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.
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 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.
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.
