ecking the strength of wireless radio signals
The receiver has two lights that indicate the strength of
the received signals transmitted wirelessly over radio.
The Right light is for the Blue transmitter, and the left one
for the White transmitter. For strong radio signals, the
lights will be continuously on. The lights may flicker for
weak signals, for example, in the case of plastic pipes, or
when correlating leaks in metal pipes over long distances.
For very weak signals the lights will go off, however, you
may still be able to successfully correlate a leak even if
radio signal lights are off.
