+These options are to control (and therefore are only applicable to) the high cluster character display. (While this documentation only covers BMBT usage, I suspect they would apply to MID.)

 ## Use Cases
 
-### Service Mode
-
-### Weather Band
+These use cases became obsolete with the introduction of NG radios which used the digital radio layout for all sources. This is in order to support split screen which is dependent on the digital radio layout.
