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 chiller setpoint 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.
1. In the left navigation pane, tap Laser Settings > Laser Power/LiteLOC Setup.
2. To activate the controls, tap the Display White Test Pattern slider.
3. To create a new laser file, tap Create.
4. In the Create dialog, type a name for the new laser file and tap Create.
5. If the laser file will be associated with a 3D channel, tap the 3D Sync slider.
6. Under Chiller Setpoint, tap the plus and minus signs (or drag the temperature slider) to
indicate the maximum setpoint temperature.
The system uses the maximum setpoint temperature to calculate the light output. The default
chiller setpoint value is 24°C. A lower setpoint generally results in increased brightness and
better efficiency. A higher setpoint will reduce the maximum power setting available for the
lasers. The chiller setpoint temperature must reflect actual operating conditions.
7. Set the approximate Red, Green, and Blue power levels as required for your projection
environment and allow the projector to stabilize for 15 minutes.
System stability may be affected if you set a power level below the minimum power level
recommended.
When setting the Red or Green power level, Christie recommends setting a level below the
maximum (MAX) limit shown. A value below the maximum limit ensures an optimal brightness
that can be maintained over time.
8. If color or brightness is not at the target level, refine the Red, Green, and Blue power settings
to achieve the target, and then allow the projector to re-stabilize for an additional 3 to 5
minutes.
The projector is considered stable when there are no further adjustments and you obtain the
same screen state results after two sets of measurements, 5 minutes apart.
9. Once the correct color and brightness are achieved and the projector has stabilized, tap the
LiteLOC slider to lock the settings.
The color of the slider turns to green to indicate the settings are locked. The projector's
LiteLOC
™
system maintains the brightness and color levels.
10. To save the new laser file, tap Save.
Color sensor (CSense) data are displayed on the interface to provide feedback on the current
color sensor information.
