After completing the focus alignment, you should use the image adjustment program to
obtain the best display quality. This program specify the electrical parameters in order to
obtain best display quality.
5.1.2 Running the Program
The image adjustment program is supplied on an MS-DOS diskette. Follow the
messages in the image adjustment program as you select menu options.
When menu options 1 through 4 are executed, the image adjustment program transfers
the adjusted settings to the projector’s RAM via the RS-232C interface. Unless you save
these settings, they are lost and invalid when the projector is restarted. Therefore, once
you make adjustments in the image adjustment program, choose menu option 5, "Data
Transfer," to program settings into the projector’s flash ROM.
* Do not use menu option 6 (standard data transfer) unless specifically told to do so.
1. Place the screen about 8 feet (2.4 m) away from the projector.
2. Turn on the projector and host computer.

focus. Use the zoom ring to set the screen projection size to 60 inches.
