9. Perform a lens HOME & RETURN operation. (See user guide of the "Communicator" chapter Installation >
Advanced > Lens parameters)
Note: The HOME & RETURN operation enables the projector to determine the reference positions of
the motorized ZOOM and FOCUS of the installed lens.
For the lenses with a focus adjustment mounted on the lens (4K lenses) , the lens holder goes to a
normal (fixed) focus position. For these lenses, do not mechanically adjust the focus position of the
lens holder, otherwise the normal position will be lost.
A Spatial Color Calibration (SCC) has to be execute in case of a first install or in case a High
Brightness lens is swapped with a High Contrast lens or vice versa. See user guide of the
Communicator for detail SCC calibration instructions.
CAUTION: Never transport the projector with a Lens mounted in the Lens Holder. Always remove
the Lens before transporting the projector. Neglecting this can damage the Lens Holder and Prism.
