1 Mic +
2 Receiver
3 Receiver
4 Mic -

The microphone is driven symetric with 2.9V 1.35kOhm. Microphone sensivity should be -42db (V/Pa) The Receiver impedance should be 150Ohm typ, 32Ohm min.

Headsets

Since the microphone is connected to a symetric amplifier it is important to use a headset with symetric cabling.

This headsets should work, the marked headset has been tested without problems:

BIZ-2300 Mono Balanced 2303-825-109
BIZ-2300 Duo Balanced 2309-825-109 (*)
BIZ-2400 Mono Balanced 2486-825-109
BIZ-2300 Duo Balanced 24869-825-109

The cable should be 8800-00-25A, with modular 4P4C connector on one side and headset connector on the other side.
