On power sources
 Unplug the unit from the wall outlet if you do not 
intend to use it for an extended period of time. To 
disconnect the cord, pull it out by the plug, never by 
the cord.
On placement
 Place the system in a location with adequate 
ventilation to prevent heat build-up in the system.
 At high volume, over long periods of time, the cabinet 
becomes hot to the touch. This is not a malfunction. 
However, touching the cabinet should be avoided. Do 
not place the unit in a confined space where 
ventilation is poor as this may cause overheating.
 Do not block the ventilation slots by putting anything 
on the system. The system is equipped with a high 
power amplifier. If the ventilation slots are blocked, 
the unit can overheat and malfunction.
 Do not place the unit on surfaces (rugs, blankets, etc.) 
or near materials (curtains, draperies) that may block 
the ventilation slots.
 Do not install the unit near heat sources such as 
radiators, or air ducts, or in a place subject to direct 
sunlight, excessive dust, mechanical vibration, or 
shock.
 Do not install the unit in an inclined position. It is 
designed to be operated in a horizontal position only.
 Keep the unit and discs away from equipment with 
strong magnets, such as microwave ovens, or large 
loudspeakers.
 Do not place heavy objects on the unit.
On operation
 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 lenses inside the control unit. 
Should this occur, the system may not operate 
properly. In this case, remove the disc and leave the 
system turned on for about half an hour until the 
moisture evaporates.
 When you move the system, take out any disc. If you 
don’t, the disc may be damaged.
 If anything falls into the cabinet, unplug the unit and 
have it checked by qualified personnel before 
operating it any further.
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 suddenly 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.
If you have any questions or problems concerning 
your system, please consult your nearest Sony dealer.
On cleaning discs, disc/lens 
cleaners
• Do not use cleaning discs or disc/lens cleaners 
(including wet or spray types). These may cause 
the apparatus to malfunction.
On your TV’s color
 If the speakers should cause the TV screen to have 
color irregularity, turn off the TV then turn it on after 
15 to 30 minutes. If color irregularity should persist, 
place the speakers further away from the TV set.
On moving the system
Before moving the system, make sure that there is no 
disc inserted, and remove the AC power cord (mains 
lead) from the wall outlet (mains).

 If the picture output from your system goes 
through your VCR to get to your TV, the copy-
protection signal applied to some DVD programs 
could affect picture quality. If you still experience 
problems even when you connect your unit 
directly to your TV, try connecting your unit to 
your TV’s S video input (page 19).
Even though you set the aspect ratio in [TV 
TYPE] of [SCREEN SETUP], the picture does 
not fill the TV screen.
 The aspect ratio on the disc is fixed.
Color irregularity occurs on the TV screen.
The subwoofer and the front speakers in this system 
are magnetically shielded to prevent magnetic 
leakage. However, some leakage may occur, as a 
high-strength magnet is employed. If this happens,
