battery is fully charged, you will hear 6 or 7 beeps. When you hear only 1
or 2 beeps, it will be time to replace your battery. This test can be per-
formed at any time while the detector is turned on.
Adjust THRESHOLD
To adjust the threshold tone, turn the THRESHOLD knob clockwise
until you hear a slight but steady tone. You will have to turn the knob to
somewhere between the 1 o’clock and 3 o’clock position to get the best
hum.
The purpose of the threshold tone is to give a reference to judge targets
for pinpointing and to adjust the ground balance. (For more information on
ground balancing, see the “Adjust GROUND BALANCE for Air Test”
section below and the “Ground Balancing in the Field” section.)
In the field, some targets may be small enough or deep enough that
they will not be able to generate an audio signal by themselves. By moni-
toring a threshold, you already have an audio signal so changes in volume
will be easier to hear. However, if the threshold is set too soft or too loud,
small changes in the signal will be hard to hear. Take some time and find a
threshold level that is right for you.
