When switching from the dual mode to the single mode the lamp with the longest runtime is switched off.
If the runtimes are equal (if the projector has always been operated in dual mode) then lamp1 is switched out.
When switching to single mode, returning to the dual mode will not be possible in the
fi
rst 60 seconds,
Dual

The CLO menu
What is CLO?
Constant Light Output allows to force a constant light output (set in the
CLO Targets ...
menu) of the projector over a certain period.
This will eliminate uncontrolled light output drop caused by natural aging of the lamp. The light output is checked every 30 seconds
and if the target is not met, the CCD is adjusted.
If the CLO is disabled, there is no more automatic dimmer adjustment depending of the light output. In this mode, the light output
settings can be done manually.
In the illustration below, a normal light output curve is shown over the
fi
rst 1000 hours, image 7-115. By using CLO and setting the
target to 60% of the maximum light output, one will be able to operate during approximately 500 hours with a constant light output,
image 7-116.
