitry to deliver optimum amplifier-
power output at the following recommended speaker
loads.
eMAIN or REMOTE: 4 ohms or greater
*MAIN + REMOTE: 8 ohms or greater
2) Only one set of speakers should be connected to each
speaker terminal at one time,and external accessories
such as a switching device, monitors, etc. should not be
connected as this will defeat the function of the circuit,
causing possible fire or electric shock due to excessive
temperature.
3) During initial set-up or when changing speakers, be sure
to set the speaker selectors@ or power switch® to the
“OFF” position first and then make the necessary con-
nections. Check for proper polarity and then set the
speaker selectors@ or power switch@ to the ‘‘ON”
position. It is important that this sequence be observed
for the proper operation of the automatic speaker-
impedance-comparator circuitry.

If an abnormal condition is detected in the output circuitry,
the protection circuitry will function, and this indicator will
no longer illuminate. if this occurs, turn off the power
switch@, and check to determine the trouble, as described
below.
Release the speaker selectors@ to the off position (m-~— BL),
and turn on the power switch@®.
1) If the indicator then illuminates
The problem is not in this unit.
Check for probable causes, such as a shorted plus (®)
and minus (©) speaker connection terminals or impro-
per impedance of the speaker systems.
Note concerning speaker impedance:
lf main and remote speaker systems are used at the
same time, their impedance should be 8 or more. If
only the main or the remote are to be used separately,
their impedance should be 42 or more.
2) If the indicator still does not illuminate
The problem is in this unit. Turn off the power switch@,
and request your dealer to inspect and repair it.
