KNS81 Ident?

[MiRexer]

Is there any way to monitor the audio identifier on the receiver in the KNS81? I thought maybe DME (or COM3) but that didn't seem to work. Digging in to the KNS81 (had one in a panel on a rental plane once but it was a mystery lol)

Apologize in advance if I missed it in the manual - I looked REALLY hard

Tertiary-clicking the volume knob should activate the ident for the RNAV, unless there is some funny business that's interfering with it.

I clicked that - but there's nothing on the audio panel for another nav - something has to be selected on the audio panel too doesn't it?
