This operating manual is to get you acquainted with the construction, rules of operation
(intended usage, technical maintenance, repair process, storage) of bug detector
BugHunter Professional BH-03 Expert (hereafter referred to as the Product).
The product is a device, intended to detect near eld radio transmitters such as wireless
“bugs”, wireless microphones, wireless spy cams, portable radio sets, working cellphones,
cellular signal killers and suppressors, etc.

Anti-spy bug detector BugHunter Professional BH-03 Expert
Main advantages of BugHunter Professional BH-03 Expert over
similar devices:
1. The declared and real characteristics of the device are in strict conformity.
2. It covers the entire range of wireless“bugs”working frequencies (from 10 to 3500
MHz).
3. High sensitivity (throughout all the frequencies of the claimed frequency range).
4. Extended dynamic range.
5. It detects both analog and digital wireless bugs (that work on the principle of fast
pulses).
6. Automatic adjustment to background radiation levels.
7. OLED-display to provide the visualization of both the received signal type and the
frequency of periodic signal (or the identied data transmission protocol).
8. Switchable lters that exclude frequency ranges of base cellular communication
stations (GSM900/1800, 3G, 4G, CDMA450), and Wi-Fi (provides successful“bug”hunting
in modern city environment, highly contaminated by radio interference).
9. Vibroindication (switchable) and the possibility to connect the earphones to get the
implicit warnings of wireless "bugs".
10. Operating in dierent modes (sound indication, sound feedback, mute).
11. The possibility to use rechargeable batteries or built-in charger.
12. Search and security operating modes.
13. An additional extendable antenna (to increase the sensitivity).
14. Low battery indicator.
15. Self-diagnosis.

1. Specication and operation
1.1 Application area
1.1.1 This device allows users to monitor the signal strength ranging from 10 to 3500
MHz and can also be used to detect transmitting devices, such as“bugs”, wireless
microphones, wireless spy cams, portable radio sets, working cellphones, cellular signal
killers and suppressors, etc., within the area nearby.
1.1.2 Device software provides:
- specially designed algorithm of measuring the digital and analog signal strength and
displaying its average and peak values on the time curve;- displaying of the periodic
signal frequency (or the identied data transmission protocol);
- sensitivity adjustment (selection of the sensing element’s output characteristics for
providing the most convenient detection of local signal peak);
- possibility to work in“security”mode (which includes the adaptation to the ambient
background, switching to the standby mode and further exit from the standby mode after
when signal sources have been detected, accompanied with sound, visual and vibro
indicating);
- displaying of the time based diagram of radio environment;
- minimized impact of the isolated signal sources (such as base cellular communication
stations, Wi-Fi access points) on the process of radio transmitting equipment detecting;
- sound indication of the receiving signal’s level;
- vibroindication of exceeding the preset threshold by the average signal (with the
vibration intensity control);
- current time indication;
- battery charge level indication.

1.4.2 Picture 3 illustrates the display in the“search mode”.
During the measurement process, the average (item 1) and peak (item 2) values of the
received signal strength are being constantly displayed on the screen.The displaying is
performed in logarithmic representation, on a selected sensitivity range scale, and as a
graph of values for the last 5 seconds. Also the value (in MHz) of the set periodic signal or
the identication of the data transmission protocol are displayed (item 3), selected
sensitivity level (item 4), vibroindication engagement threshold (item 6) on a scale of a
current level of a received signal’s strength (item 5) are also displayed on the screen.
At the same time the device displays on the screen the lter state (switched on/o, item
7), vibroindication state (switched on/o, item 8), adjusted sound mode (mute, sound
indication or feedback, item 9), current operating mode (“search”or“security”, item 10),
and the selected type of power supply (item 11).
