Learn how to configure a laser file and use the projector's LiteLOC
Use the laser file to control the power settings of the red, green, and blue (RGB) lasers. The LiteLOC
feature ensures that color and brightness are held at the level you set.
Create multiple laser files to manage varying screen sizes, brightness requirements, room
temperatures in the projection booth, and types of content (such as 2D, 3D, and alternative content).
Creating a new laser file for CP4415-RGB,
CP4420-RGB, CP4425-RGB, and CP4435-RGB
Create a laser file to store the power settings for the RGB laser light source and the maximum
expected room temperature for the projection booth.
To ensure color and brightness are held at the required levels for your installation, enable LiteLOC for
each laser file you create. If you make significant change to the brightness level when refining the
laser power settings, it takes a few minutes for the color and brightness to stabilize.
1. Log in as service.
2. Turn the laser on.

point.
