To obtain a better bass reproduction, we 
recommend you to place the sub woofer on a 
solid floor where resonance is unlikely to occur.

• Always place the sub woofer vertically, keeping it a 

few centimeters away from the wall.

• If the sub woofer is placed in the center of a room, the 

bass could be extremely weakened. This is due to the 
influence of the standing wave of the room. If this 
happens, move the sub woofer away from the center 
of the room or eliminate the cause of the standing 
wave, by placing a bookshelf against the wall, etc.

Perform the following procedure to protect 
the CD mechanism. Use buttons on the unit 
for the operation.

Make sure that all discs are removed 
from the system.

Hold down CD and then press 

?/1

 until 

“STANDBY” appears.

After a few seconds later, “STANDBY” 
disappears and “LOCK” appears.

Unplug the power cord.
