Notices you should read prior to the installation of the projector

Installation environment for the projector
Do not install the projector at place with excessive dampness, dust or smoke. If installation in such
environment is unavoidable, be sure to clean the interior of the projector routinely to prolong the
dispatched by your local dealer so do not clean the inside of the projector by yourself.
If other light source is directly projected onto the projector screen, the color of the picture from the
projector will appear to be pale and the picture quality will be lower. In addition, your eyes would be
more prone to fatigue. Therefore, it is recommended that the projector be installed in places without
direct exposure to sunlight or other strong light source.
The ideal operating temperature range : 0°C ~ 45°C (32°F ~ 113°F)
The ideal storage temperature range : -10°C~ 60°C (14°F ~ 140°F)
When operating the projector at higher altitudes, be sure to set the fan mode manually to "HIGH-1",
"HIGH-2", or "HIGH-3". Otherwise, it could shorten the life of the optical system in the projector.
For details, see User's Manual - Operating Guide.
Protect the projector with care
not fall and cause injuries. Take care to protect the projector's lens from collision, abrasion or other
damages. Be sure to close the lens cover or cover the projector with a dust cover if you need to store
the projector or if it will not be used for a long time.
Keep obstacles away from the projector's ventilation inlets and outlets
damage of the projector's internal structure.
In the event of high temperature due to malfunctioning of the internal cooling fan caused by clogging at the
ventilation inlets and outlets, the projector will activate its automatic protection mode and shutdown. When
this happens, it does not necessarily mean that the equipment is malfunctioning. Unplug the power cord
from the outlet and wait approximately 15 minutes before operating the projector again (remember to remove
the objects that have caused poor ventilation so that the projector will not go into the protection mode again).
Description: Temperature inside the projector is automatically adjusted by cooling fans. Therefore, it does
not mean that a problem has occurred in the projector even if you hear the sound of cooling fan and its
operating speed change.
