Note: When tracing a cable run from the tone generator to the end of the cable, applying the tone
on a single pin will allow the tone to be detected at a greater distance from the cable. When trying
to locate a cable in an equipment room or patch panel, sending the tone through all 8 pins or a
single pair will limit the tone signal from spreading to other nearby cables. The tone will be loudest
when the probe tip is placed directly on the wires the tone is being sent through at the end of the
cable. When sending a tone through a single pair, verification can be made by shorting the suspected
pair. The tone will be very faint when the pair the tone is being sent through is shorted.
