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.
• When transporting the player, press OPEN then remove all
the discs from the player and turn the power off.
If you have any questions or problems concerning your
player, please consult your nearest Sony dealer.
Notes on CDs
On power sources
• Before operating the player, check that the operating
voltage of the player is identical with your local power
supply. The operating voltage is indicated on the nameplate
at the rear of the player.
• The player is not disconnected from the AC power source
(mains) 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 (mains lead), grasp the plug
itself; never pull the cord.
• AC power cord must be changed only at the qualified
service shop.
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 on the bottom.
• Do not place the player in a location near heat sources, or in
a place subject to direct sunlight, excessive dust or
mechanical shock.
On handling CDs
• To keep the disc clean, handle the disc carefully.
• Do not stick paper or tape on the disc.
• Do not expose the disc to direct sunlight or heat sources
such as hot air ducts, nor leave it in a car parked in direct
sunlight as there can be considerable rise in temperature
inside the car.
• After removing a disc from the disc slot, store the disc in its
case.
On cleaning
• Before playing, clean the disc with a cleaning cloth. Wipe
the disc from the center out.
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, leave the
player turned on for about an hour until the moisture
evaporates.
On adjusting volume
• Do not turn up the volume while listening to a portion with
very low level inputs or no audio signals. If you do, the
speakers may be damaged when a peak level portion 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.
16
• Do not use solvents such as benzine, thinner, commercially
available cleaners or anti-static spray intended for vinyl
LPs.
