A DualDisc is a two sided disc product which mates 

DVD recorded material on one side with digital 

audio material on the other side. However, since the 

audio material side does not conform to the Compact 

Disc (CD) standard, playback on this product is not 

guaranteed.

This product is designed to playback discs that conform 

to the Compact Disc (CD) standard. Recently, various 

music discs encoded with copyright protection 

technologies are marketed by some record companies. 

Please be aware that among those discs, there are some 

that do not conform to the CD standard and may not be 

playable by this product.



 Completely disconnect the power cord (mains lead) 

from the wall socket (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.



 The AC power cord can be changed only by a qualified 

service facility.



 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 CD player, 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.



 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.

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.

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.
