Operating Instructions

I. RF Signal Detection Mode

Working Principle

The RF detector is a wireless signal receiving device that operates based on wireless characteristics. It detects signals emitted by nearby wireless devices within a large range. As the detector approaches the wireless signal source, the signal strength increases, and the alarm becomes stronger, allowing for the accurate location of the wireless signal source. Importantly, the product itself does not emit any wireless signals. When signals from other devices reach a certain strength, the detector triggers an alarm to alert personnel to inspect the area where the alarm is activated. This helps in detecting and finding suspicious devices.

Operate Instructions

  1. Install the RF antenna onto the RF Antenna Port 9.
  2. Turn the On/Off Knob 3 to power on the detector. It will automatically enter RF Signal Detection mode (indicated by the MS Pilot Light 6 turning red).
  3. Adjust the Sensitivity Knob 3 to calibrate sensitivity in your environment. Turn it clockwise to raise sensitivity. If the Signal Strength LED Bar 7 fully lights up and the detector keeps beeping, rotate the Sensitivity Knob counterclockwise until it flashes green and stops beeping. This confirms proper calibration of detection sensitivity.
  4. Short press the 'M' button to choose your desired alarm mode (Sound ? or Vibration ?).

The detector will automatically detect RF signals emitted by any RF sources, such as a wireless spy device. The signal strength increases as the detector approaches the RF source, with more lights appearing on the signal strength LED bar. When the detector emits long continuous alarms or vibrations, indicating successful detection of the RF source, you need to personally inspect the identified object to verify whether it is a spy device. In some cases, you may need to repeat the above steps and adjust the sensitivity for accurate detection of RF sources.

II. Magnetic Field Detection Mode

Working Principle

Our product features a magnetic induction probe located at the top of the magnetic detection antenna. In practical applications, GPS tracking devices often use magnetic mounts for easy installation, meaning they have strong magnetic properties. When our product is set to magnetic detection mode, the magnetic induction probe will trigger an alarm if it approaches a magnetic object. This alerts detection personnel to inspect the area where the alarm is activated, achieving the goal of detecting magnetic GPS tracking devices.

Operate Instructions

  1. Install the GS Probe 1 onto the GS Probe Port 10.
  2. Turn the On/Off Knob 3 to power on the detector.
  3. Long press the 'M' button for 3-4 seconds until the blue GS pilot light illuminates, and the torch light at the end of the probe lights up.
  4. Short press the 'M' button to choose your desired alarm mode (Sound ? or Vibration ?).

[Diagram Description: An illustration shows the JMDHKK K18+ RF Detector with the GS probe installed.

III. Camera Finder (camera detector)

Working Principle

Our detector's View Finder utilizes a lens treated with special filters, leveraging the principle of light reflection from camera lenses coated with light-reflective material. Positioned on the back of the detector, 6 red LED lights emit either a flashing or steady light. When observing through the View Finder, users can detect the "bright spot" reflected by hidden camera lenses, regardless of whether the hidden camera is activated.

Operate Instructions

  1. Turn the On/Off Knob 3 to power on the detector and set it to the minimum sensitivity position.
  2. Short press the LED Lights Switch 15 to illuminate the six red LED lights on the back.
  3. Move around and use one eye to peer through the View Finder 4. Any hidden camera lens will reflect the red LED light, appearing as a bright spot. Verify manually if the bright spot is indeed a hidden camera.

Battery and Charging

The detector features a built-in 1000mA Lithium battery, which can be charged using the provided power charger and Type-C charging cable. Other phone chargers are also allowed to use.

The Charging Pilot Light indicates charging status, turning on during charging and off once fully charged. A full charge typically takes approximately ±2.5 hours.

WARNING: Please note that the RF detector is not intended for daily use like a cellphone or tablet. Prolonged periods of inactivity may result in reduced battery life or inability to charge. We recommend regularly charging your detector to maintain battery life and ensure optimal performance.

Frequently Asked Questions and Solutions

Q1: What should I do if the device is not turning on?

A: Ensure that the device is charged. Any mobile phone charger, power bank, or laptop can be used to charge the device.

Q2: Why is the device continuously beeping in signal detection mode?

A: Ensure that there are no known signal sources nearby (e.g., mobile phones, Smart Watch, Wi-Fi routers...). If the issue persists, adjust the sensitivity knob counterclockwise until the alarming stops.

Q3: How do I detect hidden cameras with the device?

A: Turn on the LED Lights using the LED Lights Switch, then use the View Finder to identify reflections from hidden camera lenses, appearing as bright spots.

Q4: What should I do if the device is not detecting hidden cameras effectively?

A: Ensure proper positioning and adjust the angle of the device for optimal detection. (Tips: For optimal results, create a low-light environment by turning off lights, closing curtains or shutters, etc. To achieve the best detection angle, either look directly through the View Finder or rotate the detector ±15° in front of your eyes. Excessive angle between the detector and camera may diminish detection accuracy.)

Q5: How do I detect GPS trackers with the device?

A: As GPS trackers typically have strong built-in magnets for easy attachment to metal parts, set the device in Magnetic Field Detection mode, scan suspicious areas of your vehicle where GPS trackers may be attached, investigate thoroughly and repeat the scanning process in different areas and angles to ensure comprehensive coverage.

Q6: The device is unable to detect magnetic objects or GPS trackers?

A: First, ensure that the device is set to Magnetic Field Detection Mode. Next, consider that the detection distance may vary depending on the magnetic strength of the object being detected; please try checking the detected area multiple times. Additionally, the device's magnetic probe is equipped with polarized magnetic sensing components; try rotating the device to different orientations to utilize the different directions of the magnetic probe for detection.
