Note: These sizes are +10 percent. This is due to variations in the manufacture of the lens. If you are close to one of the endpoints you should verify with your unit that the image is the proper size at the proper 
distance. * USB secure memory devices and USB hubs are not supported.

Quick Start and Instant Off:

 The image will appear 

in just 3 seconds after Power On and the unit can 
be instantly powered off after a presentation.

Input source naming:

 Change the name of any input 

to one of your own choosing for easier use (i.e. change 
“RGB Input” to “Computer” or “Component” to “DVD”.)

Auto Vertical Keystone: 

Automatically 

performs keystone correction for an ideal screen 
setting, simply by pressing the button.

Resolutions preset:

 Recognizes and resizes 

special resolutions, such as WXGA, and places them 
in the optimum position. User’s own resolutions 
can also be stored as custom modes.

“My Screen” lock:

 Users can personalize the start-

up screen with a warning or ownership message 
and lock this screen with a pin code number.

Anti-theft security bar:

 Serving as both a 

visible and actual deterrent, a steel security 
bar is connected to the chassis to help provide 
a strong anchor point for a lock chain.

Whiteboard, Blackboard and Daytime Modes:

 

Whiteboard Mode helps reduce peak white 
brightness of projection on a whiteboard, reducing 
annoying glare. Blackboard Mode helps provide 
better color balance when projecting onto a colored 
background. Daytime Mode allows the viewer to see 
vivid images, even in high-glare environments.

Transition detector:

 Locks the projector from 

use if the projection angle or settings are 
changed from the installed position. Requires 
a user-set numeric code for reactivation.
