5. Setup
5.1. Charging the Device
- Connect the provided USB Type-C charging cable to the charging port at the bottom of the detector.
- Plug the other end of the USB cable into a compatible USB power source (e.g., wall adapter, computer USB port).
- The device will fully charge in approximately 2.5 hours. A full charge provides 20–45 hours of scanning time, depending on the mode used.
6. Operating Instructions
6.1. Power On/Off
- To power on: Press and hold the Power button (usually the bottom button) for 3 seconds.
- To power off: Press and hold the Power button for 3 seconds.
6.2. RF Detection Mode (Wireless/Bluetooth/Radio Frequency)
This mode detects active wireless signals from hidden cameras, GPS trackers, and audio bugs. No app, Bluetooth, or Wi-Fi connection is required for the detector's operation.
- Power on the device. The default mode is typically RF detection.
- Adjust sensitivity using the Sensitivity/Mode button (usually the top button). Higher sensitivity (more lights illuminated) detects signals from a greater distance, while lower sensitivity helps pinpoint the exact location.
- Scan the area slowly. The detection lights will illuminate, and the device will emit audible beeps or vibrate (depending on settings) when a signal is detected. The intensity of the lights and frequency of beeps/vibrations increase as you get closer to the source.
6.3. Infrared (IR) / Lens Detection Mode
This mode helps locate hidden camera lenses, including pinhole and night-vision cameras, by reflecting light off their optics.
- Press the Power button to cycle to the Infrared detection mode. The device will emit red lights from the front.
- Look through the optical viewfinder/lens on the device.
- Slowly scan suspicious areas (e.g., smoke detectors, alarm clocks, air vents, mirrors). Hidden camera lenses will appear as bright red dots when viewed through the viewfinder.
- Press the Sensitivity/Mode button to cycle through different flashing patterns (slow blink, fast blink, solid) of the red lights to enhance visibility of reflective lenses.
6.4. Magnetic Detection Mode
This mode is used to find magnetic GPS trackers, which are often attached to vehicles or other metal surfaces.
- Press the Power button to cycle to the Magnetic detection mode.
- Slowly move the device, particularly the magnetic probe (if included and attached), along surfaces where trackers might be hidden (e.g., under car chassis, inside vehicle compartments).
- The device will indicate detection through lights and sound/vibration when a magnetic field is identified.
6.5. Shake Alarm Mode
Activate this mode to use the device as a motion-sensitive alarm, ideal for securing personal belongings or entry points.
- While the device is on, press and hold the Sensitivity/Mode button until a countdown appears (e.g., 10 seconds).
- Place the device on a stable surface, such as a hotel room doorknob, a bag, or a drawer, during the countdown.
- Once the countdown finishes, the alarm is armed. If the device is moved or disturbed, it will trigger a loud alarm and flashing lights.

7. Maintenance
- Keep the device clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Store the device in a cool, dry place when not in use.
- Recharge the battery regularly, even if not in frequent use, to maintain optimal battery health.
8. Troubleshooting
8.1. Detector Beeping Nonstop
If your detector is beeping continuously without an obvious threat, it might be picking up ambient signals. Try the following:
- Turn off your personal Wi-Fi and mobile phone to eliminate interference.
- Step back from windows, as external signals can sometimes be detected.
- Adjust the sensitivity level to a lower setting to narrow down the detection range.
- Refer to the full user manual for more detailed troubleshooting steps.
