This projector is made of precision components. Failure to observe the following precautions can
result in inability to correctly save data and malfunction.
●
Never use or store the projector in the following locations. Doing so creates the
risk of malfunction of and damage to the projector.
z
Locations subjected to electrostatic charge
z
Locations subjected to temperature extremes
z
Locations where there is extreme moisture
z
Locations subjected to sudden temperature changes
z
Locations where there is a lot of dust
z
On a shaky, slanted, or otherwise unstable surface
z
Locations where there is the danger of getting wet
●
Avoid using the projector under the following conditions. Such conditions create
the risk of malfunction of and damage to the projector.
z
Avoid areas subject to temperature extremes (operating
temperature range is 5°C to 35°C (41°F to 95°F)).
z
Never place heavy objects on the projector or climb on
top of the projector.
z
Never insert or allow foreign objects to drop into the
projector.
z
Never place a vase or any other container of water on
top of the projector.
●
Never leave a dead battery inside the remote controller for a long time.
A dead battery can leak, which leads to malfunction of and damage to the remote controller.
●
Clean with a soft, dry cloth.
When very dirty, use a soft cloth that has been dampened in a weak solution of water and a
mild neutral detergent. Wring all excess water from the cloth before wiping. Never use thinner,
benzene, or any other volatile agent to clean the projector. Doing so can remove its markings
and cause staining of the case.
●
Missing Screen Dots
Though this projector is manufactured using the most advanced digital technology available today,
some of the dots on the screen may be missing. This is normal, and does not indicate
malfunction.
●
Never subject the projector to strong impact while it is projecting.
If the projector is accidentally subjected to strong impact, the projection image will momentarily
go blank. The image will reappear after some time, but it may be the wrong color or it may be
accompanied by an error message.
If the projected image is the wrong color, re-select the current input source. If this does not
return the projected image to its proper color, use the procedure under “To turn off the
projector” on page E-21 to turn projector power off and then back on again.
If the image reappears with an error message, correct the problem in accordance with the
indicator explanations in the “Troubleshooting” guide on page E-30.
●
Keystone Correction and Image Quality
Performing keystone correction causes the image to be compressed before it is projected. This
can result distortion of the image or a loss of image quality. If this happens, change orientation
of the projector and/or screen so it conforms as much as possible to the illustration under
“Setting Up the Projector” on page E-14.
If image quality is the highest priority, turn off auto keystone correction and position the
projector so it is pointed straight at the screen.
