Configurar
- Carregando o dispositivo: Connect the provided charging cable to the device's charging port and a compatible USB power source. The device's indicator will show charging status. Ensure the device is fully charged before first use for optimal performance.
- Attaching the RF Antenna: Screw the RF Antenna into the designated port on the top of the main unit. This antenna is crucial for wireless signal detection.
- Attaching the GS Probe: Connect the GS Probe (Magnetic Field Probe) to its dedicated port on the top of the main unit. This probe is used for detecting magnetic trackers.
Instruções de operação
1. Wireless Signal Detection (RF Detection)
This mode detects radio frequency signals emitted by wireless cameras, listening devices, GPS trackers, and other transmitting bugs. It is ideal for sweeping rooms, offices, or vehicles for active surveillance devices.
- Ativação: Turn on the device and select the RF detection mode.
- Ajuste de Sensibilidade: Use the sensitivity control knob to adjust the detection range. Start with higher sensitivity in open areas and decrease it as you narrow down a signal source.
- Digitalização: Slowly sweep the device across the area of interest, paying close attention to walls, furniture, electronic devices, and hidden compartments. The signal strength indicator on the display will increase as you approach a signal source.
- Alertas: The device will provide visual (LED indicators) and/or audible/vibration alerts when a signal is detected.

2. Magnetic Field Detection
This function is specifically designed to locate magnetic GPS trackers and other devices that attach using magnets, commonly found on vehicles or metallic surfaces.
- Ativação: Ensure the GS Probe is attached. Select the magnetic field detection mode.
- Digitalização: Slowly move the GS Probe along surfaces where magnetic devices might be hidden, such as under car chassis, wheel wells, or metallic furniture.
- Alertas: The device will indicate the presence of a magnetic field through visual and/or audible alerts. The closer the probe is to a magnetic source, the stronger the indication.

3. Hidden Camera Lens Finder (Infrared Scanning)
This mode helps identify hidden pinhole cameras, even if they are not actively transmitting, by detecting their reflective lenses using infrared light.
- Ativação: Select the camera lens finder mode. The device will emit a red infrared light.
- Digitalização: Look through the red viewing window on the device while slowly scanning the area. Pay attention to objects like smoke detectors, air vents, picture frames, electrical outlets, and small holes.
- Identificação: A hidden camera lens will appear as a bright, reflective red dot when viewed through the device's window.

4. AI Auto Scan Mode
The AI Auto Scan mode provides an intelligent, automated scan for various threats, simplifying the detection process.
- Ativação: Select the AI Auto Scan mode. The device will automatically cycle through detection methods.
- Monitoramento: Place the device in an area you wish to monitor. It will continuously scan for signals and alerts you to any detected threats.
Manutenção
- Limpeza: Use um pano macio e seco para limpar o dispositivo. Não utilize produtos de limpeza abrasivos ou solventes.
- Armazenar: Guarde o dispositivo em local fresco e seco, longe da luz solar direta e de temperaturas extremas.
- Cuidados com a bateria: Para prolongar a vida útil da bateria, evite descarregá-la completamente com frequência. Carregue o dispositivo regularmente, mesmo quando não estiver em uso, para manter a saúde da bateria.
- Manuseie com cuidado: Evite deixar o dispositivo cair ou submetê-lo a impactos fortes, pois isso pode danificar os componentes internos.
Solução de problemas
| Problema | Possível causa | Solução |
|---|---|---|
| O dispositivo não liga. | Bateria fraca ou sem carga. | Carregue o dispositivo completamente usando o cabo de carregamento fornecido. |
| Poor RF signal detection. | Antenna not properly attached or low sensitivity setting. | Ensure the RF antenna is securely attached. Increase sensitivity using the control knob. |
| Magnetic detection not working. | GS Probe not attached or damaged. | Verify the GS Probe is securely connected. If still not working, the probe may be damaged and require replacement. |
| Camera lens finder not showing red dots. | Not scanning correctly or no hidden cameras present. | Ensure you are looking through the red viewing window and slowly scanning the area. Test with a known camera (e.g., phone camera) to verify function. |
