Connect the Line Cord 
 The North American-rated line cord is provided with each projector. Ensure 
that you are using a line cord, socket and power plug that meets the 
appropriate local rating standards.
 
Plug the line cord to the AC receptacle located on the right hand side of the projector 
and the three-pronged end into a grounded AC outlet. Ensure the socket outlet is 
installed near the equipment and is easily...

Rear screen installations 
There are two basic types of rear screens: diffused and optical.  
A diffused screen has a surface, which spreads the light striking it. Purely diffused 
screens have a gain of less than one. The main advantage of the diffused screen is its 
wide viewing angle, similar to that of a flat screen for front screen projection. This 
type of screen is suitable when a wide viewing angle is required but...

To fill a screen with an image, the aspect ratio of the screen should be equal to the 
aspect ratio of the image (expressed as the ratio of its width to its height). Standard 
video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR 
output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the screen 
must be at least 13.3feet (4m). 
The high brightness of this projector is well suited for...

Vertical and horizontal position  
The correct vertical and horizontal position of the projector in relation to the screen 
depends on the lens type and the screen size. Ideally, the projector should be 
positioned perpendicular to the screen. This way, the image will appear rectangular 
instead of keystoned (trapezoidal).  
The vertical position of the image can be offset – that is moved above or below the 
optical axis...

The horizontal position of the image can be offset – that is moved to the left or right 
of lens center, by adjusting the fully motorized lens mount through software. The 
amount of horizontal offset available depends on the lens installed and if the image 
has already been vertically offset. Horizontal offset can also be expressed as the 
percent of half the image width – the number of pixels of shift to one side of lens 
center....

Mounting  
There are several methods for mounting the projector. Depending on your chosen 
installation, one method may be more suitable than another. In typical front and rear 
screen installations the projector can be mounted to a secure and level surface, such as 
a table or cart. Carts are useful when the projector has to be moved during a 
presentation or from site to site. It is recommended you lock the wheels on a cart,...
