Operating Notes
1.
If, while searching, random disturbances or prolonged changes
of the frequency of the sound signal (false signals) appear, the
“RETUNE”
button must be pressed. This action can be repeated
several times to ensure complete elimination of the interference
and re-establish stabile operation. Reducing the sensitivity and/or
excluding the additional signal amplification
“BOOST”
will also
reduce interferences.
2.
To maximize the sensitivity and the stability of the device during
operation, it is advisable to press the
“RETUNE”
button every 30-
90 seconds.
3.
When switching
“Off”
the detector, the red LED
“Battery!”
will
be lit for a second or two. This does not indicate a battery
problem. Only when this LED lights-up when the detector is
turned “On”
(running), you should charge the battery.
4.
Keep a consistent height of the coil above the surface during
the search to ensure optimal functioning of the systems to
eliminate the influence of the ground and the maximize detection
depth.
5.
Do not use (or leave) the detector in a humid environment or in
wet bushes, snow and/or water – the electronics unit could be
damaged as it is not sealed. When you connect the coil to the
electronics, you should prevent the entry of dirt or moisture in and
around the contact pins of the connectors.
6.
Working with the detector in industrial areas and places with a
large amount of metal junk in the soil, and/or with presence of
industrial electromagnetic interferences, can lead to instability
and/or inability to work. This requires reducing the sensitivity of
