sound.

AC Power On: When this feature is on, the projector automatically turns on 
when electrical power is connected. This allows control of ceiling mounted 
projectors with a wall power switch.
Auto Off Time: automatically turns the projector off after no signals are 
detected for a preset number of minutes. If an active signal is received 
before the projector powers down, the image will be displayed.
Screen Save Time: automatically blanks the screen with a black color after 
no signals 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.
Lamp 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.
Power Sounds: controls whether the projector makes a sound when 
powered on and off.
Auto Source: When this feature is On, the projector automatically finds the 
active source, checking the selected Power-up Source first. 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 
pressing the Source button on the remote or keypad.
Power-up Source: determines which source the projector checks first for 
active video during power-up.
HDMI DDC: When this feature is set to On, the projector will support an 
older DVD player for HDMI port.
Video Standard: When this feature is 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 Standard menu.
Closed Captions: controls closed caption display while audio is not muted. 
If this setting is not off, and audio is not muted, and the source is NTSC and 
contains captions on the selected channel, then the projector must display 
caption text overlaid on the image.
Ceiling Mount: turns the image upside down for ceiling-mounted 
projection.

Save mode. The projector must be connected to the PC via a USB cable for

screen at startup, and when no source is detected.
Take Snapshot...: Captures the current image and allows it to be used as 
the startup screen image.
Blank Screen Color: determines what color is displayed when you press 
the Blank button on the remote.

lower-left corner of the screen.

items.

image behind the menu you can see. As the value increases, more of the 
image behind the menu is visible.
Magnify Controls: determines whether the select key can be used to change 
magnify settings when the OSD menu is not visible.
PIN Protect: The PIN (personal identification number) feature allows you 
to password protect your projector. Once you enable the PIN feature, you 
must enter the PIN before you can project an image. The default PIN on this 
projector is Menu-Up-Down-Select-Source. Use the navigation buttons on 
the remote or keypad to enter the correct 5-button press sequence. When all 
5 numbers are entered correctly, press the Select button on the remote or 
keypad to select OK. If the message “Wrong PIN” appears, verify the code and re-enter it. If you mis-enter a number, you must enter 5 numbers and 
press the Select button in order to access the “Wrong PIN” message and re-
enter the code.
To enter the PIN at projector startup:
Power up the projector. The “Enter PIN” dialog box appears after the 
startup screen. Enter the PIN. Use the navigation buttons on the remote or 
keypad to enter the correct button press sequence. See the description above 
for instructions.
To change the PIN:
Select “Change PIN...” in the Setup menu. Enter the existing PIN. Enter the 
new PIN. You can navigate between OK and Cancel by pressing the up and 
down buttons on the keypad. Select OK or Cancel by pressing the Select 
button. Verify the new PIN.

Cleaning the lens

cleaner directly to the lens. Abrasive cleaners, solvents or other harsh 
chemicals might scratch the lens.
2Lightly wipe the cleaning cloth over the lens in a circular motion.

System. Refer to the information that came with the lock for instructions on 
how to use it.

hours the lamp has been in use. Twenty hours before the lamp life expires, 
the message “Change lamp” appears on the screen at startup.
•NOTE: You can order new lamps 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 projector warranty and voids all certification marks 
on this projector.

• 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. Before replacing a ruptured lamp, clean 
the lamp compartment and dispose of cleaning materials. Wash hands 
after lamp replacement. If replacing the lamp while the projector is 
ceiling-mounted, wear protective eyewear.
Hg – Lamp contains mercury. Manage in accordance with local 
disposal laws. See www.lamprecycle.org.
4Loosen the captive screw that attaches the lamp housing to the 
projector. Carefully remove the lamp housing. Dispose of the lamp in an 
environmentally proper manner.

6Re-attach the lamp connector to the projector.
7Replace the lamp door by sliding it into place.
8Plug in the power cord and press the Power button to turn the projector
