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 and center speakers and the sub 
woofer 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 speakers are 
not magnetically shielded, we recommend that 
you place the surround speakers slightly 
further away from TV set (page 13).
If color irregularity is 
observed...
Turn off the TV set, then turn it on again after 
15 to 30 minutes.
If color irregularity is observed 
again...
Place the speaker further away from the TV 
set.
If howling occurs
Reposition the speakers or turn down the 
volume on the receiver.
On cleaning
Clean the cabinet, panel, and controls with a 
soft cloth slightly moistened with a mild 
detergent solution. Do not use any type of 
abrasive pad, scouring powder, or solvent, 
such as alcohol or benzine.
If you have any questions or problems 
concerning your receiver, please consult your 
nearest Sony dealer.
