5. Setup
5.1 Charging the Device
- Connect the provided USB charging cable to the charging port on the detector.
- Plug the other end of the USB cable into a standard USB power adapter (not included) or a computer's USB port.
- The Charging Indicator Light will illuminate during charging.
- A full charge typically takes approximately 1 hour and provides up to 25 hours of continuous use or 30 days of standby time.
5.2 Powering On/Off
- To power on, press and hold the ON/OFF Button until the indicator lights illuminate.
- To power off, press and hold the ON/OFF Button again until the lights turn off.
6. Operating Instructions
The detector features three main detection modes. Use the Function Switching Button to cycle between modes.
6.1 RF Wireless Signal Detection (Anti-Eavesdropping)
This mode detects wireless signals emitted by hidden cameras, listening devices, and other RF transmitting bugs.
- Power on the device.
- Extend the Antenna fully.
- Press the Function Switching Button until the RF signal detection mode is active (indicated by specific lights).
- Adjust the sensitivity using the Signal Strength Adjustment Button. Start with lower sensitivity to pinpoint sources, then increase for broader scanning.
- Slowly scan the area. The Signal Detection Sensitivity LEDs will light up, and an audible alert may sound, increasing in intensity as you approach a signal source.
- When the LEDs are fully lit and the alarm is continuous, you are very close to a transmitting device.

6.2 Hidden Camera Detection (Optical Lens Scan)
This mode helps locate hidden camera lenses, even if they are not actively transmitting a signal.
- Power on the device.
- Press the Function Switching Button until the optical lens detection mode is active (the LED Lights will flash).
- Look through the Viewfinder.
- Slowly scan the area, paying close attention to objects like smoke detectors, clocks, power outlets, and decorative items.
- If a camera lens is present, it will reflect the flashing red LED lights, appearing as a bright red dot through the viewfinder.

6.3 Magnetic Field Detection (GPS Tracker Detection)
This mode is specifically designed to detect magnetic GPS trackers, which are often covertly attached to vehicles.
- Power on the device.
- Press the Function Switching Button until the magnetic field detection mode is active (the Magnetic Mode Light will illuminate).
- Slowly move the detector close to surfaces where a magnetic tracker might be hidden, such as under a car, inside bumpers, or under seats.
- The device will vibrate and the Magnetic Field Detection indicator will light up when a magnetic object is detected.

7. Maintenance
7.1 Cleaning
- Wipe the device with a soft, dry cloth.
- Do not use abrasive cleaners or solvents.
7.2 Storage
- Store the device in a cool, dry place away from direct sunlight.
- If storing for an extended period, charge the device periodically to maintain battery health.
8. Troubleshooting
- Device not turning on: Ensure the device is fully charged. If the issue persists, contact customer support.
- No signal detected: Ensure the antenna is fully extended for RF detection. Adjust sensitivity settings. Move closer to potential sources.
- False alarms: In RF mode, the detector may pick up legitimate signals from Wi-Fi routers, mobile phones, or other wireless devices. Reduce sensitivity or move away from known signal sources to differentiate.
- Optical detection not working: Ensure the LED lights are flashing. Scan slowly and thoroughly, looking for distinct red reflections.
