Precautions Concerning the Installation!
$Floor
Install the projector on a horizontal, stable surface. Do not install it on a wall or
a ceiling or a weak and rickety place that is subjected to vibration. Be sure to
install it on a firm, stable surface. Failure to heed this precaution may result in
the unit toppling over and fall down.
$Fixing Projector
Be sure and fix Projector with a bolt, etc. Failure to heed this warning may result
in a slip down for itself if earthquake.
$Water
%Install the projector in a place where it is not exposed to rain, and so on.
%When cleaning the floor, ensure that water does not get onto the projector.
%In regions that are subject to flooding, study in advance a method of moving the
display to safety.
$High frequency waves
Note that if a high frequency device is used in the vicinity, the high frequency waves
emitted by it may cause the projector to malfunction. Note also that the projector itself
emits high frequency waves, although they are weak. This can conceivably cause
interference to a television set that uses an indoor antenna, a radio receiver or a
transceiver. For this reason, keep the unit at least 30 m away from such appliances.
$Ambient light
%Although you can use this projector even in a brightly illuminated room, do not install
it in a place where light strikes the screen directly.
(Recommended conditions of use: Incident illumination of screen: 100 lx max)
%Install the projector in a location where there is no light source brighter than the light
emitted from the projector, including any light source at the rear of the projector,
within the visual field of the projector. Failure to heed this precaution will result in
eyestrain.
