This.is.the.least.preferred.method.of.applying.a.signal.on.a.target.conductor.
because.it.can.easily.be.picked.up.by.other.non-target.conductors.in.the.area..
However,.it.is.the.preferred.method.of.applying.a.signal.to.multiple.cables/pipes.

4.. Turn.on.the.transmitter.by.pressing.the.frequency.key.
5.. Select.High.Output.level.for.the.best.signal-to-noise.ratio.
Note: If nothing is plugged into the output ja ck of the transmitter, the
transmitter will automa tically turn on the internal a ntennae, and 82 kHz
will broadcast in inducti on mode. For best results, the receiver should be
at least 40 feet (12 m) away from the transmitt er to begin tracing the target
path. Attempting to tra ce the target close to the transmitt er may lead to false
indications due to the receiver detec ting the large magnetic field r adiating
from the transmitter.
