Installers just left, installed my new 622. They cover the entire Tallahassee area, and they informed me I am the first person in Tallahassee to have a 622 professionally installed! Wheeeee! 
This is my question though. The 622 was working fine for about 5 minutes when it just turned off by itself. It turned on about 30 seconds later and worked fine for another few minutes before it turned itself off and then back on about 30 seconds later. It worked for another few minutes, then turned itself off again, and now it's been off for about 15-20 minutes. I tried hitting the power button once, but that does not turn the receiver on. Is this normal? Should I leave it alone? How long should I leave it alone for? It didn't warn me it was shutting down, it almost looked as if the receiver lost power, that's how abruptly it shut off.
