Using the remote control The remote uses two (2) provided AAA batteries (Hitachi Maxell, part num-
ber LR03). They are easily installed by sliding the cover off the remotes 
back, aligning the + and - ends of the batteries, sliding them into place, and 
then replacing the cover.
To operate, point the remote at the projection screen or at the projector (not 
at the computer). The range of optimum operation is about 16 feet (5m).For 
best results, aim the remote directly at the projector.
To use the laser pointer, press and hold the Laser button. The laser turns off 
when the button is released, or times out after two (2) minutes of continu-
ous operation.
WA R N I N G: Do not look into the laser beam emitted from the top of the 
remote control.
The remote contains four Source buttons that allow you to assign a particu-
lar input to a specific source. Simply press the numbered Source buttons to 
travel to whatever four sources you wish to have available. 
Press the remotes Menu button to open the projectors menu system. Use 
the arrow buttons to navigate, and the Select button to select features and 
adjust values in the menus. 
The remote also has a power button to turn the projector on and off, volume 
buttons and a mute button to control the sound, a backlight button to light 
the remotes buttons in the dark, and a video and computer button to switch 
between those two sources.
Two presentation-specific features are also provided. Use the blank button 
to display a blank screen instead of the current slide; use the effect button to 
invoke a user-definable action, such as freeze, PiP, or magnify.
The Auto Image button reacquires the computer image and the Presets but-
ton lets you customize the settings for each source. Up to three Preset set-
tings can be customized and saved.
Troubleshooting the remote Make sure the batteries are installed in the proper orientation and are 
not dead. The LED at the top of the remote lights when any button is 
pressed when the battery power is adequate.
 Make sure you’re pointing the remote at the projector, not the com-
puter, and are within the remote range of 16 feet (5m).

responds to Computer 3, Audio 3 corresponds to Video 2 and 3, and 
Audio 4 corresponds to Video 1. You can change these assignments, 
see page 31.
