Precautions
On safety
• Caution – The use of optical instruments
with this product will increase eye hazard.
• 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.
• Do not put any foreign objects in the DC IN
10.5 V (external power input) jack.
On power sources
• Use only the supplied AC power adaptor.
Do not use any other AC power adaptor. It
may cause a malfunction.
• If the AC power adaptor causes interference
to the radio reception, move it away from
the radio.
• Do not touch the AC power adaptor with
wet hands.
• 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.
• Use a commercially available AC plug
adaptor, if necessary, depending on the
design of the wall outlet.
On placement
• Place the player in a location with adequate
ventilation to prevent heat build-up in the
player.
• Do not place the player and the AC power
adaptor on a soft surface such as a rug.
• Do not place the player and the AC power
adaptor in a location near heat sources, or in
a place subject to direct sunlight, excessive
dust, or mechanical shock.
• Do not put any object on top of the player.
The player may be damaged.
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.
• Do not insert a disc with non-standard
shape (e.g., card, heart) into the player. The
disc may not be ejected and cause a
malfunction.
• 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.
If you have any questions or problems
concerning your player, please consult your
nearest Sony dealer.
