I found a little bug in User Interface, affecting models with defined pre-flight stick or switch settings.
For next step it is assumed that at least one stick or switch is not in pre-flight state for the model to be selected.
In normal case, if I will turn on the DC16 by power button and then press "yes" for activation the display will show an explaining picture of the transmitter with the mismatching stick or switch blinking. At top of this image there is a message "Check Stick and Switch Positions".
Same happens if I will manually select another model via menu while the DC16 is already running.
The bug occurs, if I will turn on the DC16 by power button and then immediately select a new model instead of just pressing "yes" for activation. In this case the explaining picture of the transmitter will not show up, just the message "Check Stick and Switch Positions" will be visible. Therefore it is sometimes difficult to find out which stick or switch is not in pre-flight state.
First image shows bug case, second normal case.
