ideal for use with a variety of frequency generators, radionic machines and other energy devices. Wires not included but easily connects to most instruments with standard banana plug wires (such as the red wires included with the GB-4000). Includes instructions for standard connection set-ups. Only one positive (red) wire connection is required with the GB-4000 since most frequency imprinting procedures use RF (Radio Frequency) mode and the PWM 060 Imprinting Plate is acting as a broadcast antenna.
