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 11).
2If the image doesn’t display completely, rotate the zoom ring 
(below), adjust the height of the projector (page 16) or center 
the image by adjusting its horizontal or vertical position 
(page 23). Be sure the projector lens is at a 90 degree angle to 
the screen.
3If the image is out of focus, rotate the focus ring (below).
4If the colors don’t look right, adjust the brightness, contrast, 
tint, or color (page 21).
Adjusting the Projector
To focus the image, rotate the focus ring (Figure 10) until the 
image is clear. To zoom the image, rotate the zoom ring. This 
adjusts the image size.
NOTE: To obtain the best overall 
focus quality, open the menu and 
focus on the text. This will ensure 
that the best overall image quality 
is achieved.

Using the Remote Control
To advance PowerPoint slides with the projector ’s remote, you 
must connect the USB cable on the projector ’s computer cable to 
the computer. See page 8 for more information.
Point the remote control at the projection screen or at the front or 
rear of the projector (not at the computer). The range for opti-
mum operation is about 30 feet. If you point the remote at the 
projection screen, the distance to the screen and back to the pro-
jector must be less than or equal to 30 feet. For best results, point 
the remote directly at the projector.
