USING THE PROJECTOR

This section describes how to use and make adjustments to the projector. It also provides a reference to the keypad and remote buttons and the options available from the on-screen menus.

Basic Image Adjustment

1Make sure you have powered up your equipment in the right order (page 16).

2If the image doesn’t display completely, zoom the image (page 21), adjust the height of the projector (page 21) or center the image by adjusting its horizontal or vertical position (page 29). Be sure the projector is at a 90 degree angle to the screen.

3If the image is out of focus, rotate the focus lens (page 21).

4If the image appears to shimmer or if it has blurry vertical bars after you have adjusted the focus, turn Auto Image (page 28) off and then back on to reset the automatic sync and tracking. If that doesn’t clear up the image, turn Auto Image off and adjust the sync (page 28) and/or the tracking

(page 29) manually.

5If the colors don’t look right, adjust the brightness (page 25).

Using the Remote Control

Point the remote control at the projection screen or at the front or rear of the projector. The range for optimum operation is about 40 feet. If you point the remote at the projection screen, the dis- tance to the screen and back to the projector must be less than or equal to 40 feet. For best results, point the remote directly at the projector.

The projector ships with a remote that has four function buttons, a disk mouse and two mouse buttons, one on the top of the remote and one on the bottom.

NOTE: If you can’t aim the remote control at the projector so that its signal is received — for example, when using rear projec- tion —purchase the optional LaserPro remote and connect it directly to the projector with the optional remote control cable. See “Optional Accessories” on

page 46.
