Rotary panel interruptible foldback (IFB) operation

When a rotary panel key is assigned as an IFB source, you can use the rotary control to adjust the audio level sent from the panel to the destination or the listen level at the panel.

If you latch the call to the IFB destination by momentarily pressing the talk button, you can adjust the level of the audio sent to the IFB destination by turning the rotary control.

If the call to the IFB destination is not latched (the talk button is held down) the audio level is adjusted by pressing and turning the rotary control.
