A reboot solves most of our problems. Aside from that, the only thing I've seen are the usual temporary signal losses, and an occasional satellite receiver misconfiguration that Salt Lake has to fix on their end.
However, if you're writing a guide, there are a lot of things that an operator can do to be better prepared beforehand, such as:
Know how to reboot, and make sure you can get into the cabinet quickly during a broadcast if needed.
Make sure you have quick way to look at the output of the receiver so you can verify if the problem is the receiver, or a problem with the building distribution system. I think most racks have a direct composite out available from the satellite. But I know that a lot of operators don't really understand that this is different than watching the modulated signal on a TV. In our building, I have a monitor wired directly to the monitor out on the receiver before it goes to any other equipment.
Make sure you have the SLC support number, and your receiver S/N & property number easily available. This info seems to have disappeared from some of the buildings I've worked on, and caused a little stress when it's needed.
Finally, since most signal loss problems are beyond our control (airplanes, solar flares, or whatever it is that knocks our signal), there's no reason to panic. If experiencing a signal loss, I usually wait a minute or so, and it will usually come back on its own, or sometimes with a reboot. There's really not much that an operator can realistically do on the receiving end, but it saves the operator a lot of stress if they know that...
Good luck with the guide.
