• Do not place any objects, which are easily affected by heat, in front of the projection window. Doing so could
lead to the object melting from the heat that is emitted from the light output.
Place the projector in a horizontal position
The tilt angle of the projector should not exceed 10 degrees, nor should the projector be installed in any way other
than the desktop and ceiling mount, otherwise lamp life could decrease dramatically.

Fire and Shock Precautions
• Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your
projector. Allow at least 4 inches (10cm) of space between your projector and a wall.
• Do not try to touch the exhaust vent as it can become heated while the projector is turned on and immediately after
the projector is turned off. Parts of the projector may become temporarily heated if the projector is turned off with
the POWER button or if the AC power supply is disconnected during normal projector operation.
Use caution when picking up the projector.
• Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to retrieve
any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your
projector. If something should fall into your projector, disconnect it immediately and have the object removed by a
qualified service personnel.
• Do not place any objects on top of the projector.
• Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
• The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply
fits this requirement before attempting to use your projector.
• Do not look into the projection window while the projector is on. Serious damage to your eyes could result.
• Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the
projection window is extensive, therefore any kind of abnormal objects that can redirect light coming out of the
projection window, can cause unpredictable outcome such as fire or injury to the eyes.
• Do not place any objects, which are easily affected by heat, in front of a projector exhaust vent.
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the ex-
haust.
• Do not splash water over the projector. Doing so can cause electrical shock or fire. If the projector gets wet, turn off
the projector, unplug the power cord and have the projector serviced by a qualified service personnel.
• Handle the power cord carefully. A damaged or frayed power cord can cause electric shock or fire.
- Do not use any power cord other than the one supplied with the projector.
