TC70 Data Wedge Demo

My Data Wedge Demo app is not working.

 

It starts up, but when I press the top button on the left side, nothing happens.  The lower left button does nothing either.  I have compared the settings with my other TC70 which works fine and cannot figure out the problem.

 

Also, on the screen there is a round yellow circle with a barcode in it.

 

How do I get rid of that?
