Managing the light
source
Learn how to configure a laser file and use the projector's LiteLOC
™
feature.
The laser file allows you 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.
You can 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 and
CP4420-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.
The maximum (MAX) power limit for Red and Green changes according to the value set for the
maximum expected room temperature. For Red, Green, and Blue power levels, system stability may
be affected if levels are set below the minimum (MIN) power limit shown.
To ensure color and brightness are held at the required levels for your installation, Christie
recommends enabling LiteLOC for each laser file you create.
When refining the laser power settings, the amount of time required to re-stabilize the projector
depends on the size of the adjustment. For very small adjustments to the expected room temperature
or power settings, the projector requires only 1 or 2 minutes to re-stabilize. For larger adjustments,
the projector may require up to 15 minutes to re-stabilize.
