Resetting the total lamp timer
When replacing the lamp, reset the total lamp timer in the procedure below.

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.

Just when replacing the lamp, replace also the air filter with the one that comes with the lamp replacement kit.
