Andy - just want to say a huge thank you for all your help. I did a restart and it now seems to be working

The menu on mine isn't very intuitive. I found a diagnostic (61) and the keypads (option 1) showed 100% Comms but the RIO (option 2) 0%. Restart curiously was in 51 (parameters) and then option 17.

Anyway keypad now in new location and the restart seems to have done the trick.

Thanks once again

Lee.
