Precautions with regard to safety (continued)
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 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. Please put the standard lens cover on
the projector when you do not use it.
DO NOT MOVE THE PROJECTOR WHILE
IT IS OPERATING OR SUBJECT IT TO
VIBRATION OR IMPACT.
The service life of its internal components will be
shortened.
THE PROJECTOR HAS A HIGH
PRESSURE MERCURY LAMP THAT IS
CHARACTERIZED AS FOLLOWS:
The brightness of the lamp will decrease over time.
•
The lamp may explode or shorten the lamp life by
•
shocks or chipping damage.
In rare cases, it may burst shortly after the first use.
•
The possibility of its bursting increases when the lamp
•
is used beyond the replacement time.
If the lamp bursts, gas inside the lamp is released in
•
the form of smoke.
The life of a mercury lamp varies according to the
•
individual difference or conditions of use.
In particular, turning the power on and off frequently
•
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 power cord supplied with the
corresponding device and a commercially available
shielded interface cable.
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
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 liquid
crystal panel. Display the white screen test pattern for
more than an hour to remove it. See “TEST PATTERN”
