In one of the most masterful ever trades in the market of human barter, I traded the offer to help teach a recent RV-12 builder how to use his Garmin 496 and perhaps assist in the calibration of the autopilot in exchange for a little flying time. I got my 1.3 hours, he now knows how to get from A to B with his Garmin, and as an added bonus I recalibrated the trim indicator. However, I completely failed at the AP config. Following the manual, I started with AP Servo Configuration on page 8-14.
Step 1 - Configure DSAB was easy. Step 2- Servo Calibration and Servo Test was not.
Quoteth the guide: If Airspeed Color Thresholds have not been configured, Servo Calibration and Servo Test cannot proceed. Page 5-4 is referenced for performing that configuration. Page 5-4 has me look for the IASCLR menu item. I couldn't find such a menu item. Searching this forum, I think I found out why:
Any help appreciated!

The problem is that when I go back to page 8-15 / 8-16 press the disconnect switch to continue (after seeing the message that "2 servo(s) found...", nothing happens. There should be more onscreen instructions according to the guide, but I never get any response at all when pressing the disconnect button.What those customizations do enable are presetting of many of the RV-12 airframe and configuration parameters. A subset of those are also unable to be adjusted from the setup menu. This includes things like IAS colors, where the OAT is connected, how the serial altitude encoder should transmit altitude to the transponder, the IAS/altitude units, and other things of that nature.
Any help appreciated!
