INSTALLATION & SETUP
* For rear screen applications, less space is required if a mirror is used to fold the optical
path.
*
Choose the right screen size for your application:
- As screen size increases, magnification increases which reduces brightness. This
reduces the contrast ratio, which affects legibility. Sharp defined edges become
soft and fuzzy. Consider whether screen size is more important.
- Installing a large screen in a small room is similar to watching television close
up; too large a screen can overpower a room. A good rule of thumb is to be no
closer than 1.5 times the width of the screen.
- Larger screens require greater attention to lighting conditions.
* When laying out your projection room, consider positioning the projector and screen in
a manner, which will achieve maximum audience coverage and space efficiency. For
example, placing the screen along the larger wall in a rectangular room will reduce
audience coverage.

The projector includes a multi-use full-function keypad, which may be configured for use
as a built-in IR remote, or wired remote keypad. The keypad is configured at the factory
for built-in use. It is located below the front top cover. You can use the keypad as it is or
re-configure it for remote operation. You can also ''hard wire'' the keypad to be a protocol
A or protocol B keypad (see section 3.7,
Utility Features for information about keypad
protocols).
