Precautions
On safety
Completely disconnect the power cord (mains lead) 
from the wall outlet (mains) if it is not going to be used 
for an extended period of time. When unplugging the 
unit, always grip the plug. Never pull the cord itself.
Should any solid object or liquid get into the system, 
unplug the system, and have it checked by qualied 
personnel before operating it again.
e AC power cord can be changed only by a qualied 
service facility.
On placement
Do not place the system in an inclined position or in 
locations that are extremely hot, cold, dusty, dirty, or 
humid or lacking adequate ventilation, or subject to 
vibration, direct sunlight or a bright light.
Be careful when placing the system on surfaces that 
have been specially treated (for example, with wax, oil, 
polish) as staining or discoloration of the surface may 
result.
Condensation may form on outer surfaces or internally, 
and cause the system to malfunction if the system is 
suddenly moved from a cold to a warm environment. If 
condensation forms, turn o the system, and leave the 
system o until the moisture evaporates. Do not use the 
system until the condensation has fully evaporated.
On heat buildup
Heat buildup on the unit during operation is normal 
and is not cause for alarm.
Do not touch the cabinet if it has been used 
continuously at a high volume because the cabinet may 
have become hot. 
Do not obstruct the ventilation holes.
On the speaker system
e built-in speaker system is not magnetically shielded, 
and the picture on nearby TV sets may become 
magnetically distorted. In this situation, turn o the TV, 
wait 15 to 30 minutes, and turn it back on. 
If there is no improvement, move the system far away 
from the TV.
Cleaning the cabinet
Clean this system with a so cloth slightly moistened 
with a mild detergent solution. Do not use any type of 
abrasive pads, scouring powder, or solvents, such as 
thinner, benzine, or alcohol.
