Cautions on use
In order to get the picture quality
Draw curtains or blinds over windows and turn off any
lights near the screen to prevent outside light or light
from indoor lamps from shining onto the screen.
Depending on where the projector is used, air exhaust
vents or the warm air from air conditioning can cause
a shimmering effect on the screen. For this reason,
take care not to shield the air exhaust vents and con-

Do not touch the surface of the
projector lens cover with your
bare hand.

Do not move the projector while it
is operating or subject it to vibra-
tion or impact.
The service life of its internal components will be
shortened.
The projector has a high pressure
mercury lamp that is characterised
as follows:
The brightness of the lamp will decrease over time.
z
The lamp may explode or shorten the lamp life by
z
shocks or chipping damage.
Inrarecases,itmayburstshortlyaftertherstuse.
z
The possibility of its bursting increases when the
z
lamp is used beyond the replacement time.
If the lamp bursts, gas inside the lamp is released
z
in the form of smoke.
The life of a mercury lamp varies according to the
z
individual difference or conditions of use.
In particular, turning the power on and off frequently
z
and/or repeatedly as well as continuous use for
10 hours will greatly affect the life cycle. Provide a
lamp for replacement in advance.
Connection to external device
When connecting the projector to a computer or
external device, use the mains lead supplied with the
corresponding device and a commercially available
shielded interface cable.
Optical components
It may be necessary to replace the optical compo-
nents such as Liquid crystal panels and Polarizing
plates in less than 1 year if using the projector in a
high temperature environment or in a very dusty, oily
smoke or tobacco smoke environment. For more
details, please contact your dealer.
Liquid crystal panel
The Liquid crystal panels are precision-made. Note
that in rare cases, pixels of high precision could be
missing or always lit, but this is not a malfunction.
Do not project the same image for long periods of
time, as this may remain as an afterimage on the liq-
uid crystal panel. Display the white screen test pattern
for more than an hour to remove it. See “TEST PAT-
TERN” on page 44.
