Precautions

On safety
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.
On power sources
• Before operating the receiver, check that
the operating voltage is identical with
your local power supply.
The operating voltage is indicated on the
nameplate on the back 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 (mains
lead), grasp the plug itself; never pull the
cord.
• The AC power cord (mains lead) must be
changed only at a qualified service shop.
For the model supplied with
the AC plug adaptor
If the AC plug of your receiver does not fit
into the wall outlet, attach the supplied AC
plug adaptor.
On heat buildup
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 considerably. To
avoid burning yourself, do not touch the
cabinet.

On placement
• Place the receiver in a location with
adequate ventilation to prevent heat
buildup and prolong the life of the
receiver.
• 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.
• Do not place the receiver near equipment
such as a TV, VCR, or tape deck. (If the
receiver is being used in combination
with a TV, VCR, or tape deck, and is
placed too close to that equipment, noise
may result, and picture quality may
suffer. This is especially likely when
using an indoor antenna (aerial).
Therefore, we recommend using an
outdoor antenna (aerial).)
• Use caution when placing the receiver or
speakers on surfaces that have been
specially treated (with wax, oil, polish,
etc.) as staining or discoloration of the
surface may result.
On operation
Before connecting other equipment, be sure
to turn off and unplug the receiver.
If you encounter color
irregularity on a nearby TV
screen
The center speaker is magnetically shielded
to allow it to be installed near a TV set.
However, color irregularities may still be
observed on certain types of TV sets. As
the front speakers, surround/surround back
speakers and the subwoofers are not
magnetically shielded, we recommend that
you place them slightly further away from
a TV set (page 15).
If color irregularity is
observed...
Turn off the TV set, then turn it on again
after 15 to 30 minutes.
