On safety
• Caution – The use of optical instruments 

with this product will increase eye hazard.

• To prevent fire or shock hazard, do not 

place objects filled with liquids, such as 
vases, on the apparatus.

• Should any solid object or liquid fall into 

the cabinet, unplug the player and have it 
checked by qualified personnel before 
operating it any further.

On power sources
• The player is not disconnected from the AC 

power source as long as it is connected to 
the wall outlet, even if the player itself has 
been turned off.

• If you are not going to use the player for a 

long time, be sure to disconnect the player 
from the wall outlet. To disconnect the AC 
power cord, grasp the plug itself; never pull 
the cord.

• Should the AC power cord need to be 

changed, have it done at a qualified service 
shop only.

On placement
• Place the player in a location with adequate 

ventilation to prevent heat build-up in the 
player.

• Do not place the player on a soft surface 

such as a rug that might block the 
ventilation holes.

• Do not place the player in a location near 

heat sources, or in a place subject to direct 
sunlight, excessive dust, or mechanical 
shock.

• Do not install the player in an inclined 

position. It is designed to be operated in a 
horizontal position only.

• Keep the player away from equipment with 

strong magnets, such as microwave ovens, 
or large loudspeakers.

• Do not place heavy objects on the player.

On operation
• If the player is brought directly from a cold 

to a warm location, or is placed in a very 
damp room, moisture may condense on the 
lenses inside the player. Should this occur, 
the player may not operate properly. In this 
case, remove the disc and leave the player 
turned on for about half an hour until the 
moisture evaporates.

• When you move the player, take out any 

discs. If you don’t, the disc may be 
damaged.

On adjusting volume
Do not turn up the volume while listening to 
a section with very low level inputs or no 
audio signals. If you do, the speakers may be 
damaged when a peak level section is played.

On cleaning
Clean the cabinet, panel, and controls 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 alcohol or benzine.

On cleaning discs
Do not use a commercially available cleaning 
disc. It may cause a malfunction.

If you have any questions or problems 
concerning your player, please consult your 
nearest Sony dealer.
