11.2 Lamp power mode
What can be done?
The lamp power mode can be switched betweenNormalandEconomic. When playing in Economic mode, the lamp life time will
be higher than in normal mode.
The counter of the lamp life time counts equal for normal or economic mode but the customer will see that the ageing of the lamp is
lower in economic mode.
Normal : maximum allowed power is fed to the lamp. Maximum light output is reached in this way.
Economic : a reduced wattage is fed to the lamp. Reduced light output but a longer life time for the lamp.
The lamp power mode setting is linked with the CLO mode setting. When CLO mode settings is set toOn, the lamp power mode
setting is ignored and projector will play in CLO mode. Once the CLO mode setting is switched toOff, the installed lamp power
mode setting will be used.
How to switch
1. PressMenuto activate the menus and selectLamp→Power→Mode.

11.4 Auto dimming when on Pause
About auto dimming when on pause
When the projector is switched to pause, the shutter is closed but the lamp is still running on full power. When auto dimming on
pause is activated, then the lamp power will be reduced from its current value to its minimum value. When returning out of pause
the lamp power is restored to its previous value.
How to set up
1. PressMenuto activate the menus and selectLamp→Power→Auto Dimming when Pause.

11.5 Auto dimming when No Signal
About auto dimming
When no signal is detected on the selected input the lamp power will be reduced from the current value to its minimum value. When
the input signal is re-detected, the lamp power is restored to its original value.
This function is a duplicate of the Auto dimming in the Input menu.
How to set up
1. PressMenuto activate the menus and selectLamp→Power→Auto Dimming No Signal.

11.7 CLO mode (Constant light output mode)
What can be done?
Constant Light Output allows to force a constant light output (set in theCLO Target lumensitem) 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 5
minutes, if the target is not met, the lamp power is adjusted.
Setting CLO off means that the lamp will operate at constant power (no power adaptation to meet constant light output).
In the illustration below, a normal light output curve is shown over thefirst 1000 hours, image 11-16. Byusing 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,
