Maintenance
Replacing the lamp
Depending on the lamp model, the lamp life is affected by the installation method and 
frequency of the lamp on/off operation. It is suggested to replace the projector lamp when 
the lamp is used for approximately 2500 hours to ensure high projection \
quality. In the 
OSD Menu, the lamp using time can be checked from the "OSD Menu - SERVICE". The 
lamp should be replaced when the projected image is obviously darkened. \
Contact your 
local dealer to purchase the authorized new lamp suitable for your proje\
ctor.
Note:
• Purchase the lamp module produced by Vivitek. Using the lamp that is not made by Vivitek may affect the 
performance of the projector or damage the projector.
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 guarantee-tee 
of the same life for each lamp. Some lamps may fail or terminate their l\
ife 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, re-
place the lamp with a new one IMMEDIATELY after the projector has cooled down. (Follow carefully 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 conditions in which the 
projector and lamp are being used.
•  If a lamp 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 
projector except those who are authorized trained technicians and who ar\
e 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 gl\
ass.
•  The projection lamp should be replaced when it burns out. It should only be replaced with a certified 
replacement part, which you can order from your local dealer.
Warning:
• Be sure to turn off and unplug the projector at least 30 minutes before replacing the lamp. Failure to do so 
could result in a severe burn.
•  Safety glasses should be worn when replacing the lamp while the projecto\
r is ceiling mounted
