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

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.

No compensator –the actual balance of the sensor with the

compensator turned off.

Compensator on / off –– enable or disable the auto-

compensator.

USER PROFILE Menu Item - USER PROFILES

Save setting-record the current settings in the selected profile.

There are 8 profiles available. Factory reset-reset the device to

“initial basic” >> click CATERORALLY I DO NOT RECOMMEND,

it’s better to load an empty profile, there will be basic

settings. Load setting-restore previously saved settings from

the profile.

Menu item BACKLIGHT LEVEL - SCREEN BACKLIGHT LEVEL;

Backlight — Setting the brightness level of the backlight; 0 -

off ... 100 - the highest brightness. Change the value with the

buttons "Right" and "Left." “OK” - exit with saving the result,

“Esc” - exit without saving.

USER PWM Menu Item - THROUGH CURRENT ADJUSTMENT

User PWM – value (from 0 to 64) of the level of the user signal

of pulse width modulation PWM (PWM). In our case, this is

the sensor current control signal. In the top line, use the Up,

Down, or Left, or Right buttons to set the PWM level. The

bottom line displays the current value in the TX sensor coil.

Current is displayed in mA milliamperes.

>> I recommend setting 70-100mA, for different sensors

differently, the higher the value, the greater the influence of

soil on the device, that is, the device is more difficult to cope

with the response of the soil, if you wind too much current,

the device can see through the air a half meter -WOW , and 10

cm into the earth is sad, so that this does not happen, you

need to intelligently regulate the current in TX, for “weak”

soils you can 100, and higher, for example, in sandy soil, and

for chernozem 60-85 mA for large sensors , and for smaller

sensors, a little more is possible.

FILTER menu item - SOUND FILTER SETTING

Ground filter - Suppression of the effect of mineralization of

the soil allows you to reduce the effect of soil on the input of

the device, slightly increase the depth of the search, and also

helps to configure the detector for the best scanning speed by

the search coil of soil for optimal operation. A decrease in soil

filtration when searching on low-mineralized soil increases

the detection depth, however, on highly mineralized soil the

depth will be small. By adjusting the level of soil filtration, You

can optimize the search for local soil conditions, as well as the

scanning speed of the search coil of soil. Lower filters allow

slower scanning speeds by the soil coil. The choice of higher

levels of filtration gives the possibility of a higher scanning

speed by the search coil of soil. Quasar-AWP allows you to

select five combinations of digital filter configuration. It can

take the following values:

• Very slow - very slow

• Slow-slow

• Normal — normal

• Fast — fast

• Very Fast — very fast

Change the value with the buttons "Right" and "Left." “OK” -

exit with saving the result, “Esc” - exit without saving.

Menu item MAIN SCREEN –– SCREEN VIEW

Signograph + VDI - display of the VDI scale consisting of 16

segments, the top row - the segments of the scale, the bottom

row on the left: VDI value, the bar of the response level from

the target, bottom right - alternating values: current in the

sensor in mA, ground balance, and battery voltage in V.

Signograph is the same as the previous menu item, only

without VDI value VDI is the display of the value of the VDI

number in large digits, the signal level is on the top line above

the current values in the sensor, the level of ground balance

and the supply voltage.

LAG SIGNOGRAPH submenu item - DELAY OF SIGNOGRAPH

INDICATIONS

• Value from 0 to 31. Delay of the indication of the

signalograph allows you to better control the location of the

target in the segment of the VDI scale during posting.

Convenient working value of 20-25.

MASK menu item - HIDDEN MASK OF SECTORS

Set Mask-Allows you to enable / disable any of the 16 sectors

in the VDI range. The top line displays the current mask, the

bottom line shows the cursor, which can be moved with the

"Left" and "Right" keys. Any of the Up or Down keys, the

current sector is enabled or disabled. To memorize the mask,

you must press the "OK" button, when exiting by "Esc",

changes are not remembered. "Checkers" displays a sector

that will not be voiced.

SPEED OF GEB - GROUND ADJUSTMENT SPEED

Autotrack speed-speed adjustment for changes in soil. Allows

you to adjust the speed of auto-tuning "under the ground" in

the search process or disable auto-tuning. The more difficult

the soil (salt marsh, clay), or the more often you switch from

denser and drier soil (such as an old pasture) to loosened soil

(plowing) - the faster the adjustment. It can take the following

values:

• “OFF” - disabled

• “SLOW” -slow

• "MEDIUM" - average value

• "FAST" –fast

To memorize a value, it is necessary to press the “OK” button;

when exiting via “Esc”, changes are not remembered.
