OptiCal (Primary Lens Calibration): OptiCal provides the ability to store and recall
focus, zoom and position settings for the primary lens.

To enable OptiCal:

Select Installation from the Main Menu.

Select Geometry and Color from the Installation menu.

Select OptiCal from the Geometry and Color menu.

Press ENTER to check the box labeled OptiCal.

Press EXIT to exit the Geometry and Color menu.

Select Calibration and Test Patterns from the Installation Menu.

Select OptiCal from the Calibration and Test Patterns Menu.

OptiCal gives you a choice of three types of lens calibrations:

• A Reference calibration establishes a reference point (starting position) for measuring

relative lens movement. All distances are measured from this reference point.
A reference calibration is lost when power is removed from the projector and occurs on
every power-up as long as OptiCal is enabled.

• A Motion calibration determines the characteristics of each motor and values are

saved in the projector’s memory. If OptiCal is enabled and a motion calibration has
previously been done, the projector automatically recalls these settings from memory
when it’s being powered up and a motion calibration will not take place.

• A Full calibration performs both a Reference calibration and a Motion calibration.

If no calibration has previously been done you may be prompted to do a Full calibration. If
a motion calibration has been done, you will be prompted to complete a reference
calibration. If both calibrations have been done, the OptiCal checkbox is checked and
OptiCal enabled.

When OptiCal is enabled, the VX-44d/-55d performs a reference calibration when the
projector is turned on. The lens returns to its last saved position (or actual position, if no
motion calibration has been done previously). Further adjustments to the zoom, focus and
position are automatically saved.

1. OptiCal control is a preference setting and is retained between

power cycles.

2. OptiCal has no effect on the secondary anamorphic lens, only

the primary lens.
