Hi Dan,
Thanks for the feedback.

Ideally I would like to reject it at the user (UI) level - is it possible to have co-dependent setting values, i.e. keypad lock has 2 possible values ("locked", "unlocked") if rx_mode is "normal" (not DW) and only "unlocked" if rx mode is not "normal", and similarly  for rx_mode ("normal", "cross mode" and "DualWatch"  when keypad is unlocked and only"normal" when teh keypad is locked)?

Otherwise, I would probably prefer just to have a comment stating that the radio will not unlock via its keypad when in DW etc.

Regards,
Ran
