Projector Installation — Introduction
Physical and electrical installation of the TransVision™ 4 must be performed 
only by a trained professional who is knowledgeable about both the specifics 
of the TransVision
™ 4 and the requirements of the local building and electrical 
codes.
Physical installation of the TransVision
™ 4 may be divided into 3 steps:
(1)  Pre-installation planning, which includes plotting the projector-to-screen  distance. This requires knowledge of the screen size and placement....

 Projectors  with  fixed-pixel  imaging  arrays,  such  as  DLP  or  LCD,  are  not 
recommended  for  use  with  perforated  screens.  Perforated  screens  have 
highly regular microscopic patterns that conflict with the equally uniform 
pattern in the digital image array. This creates interference, a visual artifact 
called a “moiré” pattern, which compromises picture quality. 
 To eliminate light spill, a black felt border is also recommended to enhance 
the viewing experience.

B. Mounting and Throw Distance Calculation
Before starting the installation you will need to calculate the projector throw 
distance and the ceiling to top-of-picture offset. The throw distance and the 
precise center of the screen are then used to determine the exact location for 
the physical installation of the projector. The TransVision
™’s zoom lens allows for a wide range of throw distance op-
tions — the distance from the projector to the screen. For maximum flexibility 
in adjustment we...

For floor-mounted installations the picture offset is the distance between 
the mounting surface of the projector and the bottom of the picture. In order 
to deliver pictures that are free of keystone distortion, be certain to calculate 
the offset distance before ordering screens and/or cabinetry. Although some 
adjustment range is available in floor mounted systems by using the adjust
-
able feet.

2B. Ceiling Mount Preparation
Once  the  throw  distance  has  been  calculated  and  the  screen  installed,  the 
next step in the installation is to locate the precise mounting position of the 
projector.  The ceiling mount bracket must be aligned to the middle of the screen and 
located  as  close  as  possible  to  an  electrical  source  AND  a  support  beam.  If 
the projector is not located properly,  it is not possible to compensate for any 
resulting “keystone” distortion in the projected...

 2C. Ceiling Mount Installation and Projector Mounting
The optional ceiling mount kit (CMB) consists of three parts. Before beginning 
the installation process, first identify each of the three parts of the mounting 
system as shown in the pictures below.
NOTE:  The  ceiling  must  be  capable  of  safely  supporting  the  weight  of  the 
projector and mount, which is approximately 25 pounds.
