HUNTER PRO

To do this, move away from the window as far into the room as possible and if the signal level drops noticeably, then return to the window and press the encoder 1, evaluate the signal power level displayed on the display. If the device determines the signal strength in the range of -50dBm — -40dBm in the line of sight to the base station, then most likely it is a signal from the base station. As a rule, the signal received from the base station in the line of sight of 200-300 meters does not exceed the level of -35 dBm.

To use the Hunter-PRO device for the first time, follow these steps: 1. Turn on the device by pressing the power button. 2. Go to the OPTIONS menu to adjust the basic parameters of the device according to your requirements. 3. Select the signal attenuation level (attenuator) if necessary. 4. Switch to the "SEARCH" or "GUARD" mode, depending on your task.

The "SEARCH" mode is designed for active search and localization of signal sources by moving the device through space. It includes functions for listening to radio frequency signals and selecting ranges. The "GUARD" mode is used for passive monitoring and records registered alarms when the device detects suspicious signals in the set ranges.

Hunter-PRO is capable of detecting signals in various radio frequency ranges used for data transmission, listening and video surveillance. Specific frequency ranges can be configured via the "Range Selection" menu in the "SEARCH" mode.

The maximum detection range of the signal depends on the power of the transmitter of the listening device and the conditions of the environment in which the search is performed. Under normal conditions, the device is capable of detecting signals at a distance of up to several tens of meters.

To filter out false signals and background noise, you can use the built-in attenuator to adjust the level of input signal attenuation. This allows you to reduce the impact of non-dangerous sources and focus on searching for suspicious signals.

The results of the search and monitoring can be saved using the "GUARD" mode, which automatically records the recorded alarms. You can also manually keep records using the instrument interface, which provides detailed information about detected signals.

If the device shows a signal, but its source cannot be localized, try the following steps:
1. Adjust the level of signal attenuation.
2. Move slowly and methodically around the room, watching for changes in signal strength.
3. Use the radio frequency signal listening function to understand the nature of the detected signal.
