persons.

This symbol is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.

This equipment has been tested and found

interference by one or more of the
following measures:
– Reorient or relocate the receiving

antenna.

guidelines for energy
efficiency.

• Should any solid object or liquid fall into the

cabinet, unplug the receiver and have it
checked by qualified personnel before
operating it any further.

• To prevent fire, do not cover the ventilation

of the receiver with newspapers, table cloths,
curtains, etc. And don’t place lighted candles
on the receiver.

• To prevent fire or shock hazards, do not place

vases on the receiver.

• Before operating the receiver, check that the

operating voltage is identical with your local
power supply. The operating voltage is
indicated on the nameplate at the rear of the
receiver.

• The unit is not disconnected from the AC

power source (mains) as long as it is
connected to the wall outlet, even if the unit
itself has been turned off.

• If you are not going to use the receiver for a

long time, be sure to disconnect the receiver
from the wall outlet. To disconnect the AC
power cord, grasp the plug itself; never pull
the cord.

• One blade of the plug is wider than the other

for the purpose of safety and will fit into the
wall outlet only one way. If you are unable to
insert the plug fully into the outlet, contact
your dealer. (Models of area code U, CA only)

• AC power cord must be changed only at the

qualified service shop.

• Place the receiver and speakers in a location

with adequate ventilation to prevent heat
buildup and prolong the life of the receiver
and speakers.

• Do not place the receiver near heat sources,

or in a place subject to direct sunlight,
excessive dust or mechanical shock.

• Do not place anything on top of the cabinet

that might block the ventilation holes and
cause malfunctions.

• Although the receiver heats up during

operation, this is not a malfunction. If you
continuously use this receiver at a large
volume, the cabinet temperature of the top,
side and bottom rises accordingly. To avoid
burning yourself, do not touch the cabinet.

• Do not place the speakers near heat sources

such as radiators or air ducts, or in a place
subject to direct sunlight, excessive dust,
mechanical vibration or shock.

• Do not place the speakers on a soft surface or

in an inclined position, keeping a few
centimeters away from the wall. To abtain a
better bass reproduction, we recommend you
to install the woofer on a solid floor where
the resonance is unlikely to occur.

• If the woofer is installed in the center of a

room, the bass could be extremely weakened.
This is due to the influence of the standing
wave of the room. If this happened, move the
woofer away from the center of a room or
eliminate the cause of the standing wave, by
installing a bookshelf on the wall, etc.

Before connecting other components, be sure to
turn off and unplug the receiver.

Don’t throw a battery,
dispose it as the injurious
wastes.
