Surface Elimination - Kayoba 002-163 Operating Instructions Manual

for household lighting, produce powerful
electromagnetic interference and can cause
the machine to emit irregular audio signals.
Other metal detectors can also generate
electromagnetic fields. Keep at least 6 m away
from other metal detectors when in use.
DIFFICULT GROUND CONDITIONS
The sensitivity setting can also be used to
reduce the number of false signals in difficult
ground conditions. The machine has a
special circuit to reduce interference from
minerals in the ground, but this function
cannot completely eliminate the risk of false
signals. Strong magnetic fields in the ground,
which can occur in rocky terrain, can cause
the machine to give readings even though
there are no metal objects in the vicinity.
Soil containing abundant salt and sand can
sometimes produce false signals. Set a lower
sensitivity if the machine emits false, non-
repeating signals.
SEVERAL TARGETS
If you suspect that there can be deeper targets
under a more superficial target you can reduce
the sensitivity to eliminate the detection of the
deeper targets. This makes it easier to localise
and identify the more superficial target.

SURFACE ELIMINATION

Press SURF ELIM to activate/deactivate surface
elimination. Surface elimination can only be
used in motion mode. Surface elimination
can improve the precision of the detector in
ground with large amounts of scrap metal. The
function eliminates signals from scrap metal
in the surface layer and balances the signals
from large target objects. The sensitivity of the
machine is reduced in this mode.
EARPHONE JACK
Earphones (sold separately) make it easier to
identify subtle signal variations, which makes
detection more precise. They also prolong the
battery life. There is a jack for stereo earphones
on the control panel.
NOTE:
• Reduce to low volume before starting to
listen to avoid hearing impairment.
• Prolonged exposure to high volume can
cause a permanent hearing impairment.
Audio Target Identification (ATI)
The identification of buried objects, which is
shown on the display, is very precise, but in
the field the user does not always have the
opportunity to look at the display. For this
reason buried objects are indicated by audio
signals. The audio signal system tells the
user that there is a metal object and also the
character of the object. This information can
then be confirmed on the display. The audio
identification system has three tone levels and
only works in motion mode. The machine must
be in DISC, NOTCH or AUTO-NOTCH mode.
• In ALL METAL mode the machine only
emits a monotone sound.
• Three different audio signals can be given,
depending on the character of the
detected object.
