Sony MHC-V90DW Operating Instructions Manual page 83

On safety
Completely disconnect the AC 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 system, 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 qualified personnel
before operating it again.
AC power cord (mains lead) must be
• •
changed only at the qualified service
shop.
On placement
Do not place the system in an inclined
• •
position or in locations that are
extremely 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 system
on surfaces that have been specially
treated (for example, wax, oil, polish) as
staining or discoloration 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 unit,
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 a 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
The built-in 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
system far away from the TV.
IMPORTANT NOTICE
Caution: If you leave a still video
image or on-screen display image
displayed on your TV for an extended
period of time via this system, you
risk permanent damage to your TV
screen. Projection TVs are especially
susceptible to this.
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.
