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. 
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. 
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 Ceiling: automatically senses when the projector is inverted and turns 
the image upside down. This is On by default.
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.
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. 
Screen Save: automatically blanks the screen with a black color after no sig-
nals are detected for a preset number of 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.

Cleaning the dust filtersThe dust filters catch dust and other particles in the air. If the filters become 
clogged, the projector does not cool properly and may malfunction. In dirty 
or dusty environments, they should be cleaned after every 100 hours of use. 
Failure to do so may result in premature lamp failure. 
There are two filters, one mesh filter attached to the dust filter door and one 
metal grid filter adjacent to the lamp door. 1
Turn off the projector and unplug the power cable. 
2
Wait 60 minutes to allow the projector to cool thoroughly.
WA R N I N G: To avoid burns, allow the projector to cool for at least 60 
minutes before you clean or replace the dust filter.
