mode
button PUSH:
The
button
PUSH
has
two
positions: 1 when the button is up
(ALL METAL position), then the
metals are not discriminated and
the detector reacts with a deep
toned signal. 2. the second position
is when the button is pushed (on
position DISC), then the detector is
in mode that discriminates the
metals. So when it detects a non –
ferrous metal, produces a solid
sound signal and when detects a
ferrous
metal
you
hear
an
interrupted sound signal. Besides
that the detector is supplied with a
pointer system, which is another
way to discriminate the metals. The
system has a middle point and
when you detect a ferrous metal
the pinter goes left – FERROUS,
and when you detect a non ferrous
metal goes right – NONFERROUS.

and you will hear loud and
uninterrupted sound. 5. Start
turning left slowly the TUNE knob
