Warning, Notices and Safety Instructions
Notices you should read prior to the installation of the projector
Take frequent breaks to let your eyes rest
Prolonged viewing of the projector screen could strain your eyes. Please be sure to rest your eyes
adequately.
Installation environment for the projector
You should avoid installing the projector at place of excessive dampness, dust or smoke. If installation
in such environment is unavoidable, be sure to have the interior of the projector
cleaned routinely to prolong the projector's lifecycle. Cleaning of the projector's interior should only be
to 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 sources of intense light.
The ideal operating temperature range for the projector is between 0°C ~ 40°C (32°F ~ 104°F)
The ideal storage temperature range for the projector is between -10°C~ 60°C (14°F ~ 140°F)
When operating the projector at higher altitudes, be sure to manually set the fan mode to "High" or
1219 meters (4000 feet) or higher.
Please refer to " Page 49 : High Altitude "
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 an extended time.
Keep the projector's ventilation inlets and outlets free from obstructions
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 necessary mean that the equipment is malfunctioning. Try to unplug the power cord
from the wall outlet and wait for 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: The regulation of temperature inside the projector by the cooling fan is automatic. And as such,
the sound of cooling fan changing its operating speed does not imply that a problem has occurred with the
projector.
