3. The signal from the communication, to which
the route locating transmitter is directly connected,
is conventionally named - «friend». The «parasitic»
signal from the nearest communication, on which
the generator signal is transferred, in conventionally
named as «somebody else’s».
4. Based on the direction of the
«arrow» it is possible to distinct
«friend» signal from «foe» one, since
the current direction in «friend»
communication is opposite the
«transferred» currents flowing
through «foe» communications.
5. «Signal direction - forward» is the conventional concept and «assigned» by the operator
for this position of the sensor relative to the this route. The «assignment» is performed by
the pressing of the button « », when the sensor is located exactly over the «allocated»
communication, that is supposed to be «friend». After that, the pointer of the signal direction
takes the form - 1.
When switching to the «foe» communication with the other «signal direction» (or at the change
of the sensor position to the «reverse») the sound will be emitted (if switched on) and the arrow
will show the «signal direction - back 1».
