Electronic unit:
1 - LCD display.
2 - Turn on / off the device.
3 - “OK” button, enter button for the soil balance menu.
4 - “Left” button, backlight on / off button.
5 - Button.
6 - “Right” button, pinpoint call button.
7 - “Cancel” button and button to enter the device menu.
8 - Up button.
Instrument screen in main mode:

Switching on the device – briefly pressing the button on / off
the device. Turn off the device - press the on / off button of
the device.
The “*” symbol is displayed when the backlight is on, it is not
recommended to search with the backlight on during daylight
hours, this significantly increases power consumption.
8.0 V in this case, this is a supply voltage of –8.4 V equal
to the full charge of the batteries; at a voltage of 6.0 V, the
device will begin to signal a discharge. The value of the
supply voltage is alternately replaced by the value of the
soil balance in the format "0.0", and the value of the
current value in the TX in the format "00 mA", the value of
the supply voltage is displayed in the format "0.0V"
In the operating mode, the Up / Down buttons can be used to
quickly change the Barrier value — the higher the value, the
less false alarms, with the help of a barrier it is possible to
reduce the parasitic effect of noise on the operation of the
device, to achieve comfortable operation. The value can be in
the range from 1 to 32. Barrier - smooth adjustment, it is not
necessary to ascribe the emurol of the depth regulator, but
there is no abuse of the increase in the barrier, the device may
lose a few centimeters in depth.

Pinpoint - called by pressing the "right" button. Static search
mode - designed to more accurately localize the target. Exit -
pressing any key. To set the initial state of sensitivity of the
pinpoint, press the "Left" button, using the "Up / Down"
buttons the sensitivity of the pinpoint is adjusted.
Soil balance –called by pressing the “OK” button. For correct
readings, enter this menu with the sensor raised above the
ground. The top line displays the response from the ground in
graphical form, with 0 in the middle. In the bottom line is the
value of the current angle of the soil response in degrees. The
manual angle can be changed using the "Left" and "Right"
buttons, the step is 0.1 degrees. Raising and lowering the
sensor should achieve minimal deviations on the upper scale.
For the changes to take effect, you need to click "OK", if you
exit by pressing Esc, the changes are not remembered. When
you press any of the Up or Down buttons (from the balance
screen), the automatic ground adjustment mode starts. This
mode should be started with the sensor raised, after which
the user has about 4 seconds to lower and raise the sensor.
The angle of response of the soil will be calculated,
remembered, and the device will switch to the main mode.

The device menu is called up by pressing the \ esc Menu
button. Menu block diagram:
Audio Menu - AUDIO SETTINGS.
Volume-adjustment of the volume level. The range of volume
levels is 0-31. Operating values at the level of 5-10.
Volume variation Sets the sound level of the target,
depending on the level of response. The finer (or deeper) the
target - the quieter the sound of the target. The larger the
target or the less its depth, the louder the sound. The range of
change is 1-7. The buttons "Left" and "Right" - decrease and
increase the range of volume changes, "OK" - memorization,
"Esc" - exit without storing. I recommend setting the value to
2-3.
Sound freq max-maximum frequency (pitch) of sound — the
higher the frequency, the more “squeaky” the instrument, I
recommend trying different values and choosing the most
comfortable one for your ears

Sound scheme-options for scoring goals.
Scheme 1: Frequency smoothly varies depending on the VDI of
the target over the entire range.
Scheme 2: Frequency varies smoothly depending on the VDI
from 90 to 131 degrees. Goals below 90 are voiced in low
tone, above 41 in high tone.
Scheme 3: Goals below 90 are voiced in low tone, above 90 in
high tone.
Threshold Thrashhold. Background sound in the absence of a
target under the sensor, voiceover of clean soil, Off - off, 1 ....
32 - volume of the trashhold.
LF boost-control of suppression / gain of volume in the field of
low frequencies. 5 options are available:
• suppression -6 dB per octave
• suppression -3 dB per octave
• 0 - no adjustment
• rise 3 dB per octave
• rise 6 dB per octave

FM Transmitter - a wireless FM signal transmitter, you can use
wireless headphones with an FM receiver, or connect wired
headphones to your phone / player, turn on the FM receiver
on them, and hide the device somewhere in the inside pocket
to search comfortably, because between the device and the
search engine do not “hang” any extra wires. The signal
transmission range is up to 5 meters
• FM ON \ OFF –– turn the transmitter on and off.
ATTENTION!!! When the transmitter is on, sound is not output
to the device’s speaker and can only be heard through the
receiver.
• FM frequency – transmitter frequency. It is in the standard
range of 70.0 MHz –108.0 MHz. It is necessary to choose a free
frequency so as not to listen to coin signals on the chanson fm
wave
It should also be noted that if the search is carried out
next to a similar device at the same transmitter frequency,
then at a distance of 3-5 meters You will listen to each other's
signals, you need to use different signal transmission
frequencies.
Menu item HW OPTIONS - HARDWARE SETTINGS.
TX frequency - (TX transmit loop frequency). Allows you to set
the frequency of the device within 4-20kHz. The mode is
needed not only to set the frequency of the TX, but also to
tune the TX circuit to resonance. In manual mode, the
frequency is changed using the "Left" and "Right" buttons,

while the current consumption of the TX output stage (in mA)
is also displayed on the screen. When you press any of the Up
or Down buttons, the device switches to the mode of
automatic selection of the resonant frequency according to
the maximum current of the output stage. To save this setting,
click the “OK” button. When exiting “Esc”, the setting is not
remembered.
Voltmeter - correction of the battery level indication. The
voltmeter value is changed using the "Right" and "Left"
buttons. “OK” - exit with saving the result, “Esc” - exit without
saving.
U min — Sets the threshold for the low battery warning. The
value is changed using the "Right" and "Left" buttons. “OK” -
exit with saving the result, “Esc” - exit without saving. When
powered by two Li-ION batteries connected in series, set the
value to 6.0V
Ferrite calibr ferrite calibration. Allows you to set the initial
value (ZERO) of the VDI scale. Take the angle of response from
ferrite as 0 degrees (if in very simple words, it allows the
device to understand where copper is, where ferrous metal,
etc.). Manual mode is possible, in which the “Left” and “Right”
buttons set the angle of rotation (delay) in degrees. In this
case, the response level is displayed in the upper line, moving
a piece of ferrite over the coil, and changing the angle of
rotation, it is necessary to achieve a minimum deviations of
the level indicator from 0. By pressing any of the Up or Down
buttons, the device switches to the automatic ferrite

calibration mode, while the user has about 4 seconds to spend
a few times a piece of ferrite over the coil. A small piece of
ferrite should be used, and do not bring it close to the sensor.
The angle of response from it will be calculated, but to save
this setting, you must click the OK button. When exiting “Esc”,
the setting is not remembered.
>> For RK instruments, the value is usually in the range from -
20 to -45. Also, after automatic calibration, I strongly
recommend manual calibration so that there is no response to
ferrite, the average size of a copper coin was about 80-81
according to VDI, a piece of foil 1.5x1.5 cm (not a lump) was
about 0 by VDI, and 5 kopecks of the USSR about 50 by VDI.
Remember - the correct ferrite setting is the key to the correct
operation of the device. Values need to be adjusted manually
+ \ - a few points, for example, auto-tuning set the value to -
30, save the settings, exit the operating mode, wave the
ferrite - there is a weak response, wave the copper coin, for
example, the value for VDI is +85, we return to the settings
and reduce the value to -29, save and exit to operating mode,
wave with ferrite - it is not voiced, the copper coin became
valid +83 by VDI, return to the ferrite calibration menu and set
the value to -28, save, exit, wave copper coin - the result is 80-
81, and then 5 kopecks of the USSR, foil, etc., in general,
ferrite calibration is a matter of experience, if the ferrite is not
set correctly, the device may not see large copper targets at a
depth, giving false positives for strikes and show other
negative phenomena. Understanding this setting is the key to
a comfortable and productive search.

COIL BALANCE menu item - SENSOR BALANCE
In each subparagraph, the projection of the unbalance vector
X (top line) and Y (bottom line) is displayed in graphical form,
as well as the unbalance range in millivolts (top line) and the
angle of the unbalance vector in degrees (bottom line) in
numerical form. The screens of all 3 points are identical, and
differ in the letter in the second line:
• "B" - "Balance"
• "D" - "Desired balance"
• "N" - "No compensator"
Desired balance – value of the desired sensor balance level.
The amplitude and phase value are set to which the auto-
compensator needs to balance the sensor. Use the Up, Down
and Right, Left buttons to achieve the desired amplitude and
phase value.
For RC devices in Desiredbalance, you need to set the
following values: Do not ask why, just put 100-150 mV and
about -160, both vectors should be to the left, as in the photo
above
.
For other users, I recommend consulting the
manufacturer of your device.
