 160cps
(Green) this is
the local background AWAY
FROM
THE AREAS of
Interest because the unit is
seeing radiation from all
around it.
 120cps
(Yellow)
– this is
the background at AREA 1
this
displays the local
background so it is
significantly lower.

If the unit BG is set at the
160cps
– then the Audio
Threshold = 223cps so it will
NOT sound the audio when the 200cps source location is passed.
 200cps
(Red) - However if the unit is positioned at the 120cps point and then the REACQUIRE
BG selection is made, the Audio Threshold is then 175cps so the 200cps source will give an audio
response.
NOTE : Of course if the radiation source signal is quite large then such a small BG change has little affect,
so under most circumstances the REACQUIRE BG step is not required. However if you scan the
area and find NOTHING, using the REACQUIRE BG process defined above may make the source
easier to find.
