PiP (Picture in Picture) allows you to overlay a smaller window 
showing the video source on top of the larger computer source 
window. You must have both a computer and video source con-
nected to use PIP. You can’t show a computer image in the 
smaller PiP window, only a video image. You can select a small,

MAINTENANCE & TROUBLESHOOTING
This section describes how to:
clean the lens
clean the lamp filter screens
replace the projection lamp 
replace the batteries in the remote
use the security lock feature
troubleshoot the projector
Cleaning the Lens
Follow these steps to clean the projection lens:
1Apply 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, sol-
vents or other harsh chemicals might scratch the lens.
2Lightly wipe the cleaning cloth over the lens in a circular 
motion.
3If you don’t intend to use the projector immediately, replace 
the lens cap.
Cleaning the Lamp Filter Screens
In dirty or dusty environments, the dust filter screens on and 
around the lamp module can become clogged, causing high tem-
peratures inside the lamp module. These high temperatures can 
cause premature lamp failure. Routine maintenance to remove 
dust and dirt from the screens lowers the lamp operating temper-
ature and prolongs lamp life. To maximize lamp life you may 
want to clean the screen every 250 hours.
1Remove the lamp module. Refer to “Replacing the Projection 
Lamp” on page 30 for instructions.
2Examine the dust filter screens on the lamp module and in the 
lamp housing area. 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.
3Replace the lamp module.

Maintenance & Troubleshooting
Replacing the Projection Lamp
WARNING: To avoid burns,
allow the projector to cool for at
least 60 minutes before you
replace the lamp. Never extract
the lamp housing while the
projector is operating.
The lamp hour timer in the Service Info menu counts the number 
of hours the lamp has been in use. When the timer reaches 2900 
hours, the Lamp LED lights red, indicating that it is time to 
change the lamp. You can order new lamp housings from your 
InFocus dealer. See “Accessories” on page 37 for information.
Follow these steps to replace the projection lamp:
1Turn off the projector and unplug the power cord. 
2Wait 60 minutes to allow the projector to cool thoroughly.
3Turn the projector upside down and loosen the captive screw 
on the lamp door. The lamp door is part of the lamp housing.
WARNING: Be extremely careful
when removing the lamp housing.
In the unlikely event that the bulb
ruptures, small glass fragments
may be generated. The lamp
module is designed to contain
these fragments, but use caution
when removing the lamp module.
Before replacing the lamp, clean
the lamp compartment and
dispose of cleaning materials.
Wash hands after lamp
replacement. This product has a
lamp which contains a very small
amount of mercury. Dispose of it
as required by local, state or
federal ordinances and regulations.

Maintenance & Troubleshooting
Replacing the Batteries in the Remote Control
The life of the batteries depends on how often and how long you 
use the remote. Symptoms of low battery charge include erratic 
responses when using the remote and a reduced range of opera-
tion.
1Turn the remote face down in your hand.
2Slide the door off the end of the remote.
3Remove the old batteries and dispose of them in an environ-
mentally proper manner.
4Install two new AA alkaline batteries. Make sure you install 
each in the correct direction.
5Re-install the door.
Using the Security Lock 
The projector has a security connector for use with a PC Guard-
ian Cable Lock System (Figure 27). See “Accessories” on page 37 
for ordering information. Refer to the information that came with 
the lock for instructions on how to use it.
