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” displays 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.
• Do not touch or block the projector lens with any objects as this can damage 
the projector lens. Scratches, gouges and other lens damage are not covered 
by the product warranty. 
• 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.
