Folded Optics
In rear-screen applications where space behind the projector is limited,\
 a mirror may be used to fold the optical path, 
as shown in Figure 3-4. The position of the projector and mirror must be\
 accurately set. If you are considering this type 
of installation, contact your dealer for assistance.

Lens Shift
The H9080FD has a lens shift capability which allows the vertical moveme\
nt of the image without moving the projector.
Lens shift is generally expressed as a percentage of the screen height. \
For ceiling mounted projectors, the lens can be 
moved 120% (0.6V) downward, while the lens can be moved 120% (0.6V) \
up or down on a desktop mounted projector.

3.3 Mounting the H9080FD
There are several methods for mounting the projector. Depending on your \
chosen installation, one method may be 
more suitable than another.
Floor Mounting (Upright)
In typical front and rear screen installations, the projector can be mou\
nted to a secure and level surface such as a 
table or cart. Carts are useful when moving a projector during a present\
ation or from site to site. If possible, lock the 
wheels when it’s in position to prevent it from being moved...

Connecting an External IR Receiver
If infrared signals from the remote control cannot reach the projector d\
ue to excessive distance or obstructions such as 
walls or cabinet doors, you can connect an external IR repeater system t\
o the IR INPUT on the H9080FD to extend the 
range of the remote control. See Figure 3-12.
