Abstract
Circuit ends of a cancel loop circuit and a frequency generator circuit are connected with circuit lands in such a manner that the two circuits are not allowed to electrically communicate with each other. The cancel loop circuit and the frequency generator circuit are subjected to an electrical conductivity test to detect any short circuit therebetween. After successful testing, the lands located adjacent each other at one side of the circuits are connected with each other, thereby electrically communicating the cancel loop circuit and the frequency generator circuit to obtain a completed coil circuit.
