this may sound like an odd question but what do you do for a living?
I dont know risco but i believe the rf settings are quite critical in that menu.
Also in risco's defence its not designed to be end user friendly in the engineer bits, good installers train on their preferred kit from the manufacturer. While i dont rate it, its still a decent bit of kit but far from diy. Im suprised you have had the help so far from risco.
