Precautions
On safety
© Operate the unit only on 120 V AC, 60 Hz.
¢ Should any solid object or liquid fall into the unit, unplug
it and have it checked by qualified personne! before
operating it any further.
e Unplug the unit 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 cord itself.
On installation
© Place the unit on a level surface.
Do not install the unit in a location near heat sources such
as radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or shock.
© Good air circulation is essential to prevent internal heat
buildup in the unit. Place the unit in a location with
adequate air circulation. Do not piace the unit on a soft
surface, such as a rug that would block the ventilation
holes on the bottom.
© Do not place anything on top of the cabinet. The top
ventilation holes must be unobstructed for the proper
operation of the unit and to prolong the life of its
components.
On cleaning the cabinet
Clean the cabinet, panel and controts with a soft cloth
lightly moistened with mild detergent solution. Do not use
any type of abrasive pad, scouring powder or solvent such
as alcohol or benzine.
On repacking
Do not throw away the carton and the packing material. It
makes an ideal container to transport the unit in.
If you have any question or problem concerning your unit,
please consult your nearest Sony dealer.
For detailed precautions, see the leaflet "IMPORTANT
