Presets: The provided Presets optimize the projector for displaying com-
puter 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. 
There are also three user-definable presets. To set a preset for the current 
source, adjust the image, then choose Save User 1, 2, or 3. You can recall 
these settings in the future by selecting the appropriate user presets. 
Room Lighting: This features optimizes the projector for your room’s light-
ing conditions. Select Dark if you are in a dark room, Light if in a bright 
room. Choosing Light maximizes the light output from the projector.

Settings menuAudio: allows adjustments to the volume, bass, treble and balance. Also 
allows you to turn on and off Loudness (which boosts the higher and lower 
frequencies), the Internal speakers, and projector startup Chime.
Sources
: allows you to assign a particular input to a specific source key 
when using the optional Integrator remote. Also allows selection of a 
default Startup Source and enables or disables Autosource and RGB. 
Sources>Startup Source: this determines which source the projector 
checks first for active video during power-up. 
Sources>Autosource: When Autosource is not checked, the projector 
defaults to the source selected in Startup Source. If no source is found, a 
blank screen displays. When Autosource is checked, Startup Source deter-
mines which source the projector defaults to at power-up. If no signal is 
present, the projector checks the sources in order until a source is found or 
until power down. 
Sources>RGB Video: check this box if you are using a DVD player with 
RGB output.
System>Rear: reverses the image so you can project from behind a translu-
cent screen.
Ceiling: turns the image upside down for ceiling-mounted projection.
Auto Power: When Auto Power is checked, the projector automatically 
goes into the startup state after the projector is powered on. This allows con-
trol of ceiling mounted projectors with a wall power switch.
Display Messages: displays status messages (such as “Searching” or 
“Mute”) in the lower-left corner of the screen.
Low Power: (C420 only) toggles between on and off. Turn it on to lower the 
light output of the lamp. This also lowers the fan speed, making the projec-
tor quieter.
Pow e r  S av e: automatically turns the lamp off after no signals are detected 
for 5 minutes. After 3 additional minutes with no signal, the projector pow-
ers down. If an active signal is received before the projector powers down, 
the image will be displayed.

panel. See page 6 for details.
Startup Logo: allows you to display a blank Black, White, or Blue screen 
instead of the default screen at startup and when no source is detected. It

computer, highlight Capture New, then press Select twice. While the cap-
ture is underway, the LED on the keypad turns orange. When ready, the 
projector confirms the capture and the LED changes to green.

zoom the image, press the right mouse button to decrease the magnifi-
cation. You can use the cursor control to pan the image, displaying dif-
ferent parts of it (only if the image is magnified). To return to the 
original size and cancel Zoom, press the Effect button a second time.
About: displays the About menu.
PiP: (Picture in Picture) allows you to overlay a smaller window show-
ing the video source on top of the larger computer source window. You 
must have both a computer and video source connected to use PIP. You 
can’t show a computer image in the smaller PiP window, only a video 
image. You can select a small, medium, or large window. You can also 
move the PiP window on the screen using the PiP Position X and Y 
options in the menu. Press the up and down arrows to change the posi-
tion.

Avoid using an excessive amount of cleaner, and don’t apply the 
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh 
chemicals might scratch the lens.
2
Lightly wipe the cleaning cloth over the lens in a circular motion. If you 
don’t intend to use the projector immediately, replace the lens cap.
Changing the lensOptional long throw and short throw lenses are available. See “Optional 
Accessories” on page 41 for ordering information.1

WARNINGS: 
 To avoid burns, allow the projector to cool for at least 60 minutes before 
you replace the lamp.
 Do not drop the lamp module. The glass may shatter and cause injury.
 Do not touch the glass lamp screen. Fingerprints can obscure projection 
sharpness.
 Be extremely careful when removing the lamp housing. In the unlikely 
event that the lamp ruptures, small glass fragments may be generated. 
The lamp module is designed to contain most of these fragments, but 
use caution when removing it.5
Carefully remove the lamp module by grasping and lifting the metal 
bail wire. Dispose of the lamp in an environmentally proper manner. 
6
Install the new lamp module, making sure that it is properly seated.

Tighten the three screws.
8
Replace the lamp door by inserting the tabs into the tab bays and tight-
ening the two screws.
