Using the menusTo open the menus, press the Menu button on the keypad or remote. (The 
menus automatically close after 60 seconds if no buttons are pressed.) The 
Main menu appears. Use the arrow buttons to move up and down to high-
light the desired submenu, then press the Select button. 
To change a menu setting, highlight it, press Select, then use the up and 
down arrow buttons to adjust the value, select an option using radio but-
tons, or turn the feature on or off using check boxes. Press Select to confirm 
your changes. Use the arrows to navigate to another setting. When your

ceeding menu; press the Menu button at any time to close the menus. 
Dots appears before the menu name. The number of dots indicate menu’s 
level, ranging from one (the Main menu) to four (the most nested menus). 
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 present you with intensity configurations optimized for the 
input source. You can select a preset configuration that has been specifically 
tuned for either Presentation, Photography, Film, and Video (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.) Your viewing preferences may vary. Cycle through the preset inten-
sity configurations and pick the one you like the best.
Presets are user-definable. You can use the preset as a starting point, then 
further customize the settings for each source. The settings you customize 
are saved in the preset for each source. To restore the factory default set-
tings, choose Factory Reset in the Settings>Service menu (page 36). 
To set a preset for the current source, adjust the image, select Save User in 
the Presets menu, then select Yes. You can recall these settings in the future

cent screen. Ceiling turns the image upside down for ceiling-mounted pro-
jection. Display Messages displays status messages (such as “Searching” or 
“Mute”) in the lower-left corner of the screen. NND prevents your notebook 
computer from going into Screen Save mode if the USB cable is connected.

MaintenanceCleaning the Lens1
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
 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.
Replacing the Projection LampThe lamp hours used timer in the About menu counts the number of hours 
the lamp has been in use. After approximately 3,980 hours, the message 
“Change lamp” appears on the screen at startup. If the maximum lamp time 
of up to 4,000 hours is exceeded, the lamp will not light. In this case, after 
replacing the lamp you must reset the lamp hours by simultaneously press-
ing both Vo l u m e buttons on the projector ’s keypad and holding them for 10 
seconds.
NOTE: You can order new lamp housings from your dealer. See “Accesso-
ries” on page 40 for information. Use only a replacement lamp with the 
same type and rating as the original lamp.1
Turn off the projector and unplug the power cord. 
2
Wait 30 minutes to allow the projector to cool thoroughly.
3
Turn the projector on its side so that the lamp door is facing you. Using a 
flat-blade screwdriver, gently pry the lamp door from the projector by 
placing the screwdriver blade into the space between the top of the lamp 
door and the projector.

Loosen the two captive screws that attach the lamp housing to the pro-
jector.
5
Detach the lamp connector from the projector by depressing the locking 
tab on the connector and lightly pulling it free.
WA R N I N G:
To avoid burns, allow the projector to cool for at least 30 minutes 
before you replace the lamp.
Do not drop the lamp housing or touch the glass bulb! The glass 
may shatter and cause injury.
Be extremely careful when removing the lamp housing. In the 
unlikely event that the bulb ruptures, small glass fragments may be 
generated. The lamp housing is designed to contain these frag-
ments, but use caution when removing the lamp housing.
6
Carefully remove the lamp housing. Dispose of the lamp in an environ-
mentally proper manner. 
7
Install the new lamp housing and tighten the screws.
8
Re-attach the lamp connector to the projector. The locking tab should 
engage when the connector is fully plugged in.
9
Replace the lamp door.
10
Plug in the power cord and toggle the Powe r switch to turn the projector 
back on.

Cleaning the Lamp Housing ScreensIn dirty or dusty environments, the two dust filter screens in the lamp hous-
ing can become clogged, causing high temperatures and premature lamp 
failure. Routine maintenance to remove dust from the screens lowers the 
lamp operating temperature and prolongs lamp life. To maximize lamp life 
you should clean the screen every 250 hours. 1
Remove the lamp housing. 
2
Examine the dust filter screens on the lamp housing. If necessary, use a 
vacuum cleaner set on low power to clean the screens. Be careful not to 
disturb any internal components when cleaning the screens.
3
Replace the lamp housing and lamp door.
Using the security lockThe projector has a security lock for use with a PC Guardian Cable Lock 
System. If you have a PC Guardian Cable Lock System, refer to the informa-
tion that came with the lock for instructions on how to use it.
