Sensitivity Setting; Electromagnetic Interference - Kayoba 002163 Operating Instructions Manual

EN
METAL mode. See section on ground balancing
and precise localisation (stationary mode).
Target reading does not work in ALL METAL
mode. Switch to a motion mode to show target
reading and depth.
NOTCH
Use NOTCH mode to selectively eliminate
one or more metals from the categories.
The DISC/NOTCH reading shows the current
discrimination level and the probable character
of the detected object is shown by the arrows
on the top of the display. SENSITIVITY indicates
the current sensitivity level. The depth reading
indicates the probable depth of the target.
Setting the area for NOTCH mode
In NOTCH mode, press ADJUST to go to area
setting for DISC/NOTCH mode. DISC/NOTCH
appears at the bottom right corner of the
display. Press the up or down arrow until the
arrow for the desired category flashes in the
target indication. Press ENTER to eliminate
the corresponding category. Repeat if several
categories are to be eliminated.
AUTO-NOTCH
When this mode is activated AUTO-NOTCH is
shown at the bottom of the display and scrap
metals are eliminated automatically so that
only coin detection is active. Metals such as
different types of caps, iron, foil and can rings
are eliminated. The range for DISC/NOTCH
(not adjustable) shows the current target
identification area and the probable character
of the detected object is shown by the arrows
on the top of the display. SENSITIVITY indicates
the current sensitivity level. The depth reading
indicates the probable depth of the target.

SENSITIVITY SETTING

The sensitivity setting in DISC, NOTCH and
50
AUTO-NOTCH mode
Press ADJUST to go to sensitivity setting. The
display shows SENSITIVITY down to the right.
Press the up arrow to increase the sensitivity or
the down arrow to reduce.
NOTE:
The sensitivity cannot be adjusted in ALL
METAL mode.

ELECTROMAGNETIC INTERFERENCE

The sensitivity setting is intended to eliminate
electromagnetic interference. The metal
detector is very sensitive. The search coil creates
a magnetic field and functions as an antenna.
If the machine emits irregular audio signals
when the search coil is held still the machine
is probably detecting another electromagnetic
field. Common sources of electromagnetic
interference are power lines (both overhead
and buried), motors and electrical appliances
such as computers and microwave ovens.
Some electrical appliances, such as dimmers
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.
