TrueTrace .... a test technique which greatly improves the
accuracy of the trace. Shorting the target wires together
causes the cadence (the speed at which the tracer tone
warbles or pulses) of the tracer tone to change, positively
identifying the target wire(s).
Helpful Hint: If the suspect wires are longer than they need
to be, the user may not need to strip the wire to bare metal
in order to activate the TrueTrace feature. Select a pair of
suspect wires. While listening with a HOUND or a cordless
phone (see Cordless Interface), use a pair of wire cutters
(diagonal cutters usually work best) to slowly apply pres-
sure to the wires. The metal jaws of the cutters will bite
through the insulation of the wires as pressure is applied,
shorting out the wires and causing the cadence of the tone
to change. The pressure can then be released, or the ends of
the wires trimmed off.
When the FOX 2 is initially set to the TRACER TONE mode, it
may come on with either fast or slow cadence.
60Hz Noise and Pulse Tone:
Although the FOX 2 is not affected by 60Hz Noise, its typical
for the HOUND, HOUND 2, or other receivers to pickup and
amplify the noise. It usually sounds like a humming or buzz-
ing sound coming from the speaker of the receiver. The noise
is usually at its worst around fluorescent lights. The HOUND
2, and other receivers, have a signal strength indicator LED
that aids in finding the FOX tone in areas where the back-
ground acoustic noise level is so high that the speaker can-
not be heard. When the speaker cannot be heard, the HOUND
