Power on/off:
Power on: Press and hold the power button for 3 seconds, hear a "beep" sound, then turn on the device. The 5 white lights in the middle will light up in sequence and then turn off in sequence
Shutdown: Press and hold for 3 seconds to shut down, and hear a "beep" sound to complete the shutdown

Full frequency detection mode:
Press the button and the blue light will turn on to enter the full frequency range detection. Signal detection will be carried out within the range of 100MHZ-2.7G. Press the power button to adjust the sensitivity in a loop. The more white lights are on, the higher the sensitivity, which can expand the search range. Adjust the sensitivity. The less white lights are on, the lower the sensitivity, narrowing the detection range, and finding the emission source. The top red light is the strongest signal light, and there will be a "beep beep" sound when sensing the signal (the higher the signal, the more lights will be on)

Signal detection mode:
1. Press the button to turn on the red light and enter the 2.4G frequency band for detection, scanning the 2.4G signal source. Press the power button to cycle and adjust the sensitivity. The more white lights are on, the higher the sensitivity, which can expand the search range. Adjust the sensitivity to reduce the amount of white light on, decrease the sensitivity, narrow the detection range, and find the emission source. The top red light is the strongest signal light, and there will be a "beep beep" sound when sensing the signal (the higher the signal, the more lights will be on)
2. Press and hold the button for 5 seconds, and there will be a "beep" indicating that the alarm sound will be turned off (press and hold the button for 5 seconds to restore the alarm sound)

Camera detection mode:
1. Press the button to enter infrared mode (it is recommended to turn off the room lights). The four infrared lights will remain on. Move the instrument up, down, left, and right to scan the surrounding environment and observe through the dedicated filter attached to the device. If there is a camera lens in front of you, you will notice a very strong bright spot flickering;
2. Press the power button to control the speed of the red light flashing (there are 5 levels). The frequency of the LED light flashing will increase with each press, and you can choose according to your personal preference.
