I don’t see DSMX 2048 listed under Radio Types in the M-Series App.

If you only see DSM2 1024 and Mōvi Controller when you scroll through the radio types, you may be using the wrong set of arrows.

There are two sets of adjustment buttons (appearance will vary depending on your platform, Windows/Mac/Android). One set of arrows is the fine adjustment, one is the course. Try using the fine adjustment (or single arrow) and you should find DSMX 2048.

Always be sure to Write the settings from the System Menu so that they are retained on the next power up.
