"External Mic Only" option

[werdnuts]

Hey gang. I've been playing with my new 5k and CPS 12. I was wondering if there was a similar option to the MTS2000s -- the "External Mic Only" options. This is the option that when a RSM is used, the PTT on the radio activates the Mic on the RSM rather than the radio's internal mic.

Any thoughts?

If you have a commander series mic there is an option to lock the radio to the RSM's controls.
