Remote Control
Operating Range
The remote control may not operate beyond certain distances and angles from 
the receiver on the projector.  Observe the following conditions during use.
[Operating Distance : Approximately 393.70inches (10m) ]
[Operating Area:]
Horizontally
Vertically
Tip:
• The remote control R/C switch must be switched to On to use the remote control.
 Point the remote control towards the remote control receiver on the projector unit.
 Certain screens may shorten the operating distance (approximately 393.70inches 
(10m) ) of the remote control when the control is pointed towards the screen to reflect 
its signal during use.
 Situate the remote control receiver out of direct sunlight, fluorescent light, and 
similar light sources.
These may cause the remote control to malfunction.
 If the remote control malfunctions or stops operating, the batteries may need 
changing.
Replace the batteries with a fresh set.

Special Notes on Setup
The best picture is obtained when the projector and screen are set up facing 
each other directly, as shown below. Set your projector and screen up this way.
[View from right or left]
Keystone correction allows correction of trapezoidal distortion (See pages 29, 
47).
[View from above or below]
Caution:
 Do not block the air exhaust vent on the side of the projector or the air inlets on the 
right side and rear of the projector.
 Do not place the unit in direct contact with air conditioner, heater, or other 
ventilation currents.
 When setting up the projector near walls, allow at least 7.87inches (20cm) from all

Connecting to a Computer
Computers which can be connected
Some computer models may not allow connection, and others may allow 
connection but not projection.
Make sure that the specifications of the computer you are using for connection 
meet the following two requirements.
[The computer must have a video signal output port]
Make sure that the computer has a port that outputs a video signal.
A port that outputs a video signal is called an RGB port, monitor port, or 
video port or the like.
Consult the section describing connection to an external monitor or the like 
in the instruction manual for the computer that you are using, and make sure 
that the computer has a video signal output port.
Computers with an integrated monitor and other components as well as 
laptop computers may require separate purchase of an external output port.
In other cases, an external output port cannot be attached.
[The resolution and frequency of the computer must be within the range of 
specifications shown on the following page]
The resolution and frequency of the video signal output by your computer 
must be compatible with your projector in order to allow projection (some 
computers allow partial projection, but clear projection cannot be obtained).
Check the resolution and frequency of the video signal in the instruction 
manual of the computer you are using for projection.
