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 consider
the direction of the air flowing from air conditioning.
Do not adjust the lens focus in the initial period
z
(within approx. 30 minutes) after switching the
projector on.
Do not touch the surface of the
projector lens with your bare hand.
If the surface of the lens becomes dirty from fingerprints
or anything else, this will be magnified and projected
onto the screen. Cover the lens with the lens cap when
the projector is not used.
The projector has a high pressure
mercury lamp that is characterized
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.
In rare cases, it may burst shortly after the first use.
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
12 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 power cord supplied with the
corresponding device and a commercially available
shielded interface cable.
Precautions with regard to safety
Optical components
It may be necessary to replace the optical components
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
Do not project the same image for long periods of
time, as this may remain as an afterimage on the liquid
crystal panel. Display the white screen test pattern
for more than an hour to remove it. See the functional
instructions that is in the provided CD-ROM.
Cleaning and maintenance
Ask an Authorized Service Center
to clean the inside of the projector
at least once a year.
If dust is left to build up inside the projector without
being cleaned out, it can result in fire or problems
with operation. It is a good idea to clean the inside of
the projector before the season when humid weather
arrives.
Ask your nearest Authorized Service Center to clean
the projector when required.
Please discuss with the Authorized Service Center
regarding cleaning costs.
Be sure to remove the power plug from the wall
z
outlet before cleaning.
Use soft and dry cloth to clean the cabinet.
z
Use a soft cloth moistened in warm water to clean
away oil. Do not use solvents such as benzene,
thinner, and alcohol, detergents for kitchens, or a
chemical cloth. If using such solvents, the outer case
will become deformed, and the paint may peel off.
Do not clean the lens surface with fuzzy or
z
dusty cloths.
If dust adheres to the lens, it will be magnified and
projected on the screen. Use a soft and clean cloth
to wipe off dust.
