2. Move left and right, if the red-light flashes and there is a sound prompt, it means there is an emission source. The more red signal lights, the stronger the signal.

3. Short press the sensitivity adjustment button. The more red lights, the higher the sensitivity, which can expand the search range.

4. Cyclically adjust the sensitivity button to reduce the number of red lights, lower the sensitivity, and reduce the detection range, so you can finally find the emission source.

5. You can also plug in Type-C headphones to use silent detection.

6.Short press the power button to switch gears. “Full-band” is full-band detection, frequency detection range (1MHz-6. 5GHz), and the detection method repeats steps 1-5.

B Strong Magnetic Detection

1.Short press the function button to turn on the device to detect strong magnetic field. At this time, the strong magnetic field detection of the device will be turned on, and the “strong magnetic field” indicator light will light up. If the target device is detected, the built-in buzzer will give a sound prompt.

2.Move left and right. If there is a sound prompt, it means there is a transmitter. The more red light signal indicators, the stronger the signal.

3.Short press the sensitivity adjustment button. The more red lights there are, the higher the sensitivity, which can expand the search range.

4.Cyclically adjust the sensitivity button to reduce the number of red lights, reduce the sensitivity, reduce the detection range, and finally find the emission source.

C Infrared Detection

Short press the function button to switch the device from RF detection mode to infrared detection mode. When the device is in the infrared detection mode, the red light on the top of the device is turned on, the infrared detection sensor on the front of the panel is in the receiving state, and the user holds the device to detect and scan the environment. When the infrared detector detects infrared rays in the environment that exceed the set intensity value, the device will issue a sound and light alarm prompt. At this time, the device’s strong magnetic detection will also be turned on at the same time. If the target device is detected, the built-in buzzer will Sound prompt.

D Short Press the Sensitivity Adjustment Button to Control the Flashing Speed of the Red Light.
