The Series 4000 Telephone Radio Headset Interface (TRHI) (Part # 950-9439) is a headset
interface used as a radio control console and as a telephone instrument. It should not be
confused with the headset jackbox, which provides a jack for a console. The TRHI is low
profile and is mounted under the writing surface of an operator’s station. It is equipped
with a dual-prong jack (accepting either 4-wire or 6-wire plugs) and two controls to adjust
the volume of the radio and telephone separately. With the proper signals available from
the telephone instrument, the following operation will occur:
