Some of you people act as if it's unreasonable to expect you to spend 2 minutes reading all the posts in this thread, where every question you have has been answered.
You don't "start up" Sentinel in a mode for any radio. The profile you last used is what determines what radio type is used. The reason it asks you when you start the program for the first time is because you've never told it before, and it needs to know so it can write the profile for the first time.
You set the target model from the Tools menu on the main page of Sentinel, not in the Miscellaneous section of a random profile. The display editor is accessed from the Edit menu on the main page of Sentinel, when the target model is set to SDS100.
All of this is either posted in this thread or intuitively obvious if you spend 90 seconds thinking about it.
