Warning
•
You m
ust install a ceiling mount when suspending the projector from a ceiling. If
you do not install the projector correctly, it could fall and cause damage or injury.
•
Do not use adhesives on the mounting hole to prevent the screws from loosening,
or use lubricants, oils, or similar substances on the projector; the projector case
may crack causing it to fall. is could cause serious injury to anyone under the
ceiling mount and could damage the projector.
•
Do not install the projector in a location subject to high levels of dust or humidity,
or in a location subject to smoke or steam. Otherwise, it could cause a re
or electric shock to occur. e projector's case could also deteriorate and be
damaged causing the projector to fall from the mount.
Examples of environments that could cause the projector to fall due to case
deterioration
•
Locations subject to excessive smoke or airborne oil particles, such as factories
or kitchens
•
Locations containing volatile solvents or chemicals, such as factories or
laboratories
•
Locations where the projector could be subjected to detergents or chemicals,
such as factories or kitchens
•
Locations in which aroma oils are oen used, such as relaxation rooms
•
Near devices that produce excessive smoke, airborne oil particles, or foam at
events
•
Locations near humidiers
Warning
•
Do no
t cover the projector's air intake or air exhaust vents. If the vents are
covered, the internal temperature could rise and cause a re.
•
Do not use or store the projector in locations where it will be subject to dust or
dirt. Otherwise, the quality of the projected image may decline, or the air lter
may become clogged, resulting in a malfunction or re.
•
Do not install the projector on an unstable surface or in a location beyond the
weight specications of the projector. Otherwise, it could fall or topple causing an
accident and injury.
•
When installing the projector in a high position, take measures to prevent falling
by using wires to ensure safety in an emergency, such as an earthquake, and to
prevent accidents. If it is not installed correctly, it could fall causing an accident
and injury.
•
Do not install in locations where salt damage could occur, or in locations subject
to corrosive gas such as sulphuric gas from hot springs. Otherwise, corrosion
could cause the projector to fall. It could also cause the projector to malfunction.

Correcting the Image Shape and Focus Automatically
e projector automatically corrects the focus and any keystone distortion of
the projected image in the following situations:
•
When you turn on the projector.
•
When the projector is moved or tilted.
Focus and keystone distortion can be automatically corrected under the
following conditions:
•
When the size of the projected image (diagonal length) before correcting the
focus and keystone distortion is from 30 to 100 inches.
•
When the projection distance is about 0.7 to 2.2 m.
•
When the installation angle of the projector toward the projection surface is
within 20º right, le, up, or down.
•
Foc
us and keystone distortion are corrected even if the size of the
projected image exceeds 100 inches. However, the adjustment may fail
depending on the installation angle of the projector, the brightness of
the room, and the material of the projection surface. If necessary, adjust
the keystone distortion and focus settings manually using the projector
menu.
•
When an image is being projected at an angle and has been reduced
using the Zoom function, keystone distortion may not be corrected. If
the correction fails, adjust the reduction ratio of the image so that it is
closer to 100%.
