from the AC outlet before cleaning.
• If you rub on the unit with a stained cloth,
the cabinet may be scratched.

such as insecticide, or the unit is in contact
with a rubber or vinyl resin product for a
long period of time, the unit may
deteriorate or the coating may come off.
• Do not touch the lens with bare hands.

Precautions
On Screen
When using a screen with an uneven surface,
stripes pattern may rarely appear on the
screen depending on the distance between
the screen and the unit or the zooming
magnifications. This is not a malfunction of
the unit.
On Fan
Since the projector is equipped with a fan
inside to prevent internal temperature from
rising, there may be some noise. This is a
normal result of the manufacturing process
and does not indicate a malfunction. If,
however, in a case of abnormal noise,
consult with qualified Sony personnel.
On Lamp
The lamp used as a light source contains
mercury that has high internal pressure. A
high-pressure mercury lamp has the
following characteristics:
• Brightness of the lamp will be lowered as
the elapse of time used.
• The lamp may break with a loud noise as a
result of shock, damage, or deterioration
caused by the elapse of time. The lamp
may become unlit and may burn out.
• The lamp life varies with individual
differences or usage conditions of each
lamp. Therefore, it may break or will not
light even before the specified
replacement time.
• It may possibly break after the
replacement time has elapsed. Replace the
lamp with a new one as soon as possible if
a message displayed on the projected
image, even if the lamp normally lights.
For carrying
This unit is precision equipment. When
carrying the unit, do not subject the unit to
shocks, or fall. It may damage the unit.
When carrying the unit, firmly grab its
nonslip surfaces with both hands to avoid
