then hold the receiver to find the target line. when the probe
is close to the target cable among plenty of cables, you will
hear “beep, beep”, and the voice is the loudest, the signal
light would be brightest. (Sometimes there may be some
noise, it is difficult to distinguish which one is the goal, here
you can turn down the voice to the best status.)
