Warning, Notices and Safety Instructions
Do not tilt the projector more than 10 degrees.
The maximum tilt angle for the projector is 10 degrees.
When the projector is tilted more than 10 degrees, it will shorten the life of the projector lamp and
may lead to other unpredictable damages.
Can’t >10°
Can’t >10°
Congurations for projector operation at high altitudes
When operating the projector at higher altitudes, be sure to manually set the fan mode to "High" or
it could shorten the life of the optical system in the projector. High altitude is dened as places being
1500 meters (4900 feet) or higher.
Please refer to " Page 43 : High Altitude Mode ".
Keep the projector's ventilation inlets and outlets free from obstructions
Be sure to keep objects for no less than 30cm away from the ventilation inlets and outlets of the
projector and note the direction of air ow at the designated spot of installation. Do not let the hot air
released from the outlet ow back to the inlet as it will prevent proper cooling and lead to 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 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). Please refer to " Page 58 : LED STATUS ".
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.
Protect the projector with care
When placing the projector at a high position, be sure to secure the projector rmly so that it would
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.
