2.1 장치 충전
Before first use, or if the device does not power on, ensure it is fully charged. The K20 detector comes with a Type-C charging port. Connect the provided charging cable to the device and a suitable USB power source. A red indicator light will illuminate during charging and turn off once charging is complete.

2.2 안테나 부착
The K20 detector includes two types of antennas for different detection modes:
- RF 안테나: For wireless signal detection, screw the small black RF antenna into the left-side port labeled 'RF'.
- Magnetic Probe (GS Probe): For magnetic field detection, connect the flexible magnetic probe into the top-middle port labeled 'GS'.

3. 사용 설명서
3.1 전원 켜기 및 감도 조정
To power on the device, rotate the knob switch on the top clockwise. This knob also controls the sensitivity. Rotate clockwise to increase sensitivity and counter-clockwise to decrease it. Adjust the sensitivity to a level where the device is not constantly alarming in a clear environment, typically the lowest 2-3 levels, to avoid false positives.
3.2 RF Signal Detection
This mode is used to detect wireless signals from hidden cameras, listening devices, and other transmitting bugs.
- RF 안테나가 단단히 고정되어 있는지 확인하십시오.
- Turn on the detector by rotating the top knob. The device will automatically enter RF signal detection mode.
- Adjust the sensitivity knob counter-clockwise until the green LED lights stop flashing and the device stops beeping. This sets the baseline for the environment.
- Slowly scan the area. When the detector approaches a wireless signal source, it will emit continuous alarms or vibrations, and the signal strength LED bar will increase, indicating a successful detection.
- Inspect the identified object to determine if it is a spy device.

3.3 자기장 감지
This mode is specifically designed to locate magnetic tracking devices, often found hidden in vehicles or on metal surfaces.
- Ensure the magnetic probe (GS Probe) is securely connected to the top-middle port.
- Turn on the detector by rotating the top knob.
- Press and hold the 'M' button for 3-4 seconds until the blue GS pilot light illuminates and the white LED light at the end of the magnetic antenna turns on.
- Slowly move the magnetic probe close to suspected areas (e.g., under car seats, bumpers, luggage). When the probe is 0-5 inches away from a magnetic object, the signal strength LED bar will intensify to red, and an alarm will sound.
- Detection distance depends on the object's size and magnetic strength: bigger, stronger magnets are detected from afar; smaller ones up close.
Video: Demonstrates the magnetic field detection feature of the JMDHKK K20, showing how to attach the GS probe and detect magnetic objects.

3.4 Camera Lens Finder
This function helps identify hidden camera lenses, including wired, wireless, pinhole, and infrared cameras, by reflecting light off their lenses.
- Turn on the detector by rotating the top knob and adjust sensitivity to the lowest level.
- Briefly press the 'M' button to activate the red LED lights on the back of the detector. Press again to turn them off. Long press to change the flash frequency of the LED lights. Choose a frequency that suits you.
- 배치하다 view finder (the circular lens on the front) under one eye.
- Slowly scan the area, looking through the view finder. Any hidden camera lens will reflect the red LED light, appearing as a bright, distinct spot.
- Manually verify if the bright spot is indeed a hidden camera.
