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.
