Replacing the Lamps
When a lamp reaches the end of it’s usable life, the following message is displayed. Replace the lamp.
The projection lamps should be replaced when they burn out. They should only be replaced 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 replacing.
2. Installation of both lamp modules (Lamp 1 and Lamp 2) is required to operate the projector in dual or sin-
gle 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 according to local ordinance
regulations.
2. Avoid touching the glass surface of the new lamp: doing so may shorten its operation life.
CAUTION
Lamp Handling Precautions
This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling
may result in accidents, injury, or create a fire hazard.
•
Lamp life may differ from lamp to lamp and according to the environment of use. There is no guar-
antee of the same life for each lamp. Some lamps may fail or terminate their life in a shorter period
of time than other similar lamps.
•
If the projector indicates that the lamp should be replaced, i.e., if LAMP 1 and/or LAMP 2 light up,
replace the lamp with a new one IMMEDIATELY after the projector has cooled down. (Follow care-
fully the instructions in the Lamp Replacement section of this manual.) Continuous use of the lamp
with LAMP 1 and/or LAMP 2 lighted may increase the risk of lamp explosion.
•
A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as
its lifetime draws to an end. Risk of explosion may differ according to the environment or condi-
tions in which the projector and lamp are being used.
If a lamps explodes, the following safety precautions should be taken:
Disconnect the projector’s AC plug from the AC outlet immediately. Contact an authorized service station
for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that there are
no broken shards or pieces of glass around the projector or coming out from the cooling air circulation
holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the pro-
jector except those who are authorized trained technicians and who are familiar with projector service.
Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to
do so, may result in an accident or injury caused by pieces of broken glass.
