Using the remote controlThe remote uses two (2) provided AA batteries. They are easily installed by 
sliding the cover off the remote’s back, aligning the + and - ends of the bat-
teries, sliding them into place, and then replacing the cover.
Caution: When replacing the batteries, be aware that using batteries other 
than the type provided with the projector may risk severe damage to the 
remote. When disposing of the batteries, be sure to do so in an environmen-
tally proper manner.
To operate, point the remote at the projection screen or at the projector (not 
at the computer). The range of optimum operation is about 15 feet (4.5m).
Pressing the remote’s Pow e r button when the projector ’s Power toggle 
switch is in the Off position does not cause the projector to power up. You 
need to put the projector ’s Power toggle switch in the On position to let the 
remote power on the projector.
When the projector is running, you can press the remote’s Pow e r button to 
place the projector in the Off state (see page 22 for shutdown info) and 
power it off.
Press the remote’s Menu button to open the projector ’s menu system. Use 
the arrow buttons to navigate, and the Select button to select features and 
adjust values in the menus. See page 35 for more info on the menus.
The remote also has Vo l u m e and Mute buttons to control the sound, and 
Video and Computer buttons to switch between sources.
Two presentation-specific features are also provided. Use the Blank button 
to display a blank screen instead of the current slide (you can choose which 
color is displayed, see page 40); use the Effect button to invoke a user-defin-
able action, such as freeze, or change your aspect ratio for viewing DVDs 
(see page 40 to learn to program this button).
Previous and Next buttons allow you to navigate through your PowerPoint 
presentation while in Slide Show mode. Connect the USB connector on the 
provided computer cable to your computer to use these buttons. When you 
do this for the first time, the Add New Hardware wizard may appear. See 
page 16 for details on loading the correct USB drivers. Troubleshooting the remote
 Make sure the batteries are installed in the proper orientation and are 
not dead.
 Make sure you’re pointing the remote at the projector or the screen, not 
the computer, and are within the remote range of 15 feet (4.5m). For 
best results, point the remote at the screen.
 If you are trying to advance PowerPoint slides, make sure the USB 
cable is connected. If using a USB cable, make sure the correct drivers 
are installed.

The menus are grouped by usage:
 The Picture menu provides image adjustments.
 The Settings menu provides set-up type adjustments that are not 
changed often.
 The About menu provides a read-only display of information about the 
projector and source. 
Certain menu items may not be visible or may be grayed depending upon a 
particular source being connected. For example, Sharpness is only available 
for video sources and is not visible when a computer source is active. Menu 
options are grayed out only if the source if selected but no signal is present. 
For example, if the projector is set to a video source but the source, such as a 
DVD player, is turned off video menu options are grayed out.

Presets: Presets are provided that optimize the projector for displaying 
computer presentations, photographs, film images, and video images. Film 
input is material originally captured on a film camera, like a movie; video 
input is material originally captured on a video camera, like a TV show or 
sporting event. You can use the preset as a starting point, then further cus-
tomize the settings for each source. The settings you customize are saved in 
the preset for each source. To restore the factory default settings, choose Fac-
tory Reset in the Settings>Service menu (page 41). 
There is also a user-definable preset. To set a preset for the current source, 
adjust the image, select Save User in the Presets menu, then select Yes. You

Sharpness: (video sources only) changes the clarity of the edges of a video 
image. Select a sharpness setting.
Color Space: This option applies to computer and component video 
sources. It allows you to select a color space that has been specifically tuned 
for the input signal. When Auto is selected, the projector automatically 
determines the standard. To choose a different setting, turn off Auto, then 
choose RGB for computer sources, choose either SMPTE240, REC709 or 
REC601 for component video sources.
Color Temperature: changes the intensity of the colors. Select a listed rela-
tive warmth value. 
Color Control: allows you to individually adjust the gain (relative warmth 
of the color) and the offset (the amount of black in the color) of the red, 
green, and blue colors. 
Video Standard: when it is set to Auto, the projector attempts to automati-
cally pick the video standard based on the input signal it receives. (The 
video standard options may vary depending on your region of the world.) If 
the projector is unable to detect the correct standard, the colors may not 
look right or the image may appear “torn.” If this happens, manually select 
a video standard by selecting NTSC, PAL, or SECAM from the Video Stan-
dard menu.
Overscan: (video sources only) removes noise around the video image.
Sync Threshold Adjust: If a hardware device, such as a DVD player, is not 
syncing properly with the projector, select this option to help it to sync 
when connected to the projector.

Settings menuAudio: allows adjustments to Volume of the internal speaker and allows a 
chime to play when starting the projector. Adjustments can also be made 
from the projector ’s keypad and the remote. 
Sources: Power-up Source determines which source the projector checks 
first for active video during power-up. When the Autosource feature is On, 
the projector automatically finds the active source, checking the selected 
Power-up Source first. The source options are Computer 1 for a computer, 
progressive DVD, or HDTV source, and Video 1 (for S-video connections), 
and Video 2 (for composite video connections) for video sources. When this 
feature is Off, the projector defaults to the source selected in Power-up 
Source. To display another source, you must manually select one by press-
ing the Computer or Video button on the remote or keypad.
System>Rear: reverses the image so you can project from behind a translu-
cent screen. Ceiling: turns the image upside down for ceiling-mounted pro-
jection. Low Power: toggles between on and off. Turn it on to lower the light 
output of the lamp. This also lowers the fan speed, making the projector 
quieter. Display Messages: displays status messages (such as “Searching” or 
“Mute”) in the lower-left corner of the screen. Screen Saver Off: prevents 
your computer from going into Screen Save mode. Powe r  S ave: automati-
cally turns the lamp off after no signals are detected for 20 minutes. After 10 
additional minutes with no signal, the projector powers down. If an active 
signal is received before the projector powers down, the image will be dis-
played. After an additional 10 minutes with no signal, the projector powers 
down and can be toggled off. If an active signal is received before the projec-
tor powers down, the image will be displayed. When Power Save is 
enabled, Screen Save is disabled. Screen Trigger controls the 12 volt DC 
output switch on the connector panel. Screen Save automatically blanks 
the screen with a black color after no signals are detected for a preset num-
ber of minutes. The image returns when an active source is detected or a 
remote or keypad button is pressed.
