Maintenance
Cleaning the lens
1Turn the projector off and unplug the power cord.
2Slide open the lens cover, if the lens is covered.
3Apply 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.
4Lightly wipe the cleaning cloth over the lens in a circular motion.
WARNINGS: 
• Turn the projector off and unplug power cord before cleaning any part 
of the projector.
• Do not open any cover on the projector, except the lamp cover.
• Do not attempt to service this product yourself as opening and remov-
ing covers may expose you to dangerous voltage and other hazards.

Replacing the projection lamp
The lamp hours timer in the Projector Info menu counts the number of 
hours the lamp has been in use. Twenty hours before the lamp life expires, 
the message “Replace lamp” appears on the screen at startup.
•NOTE: Be sure to use the InFocus lamp module designed for this 
projector. 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. Use of non InFocus lamps may cause electrical 
shock and fire, and may void the projector warranty.  InFocus is not 
liable for the performance, safety or certification of any other lamps.
WARNINGS:
• The projector uses a high-pressure mercury glass lamp.  The lamp may 
fail prematurely, or it may rupture with a popping sound if jolted, 
scratched, or handled while hot.  The risk of lamp failure or rupture 
also increases as the lamp age increases; please replace the lamp when 
you see the “Replace Lamp” message.
• To avoid burns, allow the projector to cool for at least 60 minutes before 
you replace the lamp.
• Unplug the power cord before replacing the lamp.
• Do not drop the lamp module. The glass may shatter and cause injury.
• Do not touch the glass surface of the lamp module. Fingerprints can 
obscure projection sharpness and may cause the glass to shatter.
• 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. 
• When replacing the lamp while the projector is ceiling-mounted, wear 
protective eyewear to prevent eye injury.
• Hg – Lamp contains mercury. Manage in accordance with local 
disposal laws. See www.lamprecycle.org.
