Notes on discs
• Before playing, wipe the disc with a cleaning cloth from the centre out to
the edge.
• Do not clean discs with solvents, such as benzine thinner, or commer-
cially available cleaners or anti-static spray intended for vinyl LPs.
• Do not expose discs to direct sunlight or heat sources such as hot air
ducts, nor leave it in a car parked in direct sunlight.
• Do not use a commercial cleaning disc as it may cause the unit to mal-
function.
On safety
• Completely disconnect the power cord (mains lead) from the wall outlet

(mains) if it is not going to be used for an extended period of time. When
unplugging the unit, always grip the plug. Never pull the cord itself.
• Should any solid object or liquid get into the system, unplug the system,
and have it checked by qualifi ed personnel before operating it again.
• AC power cord must be changed only at the qualifi ed service shop.
On placement
• Do not place the system in an inclined position or in locations that are ex-
tremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation,
or subject to vibration, direct sunlight or a bright light.
• Be careful when placing the unit or speakers on surfaces that have been
specially treated (for example, with wax, oil, polish) as staining or discol-
oration of the surface may result.
• 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 lens inside
the CD player, and cause the system to malfunction. In this situation,
remove the disc, and leave the system turned on for about an hour until
the moisture evaporates.
On heat buildup
• Heat buildup on the unit during operation is normal and is not cause for
alarm.
• Do not touch the cabinet if it has been used continuously at a high volume
because the cabinet may have become hot.
• Do not obstruct the ventilation holes.
On the speaker system
This speaker system is not magnetically shielded, and the picture on nearby
TV sets may become magnetically distorted. In this situation, turn off the
TV, wait 15 to 30 minutes, and turn it back on. If there is no improvement,
move the speakers far away from the TV.

On volume adjustment
CDs reproduce sound with considerably less noise than vinyl records. For
this reason, if you raise the volume while listening to a segment containing
only noise (as you might do in the case of a vinyl record), a sudden output
.
of highvolume sound may cause damage to the speakers.
Make sure to lower the volume before the start of playback.

Consideration for others
Keep the volume at a moderate level out of consideration of your neigh-
bors, especially at night.
About the Hard Disk Drive
Because of its high storage density, the hard disk drive can read and write
data a very high speeds. It is, however, easily damaged by mechanical vi-
bration, shock, or dust. Although the hard disk drive is equipped with safe-
ty mechanisms to prevent the lost of data due to these factors, the following
precautions should be taken during the handling of the system.
• Do not subject the system to strong shocks or vibrations.
• Do not place the system in a location subject to mechanical vibration or
at an unstable location.
• Do not move the system while the power cord is connected to a wall
outlet.
• Do not disconnect the power cord while the system is recording or play-
ing a track.
• Do not use the system in a place subject to extreme changes in tempera-
ture (a temperature gradient greater than 18°F (10°C)/hour).
• Do not attempt to replace or upgrade the hard disk drive by yourself, as
this may cause the system to malfunction.
Sony cannot provide compensation for any loss of data caused by a dam-
aged hard disk drive.
Note on the power cord
Before you unplug the power cord from the wall outlet, make sure that the
system is turned off. If you unplug the power cord while the system is oper-
ating, data that was recorded may be lost or the system may malfunction.
Cleaning the cabinet
Clean this system 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 thinner, benzine, or alcohol.
