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 unit, 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.
• The AC power cord should be changed only at a
qualified service shop.
On heat buildup
Although the unit heats up during operation, this is not
a malfunction. Further, it is not a malfunction that the
upper left corner of the unit heats up while the power is
on. If you continuously use this unit at a high volume,
the cabinet temperature of the top, sides and bottom
will rise 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
possible mechanical shock.
• Do not place anything on top of the cabinet that
might block the ventilation holes and cause
malfunctions.
• Use caution when placing the unit 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 have any questions or problems concerning your
receiver, please consult your nearest Sony dealer.
