The auto idle is normal. When you start your engine you use a great gulp of juice from your batteries. My Tour Master does the exact same thing. Wait a few seconds, then press the red button. The flashing should stop and go back to the time.
Or, you can toggle to the engine panel and then toggle to the volts. It will show how many volts your generator is putting out. The panel will say "normal" at 14.0 volts.
The two antennas are for the radio and a CB. There is a coiled usable antenna where your L foot sits while you are driving. You can "peek" around the floor-dash partition and find the coiled antenna there. It hooks up to a CB nicely, and works well. I also located a non-used plug that provided the hot and ground for the CB.
