C003 Headset Interface Box
To connect the Pro Set Elite iC to the NCS-C003 Headset Interface Box requires the NCS-003-
HHS-0.7 Headset Adaptor Cable. The two Pro Set Elite iC 3.5 mm phone plugs connect to their
respective jacks on the Headset Adaptor Cable. Make sure that the color of the plug and jack
match. The optional NCS-F230 Hand Switch is connected directly to the ¼ inch phone jack on
the front 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.
The Sel Audio and Unsel Audio jumpers can be swapped to reverse the audio in the headset
earpieces.

Mechanical Adjustments
The microphone boom has a steel rod inside that can be easily bent to place the microphone
holder in the desired position.
Microphone Element
The Heil PRO SET Elite iC
is equipped with an electret microphone element. This element has
a wide frequency response for full voice range articulation. The element is optimized with an
increased output of +6 dB at 2000 Hz (middle of the human voice pattern).
Pro Set Elite iC Termination
Microphone Audio
The microphone audio cable for the PRO-SET Elite iC is terminated with a 3.5 mm mono
phone plug. A RED band around the plug housing identifies this phone plug.
Earpiece Audio
The earpiece audio cable is terminated with a 3.5 mm stereo phone plug.
Speaker Phase Reversal Switch
The Phase Reversal Switch allows the operator to acoustically “move” the signal being
monitored just by reversing the phase switch. This feature is best used when monitoring
multiple signals as in HF operation. In one position the signals appear to be centered between
the two speakers while the other position creates a spatially widening sound field that appears
to “spread” multiple signals making the desired signal easier to copy.
