K-5 autofocus with FA50 mm F1.4

I'm pretty much an enthusiastic but clueless amateur. Got a FA50 mm F1.4 lens (pentax # 20817) and plugged it into my K-5.
The camera refuses to do anything besides keep blinking the following string, on the mall green upper left display and on the main one:


No, I don;t think it's a nasty abbreviation. It probably has to do with focus.

Any ideas?

1. Rotate your aperture ring to the A position. You need to press the little button on the ring to get all the way there. Your lens will now work fine.

2. Go into the camera menu and find the setting "set aperture ring to permitted" or something along those lines. Choose option 2 - Permitted. You can now use manual aperture lenses on your camera with stop down or green button metering.

Congratulations. You have now passed the first test. There will likely be others. Believe me, many of us on this site have been equally clueless on points like this. It's happened to me...Steinback - good job breaking t-arad in.
