Pentax smc fa 2.8 100mm macro lens on K-70

Just bought used Pentax smc 2.8 100mm macro lens .Has 2 dials on the lens. One says focal range the other clamp off and on? On the LCD screen on my k70 where aperture no is displayed shows an F-- flashing. Whats going on?

Set the aperture ring to "A" (and use the camera controls to change the aperture), and set the clamp to off unless using manual focus. Then all should be well!

I use my F100 2.8 macro a lot with my K70. I don't bother with the limit switch. I forget the aperture ring sometimes due to the stick out of the logo lip.
