Function Key Re-mapping

[Smudge617]

I want to switch the functions on F2 and F9 over on my Accurascale class 37's. I've read the ESU manual and TBH I'm more confused than when I started, can anyone explain in idiot proof terms how I go about doing this, what CVs do I change etc.

Are you really sure you want to map drive hold to the horn?

Amended my original post.

But yes, seem Accurascale are using different keys, F7 is drive hold, F2 is brake and F9 is the two-tone horn.

Honestly, the best thing is just to put weights on the booklet's leaves to keep it open, and begin to push buttons per the directions. If you screw up, just perform a reset of the command module.
