Thanks, guys. The "Activate" info online appeared right after the UPS delivery confirmation went online. It seems strange that the 622 came by UPS, but the return label on the flipside is FedEx. Guess they're spreading the wealth.
Following their instructions on the inclosed sheet, it took about 15 minutes to download and install what it needed until the "Activate Now" message appeared. The activation on the web took only a minute, but then it went through the whole routine again. Including checkswitch and program guide download times it added another 15 minutes. Then when I went to create some timers I found it only had 48 hours of guide. It would not go past Sunday night at 6. It didn't offer to update the guide, so the only way I knew of to force it was another check switch. With the checkswitch, power on delay, and guide download, it was another 12 minutes. I don't remember it being quite so tedious the last few replacements. It also downloaded 2- 5 minute videos of how-to, and the Dishmas greeting.
But alas, all is well in DishLand.
