1.4 Construction and operating
1.4.1 The Product is a portable device with a self-contained power supply. Picture 2 illustrates the
Product’s internal design and the scheme of its main parts.
Pic. 2 –Main parts scheme
The Product consists of an ABS plastic case with pre-installed circuit modules covered with a
protective and decorative film. The faceplate of the Product is made as keyboard with buttons and LEDs.
There are the following controls and indicators on the faceplate:
- ON/OFF - item 1;
- power indicator - item 2;
- mode selection button - item 3;
- mode indicator - item 4;
- sensitivity adjustment button - item 5;
- indicating scale of incoming signal level - item 6.
The Product is equipped with a battery compartment (item 7) with cover (item 8). The battery
compartment is covered by screws (item 9).
1.4.2 The device runs under a built-in microcontroller with pre-installed software. The Product
displays on the indicating scale the peak value of incoming radio signal strength according to the adjusted
range of sensitivity while operating.
1.4.3 The device is powered by a 3V lithium battery of CR2032 type. How to install the battery into
the case you can see in the Picture 2.
2 Correct use
2.1 Usage limitations.
2.1.1 Keep the battery compartment and the power contacts clean.
2.1.2 Change the discharged battery in time.
2.2 Pre-starting procedure.
To prepare the Product for working you should:
−loosen the screws and remove the battery compartment’s cover (item 8, Pic. 2), using a small
screwdriver, toothpick or other small, rigid object if needed;
−install the battery respecting polarity (Pic.3);
−place back the battery compartment’s cover and tighten the screws.

2.3 Operating.
2.3.1 Switching ON/OFF.
To switch the Product on press the button and keep it pressed for 2 seconds. When you do, the
Product will start self-diagnosing; while self-diagnosing sounds will be played and LEDs of indicating scale
will flash one at a time. After self-diagnosing the sensitivity of the Product will be adjusted automatically,
and the Product starts constantly measuring the electromagnetic field level.
The power indicator lights constantly, if the battery charge level is well, and it flashes on and off, if
the battery charge level is 50% and less.
To switch the Product off press the button and keep it pressed for 2 seconds (as well as
switching on).
2.3.2 Operating modes.
The Product operates in two modes - “search” mode and “search with sound feedback” mode. To
switch between modes press button. The power indicator lights constantly in the “search” mode and
flashes on and off while operating in the “search with sound feedback” mode.
2.3.3 Sensitivity adjustment.
To increase the sensitivity press button gradually. If you are pressing and keeping pressed (not
less than 2 sec) the button, the maximum level of sensitivity will be set.
To decrease the sensitivity press button gradually. If you are pressing and keeping pressed
(not less than 3 sec) the button, the sensitivity will be adjusted to the level of radio background.
2.3.4 Battery charge level control.
If the Product is switched off, briefly press the button, and the battery charge level will be
displayed on the indicating scale for a short time:
- the whole indicating scale is displayed –the battery charge level is 100%;
- no LEDs lights–the battery is almost completely discharged;
- 1 LED - 15% of maximum battery charge level, 2 LEDs - 30% of maximum battery charge level,
and every next lighting LED gives +15% to the actual battery charge level.
2.3.5 Practical recommendations on using the Product:
- Before starting the search, switch off all radio-emitting devices if possible (Wi-Fi, smartphones,
tablets, computers and other household and office equipment). It simplifies the search by eliminating the
excess noise, and makes it possible to use higher sensitivity while searching.
- Turn the device on. The device automatically adjusts the sensitivity level and starts displaying the
actual value of signal strength on the indicating scale when you turn it on.
- Begin to walk around a room, holding the device at the distance of 0,3 –0,5 meters from the
researched surface. If a maximum signal strength level is displayed on the indicating scale, decrease the
sensitivity by pressing button and get on with searching for “bugs”. Repeat these actions until the site,
where the evident maximum level of emission is, is located.
- Another search method: after automatic sensitivity adjustment you can decrease the sensitivity by
one-two levels. Then search the supposed “bugs” locations from a distance of at most 0,2 meters. If the
signal maximum appears, reduce the sensitivity further and search the location from the closer distance (5..
10 cm) to find the location of the signal source more accurately. This method is suitable for rooms with a
high ambient electromagnetic emission.
- Carefully inspect for the presence of wireless “bugs” the site, where the maximum emission
strength was found, the sensitivity level can be adjusted manually at that by pressing (increasing)
button and ( decreasing) button.
- The locations where eavesdropping devices and hidden cameras are usually placed are: cavities and

chinks in plinths and walls, behind radiators, remote places on wardrobes and curtain-rods, cavities of
suspended ceiling, ventilating shafts, furniture elements, household equipment, flowers, car dashboards and
seats, etc.
- Use the “search with sound feedback” mode if needed, especially if you search in remote places
where it’s difficult to control the indicating scale. If you hear the indicative whizz, it means a radio bug or
another transmitter is located close to you.
- If all or a part of LEDs flash on and off rapidly, it means a digital (impulse) transmitter may
operate; and, instead, If LEDs light constantly, an analog transmitter operates nearby.
3 Maintenance
The maintenance includes changing the battery if it’s out of service and keeping the surface clean
by removing the dirt if needed.
4 Troubleshooting
