Replacing the Lamps
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 it has been used for approximately 1500
hours to ensure high projection quality. In the OSD Menu, you can check the lamp using time from the "OSD
Menu - Service". You should replace the lamp when the projected image is obviously darkened. Contact your
local dealer to purchase the authorized new lamp that suits to your projector.
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.
How to Replace the Projector Lamp
1. Turn off the projector and unplug the power cord. Wait for the projector, lamp and peripheral devices to
cool down. Then remove the lamp module.
Note: • When the projector is just turned off, the temperature of the lamp inside the projector is still very high (about 200~300°C).
You might be burnt if attempting to replace the lamp when the projector is not cooled off. The lamp can be replaced safely when
the lamp is cooled off.
