Never block the projector’s suction inlets or ventilation outlets. Fail-
ure to observe this may result in the build up of high temperatures 
inside the projector, leading to the outbreak of fire. Do not place the 
projector in the following locations.
·In narrow, badly ventilated areas, such as in cupboards or in bookcases. 
·On top of carpets, matresses or blankets.
·Never cover the projectors with table cloth or other material.

vided between the projector and the wall.
Always ensure that the plug has been disconnented from the power 
socket when it is not to be used.
Failure to observe this may result in the outbreak of fire.
Always ensure that the power has been switched off, the plug has 
been disconnected from the power socket, and all other cables have 
been disconnected when moving the projector.
Failure to observe this may result in the outbreak of fire or electric shocks. 
						

							 Safety Precautions - 11
Never attempt to remove the lamp immediately after the projector has 
been used. Wait for the projector to cool down sufficiently by leaving 
it for at least sixty minutes after the power supply has been switched 
off.
Failure to observe this may result in burns or other injuries.
Misuse of the batteries may result in damage to the batteries and 
subsequent leakages, leading to the outbreak of fire, injury and prod-
uct corrosion. Observe the following precautions to ensure safety.
·Never use combinations of different batteries, or old batteries together 
with new batteries.
·Never use batteries that are not specified in the instruction manual.
·If liquid should leak from the battery, wipe up the leakage with a cloth and 
then replace the battery accordingly.
·Replace the batteries immediately when the time for replacement 
arrives.
·Remove the batteries when the projector is not to be used for a long 
period of time.
·Never apply heat to the batteries, or place them in naked flames or water.
·Ensure that the batteries are inserted in accordance with the correct 
polarity (+ and -).
·If any liquid that has leaked from a battery gets onto the hands, wash it 
off immediately with water.
Batteries must be disposed of in accordance with the regulations in effect 
in each relevant area.
Ensure that the electric plug and connectors have been discon-
nected from their sockets when performing maintenance tasks.
Failure to observe this may result in electric shocks.

Safety Precautions
Using the projector outside of the permissible temperature range (+5°C to +40°C) may 
result in unstable display and excessive loads being placed on the fan, leading to 
damage to the equipment.
Storing the projector outside of the permissible temperature range (-10°C to +60°C) 
may result in damage of the case. Take special care to avoid placing the equipment in 
direct sunlight for a long period of time.
