Surface Elimination; Earphone Jack - Kayoba 002163 Operating Instructions Manual

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.

4. LOW TONE LEVEL
5. MEDIUM HIGH TONE LEVEL
6. HIGH TONE LEVEL
Low tone level
Caps, 5-cent coins and the smallest gold
objects generate low tones (low frequency
signal).
Medium high tone level
Can rings, screw caps, zinc coins, newer penny
coins (after 1982) and gold objects generate
medium high tones (medium frequency signal).
High tone level
Coins with the values 1 cent (1950), 10 cent,
25 cent and 50 cent fall in this category (high
frequency signal).
USING IN THE FIELD
Reading the display
Target reading
The display shows the probable character
of the target metal and the probable
target depth. When a buried object has
been localised and identified the detector's
identification is repetitive and unchanging.
If the target identification is not repeated
