LitePro 560/570 User’s Guide 49
Problem: Image is not centered on the screen
Use the arrow buttons on the remote to center the image. (The
menu must be off when you re-position the image. When the
menu is displayed, the arrow buttons have a different function.)
Refer to “arrow buttons” on page 21 for more information.
Problem: Only the test pattern is displayed
Are your cables connected correctly? Check to see that the cable
is connected to the graphics port on the computer (this is the
connector where your monitor cable usually goes).
Did you turn on the equipment in the correct order? You may
need to repeat the power up sequence. The equipment must be
powered on in this order: LitePro, computer monitor, computer.
It is especially important that this sequence be followed for
Macintosh computers.
Is your computer graphics system set up correctly? Is your
computer’s graphics board turned on?
Problem: Image is too wide or narrow for screen
You may need to adjust the tracking to reduce or enlarge the
projected image. Refer to “Tracking” on page 33 for more
information.
You may need to adjust the resolution of your monitor if it is
greater than 800x600 pixels. Otherwise, your presentation display
may appear overly compressed.
Problem: Image is out of focus
Turn the projection lens to focus the image.
The projection screen must be at least 4 feet (1.2m) from the
LitePro.
The projection lens may need cleaning.
Problem: Remote not operating correctly
You may need to replace the batteries in the remote. Refer to
“Replacing Batteries in the Remote Control” on page 42 for
instructions.
