“pick up” signals from electrical devices other than the FOX.
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 Indicator can’t differ-
entiate between these signals…… so if the user is observ-
ing just the Indicator, 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 Indicator is re-
sponding to is the target signal.
8.2.3: Sensitivity Control
The Sensitivity Control (FF) adjusts the loudness of the sound
from the Speaker. Usually, when initially searching for the
target signal, the Control is set to maximum. At this maxi-
mum setting, electronic noises from electrical wiring or de-
vices 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 Control setting can be reduced, which will reduce the
loudness of the other interfering sounds. Repeating this pro-
cess will lead the user in the direction of the wire with the
target signal on it.
Helpful Hint
The user can often track the FOX signal to its source without
adjusting the Sensitivity Control. When the target wire is in
a group of wires, adjusting the Control can help determine
