From the user manual:
Antenna configuration is a one time procedure that MUST BE COMPLETED before using your King-Dome antenna. Configuration may be done with the supplied wall mount controller or the #1844 Keypad
King Controls "loaned" me the 1844 keypad ($200) refundable deposit and then talked me thru the reprogramming procedure.
After I was sure it was working with my DISH receiver, I returned the keypad and got my deposit back. It was fairly simple to do.
The other option is to find a RV repair facility (mobile?) that has the tool and pay them to do it for you.
