Precautions
• The power requirements and power
consumption of this player are indicated on
the back of the player. Check that the
player’s operating voltage is identical with
your local power supply.
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.
For the model supplied with the AC plug
adaptor
If the AC plug of your unit does not fit into
the wall autlet, attach the supplied AC plug
adaptor.
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.
