Resetting the TOTAL LAMP TIMER

Resetting the total lamp timer
When replacing the lamp, reset the total lamp timer in the procedure below.
1 Connect the power cord.
Plug the power cord into the AC
socket of the projector.
Light source (lamp)
The lamp used for light source has a service life of about 1,000 hours. If the total operating time exceeds 900
hours, replace the lamp with new one (separately sold) as soon as possible. However, if the image becomes
dim or the colors get less crisp even before the total operating time does not exceeds 900 hours, also replace
the lamp. The lamp's total operating time can be checked on the screen. If noticeable color irregularities are
found after replacing the lamp, make the color irregularity correction on page 28.
CAUTION
Intense light hazard. Do not attempt to look into the aper ture and lens while the projector is operating.
As the usage environment can vary significantly, the projector lamp may not operate for 1,000 hours.
"1,000 hours" above indicates average life span and should be used for r eference only. This is different than the warranty period.
For safety, the power will not be tur ned on from the fourth times when turning on the power without changing the lamp after use for 1,000
hours.
