To connect the PRO 7 iC to the NCS-C003 Headset Interface Box requires the NCS-003-HHS
Headset Adaptor Cable. The two PRO 7 iC 3.5 mm phone plugs connect to their respective

is connected to the adaptor cable jack with the RED band. Connect the Soft Touch PTT switch
or alternatively the optional NCS-F230 Hand Switch or NCS-F221 Footswitch to the ¼ inch
phone jack on the front panel of the NCS-C003.
Installation of Microphone Jumpers in the NCS-C250
Microphone jumpers must be installed in the NCS-C250 to match the pin outs of the NCS-C003
Headset Interface Box. The proper installation of the mic jumpers for use with the NCS-
C003 and
adaptor cable is shown below. After all jumpers are installed refer to the NCS-C250 Instruction
Manual and set the mic audio level for proper audio output.
