DC10 Intercom Problem?

[falcon10]

Anyone familiar with the DC10 cockpit intercom system? When I attempt to plug in my headset into the mic jack located on the sidewall where the O2 mask plugs in, I get a hot mic and the PTT on the control column has no control over the headset mic.

At this time, I am unable to use the boom mic on my headset because of this issue.

Thanks!

What make of headset?

Does it behave this way at the other (F/O, F/E, jumpseat) stations?

If memory serves, though it probably doesn't, that is the wrong jack for a headset mic, it is wired differently, and a headset boom mic needs to be connected to the mic jack on the jack panel, that's where you plug in your headset.
