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, grasp the plug itself; never pull 
the cord.
• The AC power cord must be changed only at 
a qualified service shop.
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 television, VCR, or tape deck. (If 
the receiver is being used in combination 
with a television, 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. Therefore, we recommend 
using an outdoor antenna.)
• 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 components, be sure 
to turn off and unplug the receiver.
If you encounter color 
irregularity on a nearby TV 
screen
The front speakers, center speaker and the 
subwoofers are 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 surround and 
surround back speakers are not magnetically 
shielded, we recommend that you place them 
slightly further away from a TV set (page 14).
If color irregularity is 
observed...
Turn off the TV set, then turn it on again after 
15 to 30 minutes.
