the lamp unit has been replaced with a new

Timing of lamp unit
replacement
The lamp used for the light source has its due life. The
life of light source lamp used in the main unit is 1 500
hours
(when lamp output is HIGH and lamp
1
selection is DUAL). However, it may happen that the
lamp becomes dead (will not light) by the time of 1 500
hours
depending on the characteristics of individual
1
lamps and working conditions (lamps may reduce their
life affected by the times of lighting and the intervals
between previous lighting and next lighting). Therefore,
it is strongly recommended for the user to keep a
spare bulb.
If your lamp unit is not replaced after 1 300 hours
(with the lamp output set at "HIGH"), power supply will
be turned off automatically at the time of 1 500 hours
entering a standby state. After 1 500 hours
lighting, power supply is turned off automatically about
10 minutes later, entering a standby state even if it is
turned on again.

"HIGH")

hours
