On heat emission during use
This unit will become very hot during use. This is not a
malfunction.
The top, sides, and rear of the cabinet will become quite
hot, especially when playing at high volumes. In such
cases, do not touch the cabinet. Touching the cabinet may
cause physical injury or fire.
In addition, do not use this unit in a completely enclosed
cabinet. Place it in a well ventilated location to prevent an
excessive rise in temperature.
On operation
Before connecting other components, be sure to turn off
and unplug the power amplifier.
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 question or problem concerning your
power amplifier, please consult your nearest Sony dealer.
