Probably the most notable signal, a buzzing sound, comes
from fluorescent lights. Other sounds can often be heard
when the HOUND 3 is placed near a TV, computer, or other
electronic device. The Signal Strength LED can’t differenti-
ate between these signals…… so if the user is observing
just the LED, without being able to hear the speaker, he may
mistake an interfering signal for the target signal. This is
where the earphone is handy. By using the earphone, the
user can determine if the signal that the LED is responding
to is the target signal.
6.4: Volume / Sensitivity Thumbwheel (F)
The Volume / Sensitivity Thumbwheel controls the loudness
of the sound from the speaker. Usually, when initially search-
ing for the target signal, the thumbwheel is set to maximum.
At this maximum setting, electronic noises from electrical
wiring or devices may be heard. When the target signal is
heard, the user can track the signal to its source by moving
the HOUND 3 in the direction that makes the sound of the
target signal get louder. As the loudness of the target signal
increases, the thumbwheel setting can be reduced, which
will reduce the loudness of the other interfering sounds.
Repeating this process will lead the user in the direction of
the wire with the target signal on it.
Helpful Hint:
The user can often track the Tone signal to its source with-
out adjusting the Volume / Sensitivity thumbwheel. When
the target wire is in a group of wires, adjusting the
thumbwheel can help determine which wire is the target wire.
