DITHER is a legacy Allegiant receiver/driver feature designed to extend the life of
tube-based low-light level cameras. Its function was to prevent bright lights in the

the receiver/driver, and is controlled by the auxiliary 5 function. To activate the
DITHER function, turn [ON] auxiliary 5. To deactivate the feature, turn OFF auxiliary
5. When first enabled, the pan/tilt unit makes one short left/right cycle to indicate
