detected, and when set to maximum (90) only
the most conductive items (Silver and Copper)
will be found. All other targets will be ignored.
For normal detector use it is not recommended
to search with the Discrimination set too high as
many desirable targets may be missed. Items
such as gold rings are not as conductive as a
piece of copper so will be ignored by the
detector if the Discrimination level is set too
high.
Sensitivity
The Sensitivity level alters how responsive the
detector is to signals received from the search
head. The higher the Sensitivity level, the more
responsive the detector. For general use it is
recommended that the Sensitivity level is set to
maximum (90), as this improves the detectors
ability to locate small or deep objects. In some
environmental conditions, the detector may
produce false beeps which do not indicate a
target. In this case is is recommended that the
sensitivity setting is reduced until the problem is
resolved.
Ground
The VK40 provides 2 different Ground settings
for detecting in different conditions. The two
settings are Inland and Beach. As wet sand has
a different effect on the detector to soil, when the
detector is used on the beach the Ground setting
must be set to Beach.
Menu Operation
To adjust each of the settings described above,
a simple menu system is used. The
MENU
key
on the keypad is used to select which setting is
to be adjusted, and the
▼
and
▲
keys are used
to alter the value.
With the detector switched on and operating,
press
MENU
to enter the menu mode. This will
cause the display to show the Discrimination and
Sensitivity settings, and the current setting of the
Sensitivity setting will flash:
While the Sensitivity value is flashing, pressing
the
▼
or
▲
keys will decrement or increment the
value, in steps of 5, respectively. Please note
that the Sensitivity and Discrimination values are
only adjustable in the range 0-90. Therefore
pressing
▼
when the value reads 0, and similar-
ly pressing
▲
when the value reads 90, will have
no effect.
To resume detecting, press the
P
key and the
detector will exit the menu mode. Alternatively, if
no key is pressed for a few seconds then the
detector will automatically return to its normal
operating mode.
Whilst in the menu mode, pressing
MENU
again
allows the Discrimination setting to be adjusted
in the same way as that described above for the
Sensitivity setting.
A third press of the
MENU
button changes the
display again:
Pressing either the
▼
or
▲
keys toggles the
detector between Inland and Beach modes.
Finally, after a fourth press of the
MENU
button
the
▼
and
▲
keys can be used to toggle the Auto
Power
Off
feature
On
or
Off
