Replacing the Lamps
When a lamp reaches the end of it’s usable life, the following message is displayed. Re-
place the lamp.
The projection lamps should be replaced when they burn out. They should only be re-
placed with a certified replacement part, contact your local dealer if unsure.
Note:
1. Lamps are positioned differently. Take care not to force the lamps when replac-
ing.
2. Installation of both lamp modules (Lamp 1 and Lamp 2) is required to operate
the projector in dual or single lamp mode. If only a single lamp module is installed,
the projector's lamp will not turn on and will appear as a lamp failure
3. Lamps last approximately 2000-2100 hours (2500-2600 hours in Eco mode)
and the End of lamp life message is displayed during the lamps' final 100 hours of
operational life. Please replace during 2000-2100 hour.
Important:
1. The lamp contains a certain amount of mercury and should be disposed of ac-
cording to local ordinance regulations.
2. Avoid touching the glass surface of the new lamp: doing so may shorten its op-
eration life.
3. The lamp’s useful life ends and projector could not turn on over 2100 hours.
Please have the projector serviced.
