Video Standard: when set to Auto, the projector attempts to automatically 
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. 
Active Iris: when on, the projector monitors the image brightness and mod-
ifies the light output if the image is dark, which improves black levels. In 
Presentation mode, it looks at peak brightness, in Theater mode it looks at 
average brightness.
Overscan: (Computer 1 and video sources only) removes noise around the 
video image.
The following 4 options are for computer sources only: 
Phase: adjusts the horizontal phase of computer 2, 3 and component (except 
480i and 576i) sources. 
Tr a c k i n g: adjusts the horizontal scan of a computer source (except Com-
puter 1).
Horizontal / Vertical Position: adjusts the position of a computer source 
(except Computer 1) and Video 1 source (except 480i and 576i).
Computer 2: allows you to turn Sync on Green on for this source.
Computer 3: allows you to turn Sync on Green on for this source..

Settings menuAudio: allows adjustments to the volume. Also allows you to turn on and 
off the Internal speakers and assign a particular source to a specific audio 
input. If your HDMI source has problems with its audio stream, you can 
mute it by selecting HDMI Noise Cancel. 
Sources
: allows you to assign a particular input to a specific source key 
when using the remote. Also allows selection of a default Startup Source 
and enables or disables Autosource. 
Sources>Power-up Source: this determines which source the projector 
checks first for active signal during power-up. 
Sources>Autosource: When Autosource is not checked, the projector 
defaults to the source selected in Powerup Source. If no source is found, a 
blank screen displays. When Autosource is checked, Powerup 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. 
System>Rear: reverses the image so you can project from behind a 
translucent screen.
Ceiling: turns the image upside down for ceiling-mounted projection.
WARNING: To prevent eye injury if the projector is ceiling mounted, 
wear protective eyewear before opening lamp door. A warning sticker is 
included with the user documentation. Place this sticker on the lamp 
door if the projector is mounted on the ceiling.
IR Receivers: turns individual IR receivers off or on to avoid environ-
mental interference.
Auto Power: When Auto Power is checked, the projector automatically 
goes into the startup state after the projector is powered on. This allows 
control of ceiling mounted projectors with a wall power switch.
Display Messages: displays status messages (such as “Searching”) in the 
lower-left corner of the screen.
Low Power: toggles between on and off. Turn it on to lower the light out-
put of the lamp. This also lowers the fan speed, making the projector qui-
eter.PC Screen Saver Off: prevents your notebook computer from going into 
Screen Save mode. The projector must be connected to the PC via a USB 
cable for this feature to work.

Pow e r  S av e: automatically 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 projec-
tor powers down, the image will be displayed. 
Screen Save: automatically blanks the screen after no signals are 
detected for five minutes. The image returns when an active source is 
detected or a remote or keypad button is pressed. Screen Save is disabled 
when Power Save is enabled.
Startup Logo: allows you to display a blank Black, White, or Blue screen 
instead of the default screen when no source is detected at startup. It also 
allows you to capture and display a custom startup screen. 
To capture a custom logo, display the image you want to capture on your 
computer and select the Capture New option. From the Capture New 
menu, use the Capture Position X and Capture Position Y adjustments to 
frame the logo to be captured. Press Capture Start in the Capture New 
menu. The projector will let you know if the capture was a success or a 
failure.
The next time you start the projector, the custom logo you captured dis-
plays.

Blank button on an optional remote.

NOTE: You can order new lamp housings from www.infocus.com (in select 
areas), your retailer or your dealer. Only genuine InFocus lamps are tested 
for use in this projector. InFocus is not liable for the performance, safety or 
certification of any other lamps. The use of other lamps violates the projec-
