• Do not expose discs to direct sunlight or heat 

sources such as hot air ducts, nor leave it in a 
car parked in direct sunlight.

• The unit is not disconnected from the AC 

power source (mains) as long as it is 
connected to the wall socket, even if the unit 
itself has been turned off.

• 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.

qualified service facility.

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

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.
