In operation, the SCR-296A radar could only track one target at a time. Target assignments were made from the harbor HECP/HDCP command posts by telephone, citing the approximate range and azimuth of the target. The SCR-296A radar operators would then find the target and pass a more precise range and azimuth to the plotting room at the gun battery by phone. Two sets of operators were required, one for the range position and one for the azimuth position. The range and azimuth teams each had one operator tracking the target while the other read the values and passed the information to the plotting room. The radar operators would continue to track the target and update the plotting room as the range and azimuth changed.
