It is best to only turn the detector on
when outdoors and away from sources
of electromagnetic disturbance such
as power lines, transmitters, electric
fences and phone towers. These
sources may cause the detector to
perform erratically, giving numerous
false signals.
If the detector emits an overload
sound, move the coil away from any
large metal objects. Overloading is
not harmful to the electronics of the
detector.
The On / Off button is located
on the back control panel.
To turn the detector on or off:
Press and release On / Off.
Many of the GPX-4000
functions are accessed
through the LCD Menu.
These are explained in
further detail throughout
the rest of this manual.
(pg. 46, 47)
Until you become more
familiar with the GPX-
4000, the detector can
simply be operated with
the Factory Presets and
the front panel controls.

time before turning the detector on again.
