Here are some other considerations and tips that can help you improve your
installation:
•
Ventilation is an important factor when preparing a projection room. The ambient
temperature should be kept constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature can
cause drifts in the projector circuitry, which may affect performance.
•
Keep the projector away from devices, which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide projectors,
speakers, power amplifiers, elevators, etc.
•
Use an optical mirror for rear screen installations to shorten the optical light path
and use less space in the projection room.
•
Choose the right screen size for the application:
◊
As screen size increases, magnification increases, which reduces
brightness. Select a screen size, which is appropriate for the venue, but
not larger than that required.
◊
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 designing a projection room consider positioning the projector and screen
where maximum audience coverage and space efficiency is achieved. For
example, placing the screen along the larger wall in a rectangular room reduces
audience coverage.
Step 1 - Unpack the Projector
The projector leaves the factory fully assembled and carefully packaged for
transportation. When you receive your projector it is important you remove and
discard the packaging material surrounding the modules and air vents. Check the
cable connections between modules to ensure they have not become loose during
shipping. In the event you have to reconnect a projector cable, refer to Appendix A.
Step 2 - Modify Projector Configuration
The projector configuration can be modified from 0 degrees - lens horizontal (the
way its shipped from the factory) to 90 degrees - lens vertical. Use the following
instructions to change the projector's configuration.
1. With the projector off and unplugged, disconnect all harness connections
between the PHM and EM. It is easiest to remove the small panel where the
zipper tube enters the EM (remove 1 clamp, 4 screws). With this panel removed
you can access the connections made to the Control PCB. Disconnect all
harnesses between the PHM and EM.
2. Remove the four wing nuts securing the PHM assembly to the adjuster. See
Figure 1.
