Using the On-Screen Menus
The projector
 has six drop-down menus that allow you to make 
image adjustments and change a variety of settings. Most of these 
adjustments aren’t available directly from the keypad. 
NOTE: Some menu items may be 
grayed out at certain times. This 
indicates the item is not applicable 
to your setup (for example, video 
standards do not apply to com-
puter sources) or the item is not 
enabled until another selection is 
made (for example, Manual Track-
ing is not available until Auto 
Image is turned off).
To open the on-screen menus, press the menu button on the 
keypad. This changes the volume, source, and standby buttons 
on the keypad to menu navigation buttons (and illuminates the 
keypad green). Press the corresponding buttons to move the 
cursor up, down, left, or right. To select a menu, move the cursor 
left and right to highlight the menu you want. The drop-down 
menu appears. 
FIGURE 12
Drop-down menu
To change a menu setting, use the up and down arrow keys on 
the keypad to move the cursor up and down to the item you want 
to change (the selected item is highlighted red), then use the left 
and right mouse buttons (not the left and right arrow buttons) to 
adjust a setting. Some submenus, such as Brightness, consist of a 
slider bar you use to increase or decrease a value; some sub-
menus, such as Standby Time, consist of options you scroll 
through to select the desired one. All changes are saved when 
you close the menus.
To access another menu, use the left and right arrow buttons to 
move left or right to another menu.

Auto Image
NOTE: Some screen savers inter-
fere with the operation of Auto 
Image. If you’re experiencing prob-
lems, try turning your screen saver 
off, then turning Auto Image off 
and back on.
The projector automatically adjusts tracking, signal synchroniza-
tion and vertical and horizontal position for most computers 
(Auto Image does not apply to video sources). If you want to 
adjust these features manually, you must turn off 
Auto Image first 
by highlighting Auto Image in the Image menu and clicking 
either mouse button to select “off”.
Auto Resize
Auto Resize
 automatically resizes the image by scaling it up or 
down. It only affects computer images that are not in the projec-
tor ’s native resolution of 800x600.
When 
Auto Resize is on, the projector makes the best fit of the 
image to the screen. If you turn 
Auto Resize off (by highlighting it 
in the Image menu and clicking either mouse button to select 
“off”), the image may be either cropped or too small for the 
screen.
Manual Sync
The projector adjusts signal synchronization automatically for 
most computers. But if the projected computer image looks noisy 
or streaked, try turning 
Auto Image off then back on again. If the 
image still looks bad, try adjusting the signal synchronization 
manually:
1Turn Auto Image off.
2Highlight Manual sync, then press either mouse button 
repeatedly until the image is sharp and free of streaks.

Manual Tracking
The projector adjusts tracking automatically to match the video 
signal from your computer. However, if the display shows evenly 
spaced, fuzzy, vertical lines or if the projected image is too wide 
or too narrow for the screen, try turning 
Auto Image off then back 
on again. If the image is still bad, try adjusting the tracking man-
ually:

jector.

Follow these steps to manually adjust the horizontal position:
1Turn Auto Image off.
2Highlight Horizontal position, then press the left mouse but-
ton to move the image right or press the right mouse button to 
move the image left.
Positioning adjustments are saved when you power off the pro-
jector.

Video Standard
NOTE: If you already know the 
video standard used in your geo-
graphical area, it’s often best to 
manually select it.
When Video standard is set to Auto, the projector attempts to 
pick the video standard (NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, 
or SECAM) automatically based on the input signal it receives. 
(The video standard options may vary depending on your region 
of the world.) The input signals for SECAM, PAL-M, and PAL-N 
video cannot be automatically detected, therefore they must be 
chosen manually. If the projector is unable to detect the correct 
standard, the colors might not look right or the image might 
appear “torn.” If this happens, manually select a standard by 
clicking either mouse button and cycling through the standards.
Standby Time
This option lets you select how long the lamp stays on and the 
blank screen is displayed when the projector enters standby 
mode before the projector turns off. Select among 1, 5, 10, and 15 
minutes and 1 and 2 hours by clicking either mouse button and 
cycling through the options.
Ceiling Projection
NOTE: To order the Ceiling 
Mount, refer to “Optional Accesso-
ries” on page 40.
When you turn Ceiling Projection on, the projector turns the 
image upside down for ceiling-mounted projection. Highlight 
Ceiling Projection, then click either mouse button to turn this fea-
ture on and off.
