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 qualified personnel before
operating it again.
• AC power cord must be changed only at the
qualified service shop.
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 unit or speakers
on surfaces that have been specially treated
(for example, with wax, oil, polish) as staining
or discoloration of the surface may result.
• If the system is brought directly from a cold to
a warm location or is placed in a very damp
room, moisture may condense on the lens
inside the unit, and cause the system to
malfunction. In this situation, remove the
disc, and leave the system turned on for about
an hour until the moisture evaporates.
On heat buildup
• Heat buildup on the unit during operation is
normal and is not a 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
This speaker system is not magnetically
shielded, and the picture on nearby TV sets may
become magnetically distorted. In this situation,
turn off the TV, wait 15 to 30 minutes, and turn
it back on. If there is no improvement, move the
speakers far away from the TV.
Cleaning the cabinet
Clean this system 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 thinner, benzine,
or alcohol.
