Senheiser PC3 Headset on a 6400M

Hi Folks

I have a 6400M and a Sennheiser PC3 headset.

I use it with all my transceivers (not the Flex). An adapter supplies the headset with 8V.

The 6400M has a separate microphone input. The original FHM-2 microphone has a 3-pin connector.

In the menu, I can enable the bias. I thought this would supply voltage to the microphone jack, allowing me to use a headset with an electret capsule. But it doesn't work.

Am I misunderstanding something?
