Scanning Functions
Operation of the scanning functions depends on the kind of receiver or pan/tilt mechanism you have and the operating mode of your keyboard (CM6700 or Direct Mode).
There are four types of scanning functions: auto (moves camera back and forth between stops), random (moves camera in a random pattern), frame (moves camera back and forth in 10 degree steps), and preset (sequences camera through all programmed presets, pausing between each).
Operate scans according to Table F.
