Using the Remote Control 
The remote control uses a line-of-sight infrared signal. To use the 
remote control, point it towards the infrared receiver located at the 
front of the projector (see page 40).
Note: To be able to use the remote control as a wireless mouse, 
make sure you have connected the mouse cable to the projector and 
your computer. (See Chapter 1 for instructions.)
You can use the remote control up to 32.8 feet (10 meters) from the 
projector. (This distance may be shorter if the remote control 
batteries are low.) You must also be within a 
± 30
° angle from the 
front receiver.

							Controlling the Projector

Note: The projector may not respond to remote control commands 
in these conditions: ambient light is too bright; a certain type of 
fluorescent light is present; a strong light source (such as direct 
sunlight) shines into the infrared receiver; or other equipment 
emitting infrared energy is present (such as a radiant room heater). 
Correct these conditions to use the remote control or control the 
projector from a computer.
