I'm probably missing something (because I haven't tried it)....
Consider this theoretical scenario...
* A
stop button is labelled as
record in the documentation.
* When you press the
stop button it goes into record mode even though clearly there is a stop icon you are pressing and nothing goes red.
The only way there isn't an issue is if the documentation says it's a stop button and it behaves and looks like a stop button. Or the documentation states it's a record button, and behaves and looks like a record button. All of those conditions need to be fulfilled not just one or two of them. An egg is an egg not a chicken thing. If the behaviour is by design then there is a bug in the design.
If there's anything labelled "gain" and really it's "Velocity Trim" then that's the issue right there regardless of documentation. I don't have Sonar in front of me to validate so I don't know whether this is the case or not.
