8.5.10 CLO — Constant light output
CLO introduction
This function will ensure that the projector adjusts its illumination power to maintain the same level of output
light during the lifetime of the light source. This requires that the LED power is not set to 100% from the start,
but to a lower value. The lower this value is set, the longer the projector will manage to maintain the level. This
is due to the fact that the light source has a naturally decreasing intensity over time.
How to set the CLO
1. Enter the menu Installation/Illumination
Note:
The CLO feature is not designed to compensate the Iris adjustment. This means that if the CLO is set,
and the Iris is adjusted, it will affect the output light.
The illumination menu shows up

2. Set the desired power slider to an appropriate value, see “” , .
3. Select the CLO button in the menu by the arrow keys on the remote control, and activate by pressing
enter.
The output power will now remain constant
CLO scale slider
When the CLO button is enabled, the Desired power slider will be disabled, and by that not possible to adjust.
But if there is a short term need for further reduction of the output power, the CLO Scale slider can be used.
The output will then be reduced with a percentage in relation to the desired power value.
E.g.; if desired power is set to 80%, and CLO scale is set to 50%, the output power will be 40% of max.
This will enable the users to calibrate luminance, and not only laser power in both single and multi-channel
setup. This enables the CLO to maintain and adjust the light output. In multi-channel setup this make it
possible to be able to dim the entire image using the same scale value on all channels.
This functionality is particularly useful for multi-channel installations. Only available through API commands,
and is by that not accessible via the projectors User Interface.
