Replacing the Light-source Lamp (Cont.)
Resetting the Lamp Use Time
After replacing with a new light-source lamp, reset the counter inside the projector. This works to reset the life calculation of the
light-source lamp, allowing the used time of the new light-source lamp to be accumulated.

To check the lamp use time has been reset :
You can check it by LAMP TIME on the OPTIONS menu.
After replacing with a new light-source lamp, be sure to
reset the lamp use time. When the lamp use time
indicates 1000 hours, and if it is not reset, the projector
does not operate. (The light-source lamp does not turn
on.)
Reset the lamp use time only when you have replaced
with a new light-source lamp. Never reset it at a halfway
time. Otherwise, the replacement time may become
unclear, degrade performance markedly, or cause lamp
explosion.
