Precautions
On safety
• Operate the stereo system only on 120 V AC, 60 Hz.
• Unplug the stereo system from the wall outlet if it is not to
be used for an extended period of time. To disconnect the
cord, pull it out by grasping the plug. Never pull the plug out
by the cord.
• Do not place anything on top of the amplifier. The
ventilation holes must be unobstructed for the proper
operation of the unit and to prolong the life of its
components.
• Should any liquid or solid object fall into the unit, unplug
the stereo system, and have the unit checked by qualified
personnel before operating it any further. For repairs, take
in all the components together, even if only one needs
repairing.
On installation
• Avoid installing or leaving the stereo system in a location:
— near heat sources such as radiators, airducts or heaters
subject to direct sunlight
— exposed to rain or moisture
— where it is liable to come into contact with dust or dirt
— that is unventilated, such as a bookcase
If you have any question or problem concerning your stereo
system that is not covered in this manual, please consult
your nearest Sony dealer.
