Usage Guidelines
•
Do not look directly into the projection lens when the projector 
is turned on. The bright light may harm your eyes.
•
The top and bottom of the projector can be very hot to the 
touch after use. Use extreme care or let it cool before lifting it.
•
Do not block the grills at the front, side, top or bottom of the 
projector. Restricting the air flow through the projector can 
cause it to overheat and turn off.
NOTE: If the projector overheats
and turns off, you must wait 45
seconds before you attempt to
turn it back on.
•
Handle the projector as you would any product with glass 
components. Be especially careful not to drop it.
•
Avoid leaving the projector in direct sunlight or extreme cold 
for extended periods of time. If this happens, allow it to reach 
room temperature before use.
•
Transport the projector in a vendor-approved hard or soft case. 
Call your In Focus dealer for more information.
