Press and hold the Power Switch Key (T2) or the designated power button (K18) to turn the device on or off. The display screen will illuminate upon activation.
6. Operating Instructions
6.1 T2 Detector Operation

Figure 7: Detailed diagram of the T2 Detector's buttons and ports.
Controls Overview:
- Power Switch Key: Turns the device on/off.
- Enhanced Gear Key: Increases sensitivity or adjusts settings.
- Downshift Key: Decreases sensitivity or adjusts settings.
- Vibration/Ringing Mode Switch: Toggles between silent (vibration) and audible (ringing) alerts.
- Strong Magnetic Probe Mode: Activates detection for magnetic fields (e.g., GPS trackers).
- Camera Detection Mode: Activates laser scanning for hidden camera lenses.
- AI Intelligent Detection Mode: Automatically identifies suspicious signals and provides alerts.
Detection Modes:
- RF Signal Detection (Eavesdropping/Tracking):
Activate the appropriate mode. Slowly scan the area. The signal indicator diagram on the display screen will show signal strength. A white display indicates a safe, non-alarm state. As you approach a suspicious signal source, the indicator pin will fluctuate in the green area, and an alarm may sound or vibrate. Proximity to the source will cause the pointer to jump to the yellow 'WeChat signal area' for enhanced detection. Finally, in the red area (level 10), the device has locked onto the suspicious signal source.

- GPS Locator Accurate Detection:
Use the Strong Magnetic Probe Mode to detect magnetic fields emitted by GPS trackers, especially those hidden in vehicles. The detector will alarm when a magnetic field is detected, helping to quickly locate and remove the device.

- Camera Detection (Laser Scanning):
Activate Camera Detection Mode. The device will emit laser light. Look through the detector's viewing window while scanning the room. Hidden camera lenses will reflect the laser light, appearing as bright red dots. This method helps detect pinhole cameras, watch cameras, and other hidden optical lenses.

- AI Intelligent Detection Mode:
This mode automatically identifies suspicious signals. It can store suspicious signals in memory and trigger an alarm if suspicious signals accumulate five times, providing an automatic equipment alarm.

Sensitivity Adjustment:
Use the Enhanced Gear Key to increase sensitivity for detecting weaker or more distant signals. Use the Downshift Key to decrease sensitivity to pinpoint the exact location of a strong signal and avoid false positives.
6.2 K18 Detector Operation

Figure 13: The K18 Detector highlighting its three core functions: Magnetic Field Signal Detection, RF Wireless Signal Detection, and Camera Detection.
Detection Modes:
- RF Wireless Signal Detection:
Turn on the K18 and adjust the sensitive adjustment knob. Scan the area for radio frequency signals. The device will indicate signal strength through light, sound, or vibration alarms. The signal strength detection levels are: White (Normal), Green (Weak), Orange (Suspicious), Red (Danger).
- Magnetic Field Signal Detection:
Attach the magnetic probe. Activate the magnetic field detection mode. Use the probe to scan surfaces, especially in vehicles, for hidden magnetic GPS trackers. The device will alert you upon detecting a magnetic field.
- Camera Detection (Laser Scanning):
Activate the camera detection feature. The K18 will emit a laser. Look through the filter lens on the device while sweeping the area. Hidden camera lenses will reflect the laser light, appearing as bright points, allowing you to locate them.

Figure 14: The K18 Detector's laser detection feature, capable of accurately finding various cameras.
Sensitivity Adjustment:
The K18 features a sensitive adjustment knob switch. Rotate the knob to increase or decrease the detection sensitivity. Higher sensitivity is useful for detecting weaker signals or scanning larger areas, while lower sensitivity helps pinpoint the exact location of a strong signal source.

8. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or solvents.
- Storage: Store the detector in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: Recharge the battery regularly, even if the device is not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Handle with Care: Avoid dropping the device or subjecting it to strong impacts.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Low battery; Device fault | Charge the device fully. If still unresponsive, contact support. |
| No signal detected | No active signals; Sensitivity too low; Device fault | Increase sensitivity. Ensure you are in an area where signals might be present. Check if the antenna (K18) is properly attached. |
| Frequent false alarms | High sensitivity; Interference from legitimate devices (Wi-Fi, mobile phones) | Decrease sensitivity. Move away from known signal sources. Temporarily turn off personal electronic devices. |
| Camera lens not visible with laser | Incorrect scanning angle; Lens too small/obscured | Scan slowly and thoroughly from different angles. Ensure the room is dimly lit for better visibility of reflections. |
| Magnetic field detection not working (K18) | Magnetic probe not connected; Mode not activated | Ensure the magnetic probe is securely connected and the correct mode is selected. |
10. User Tips
- Scan Systematically: When searching for devices, divide the area into sections and scan each section thoroughly. Don't rush the process.
- Minimize Interference: Before scanning, turn off your own mobile phone, Wi-Fi, and Bluetooth devices to avoid false positives from your personal electronics.
- Adjust Sensitivity: Start with medium sensitivity and increase it if no signals are found. Decrease sensitivity as you get closer to a signal to pinpoint its exact location.
- Check Common Hiding Spots: Pay extra attention to smoke detectors, power outlets, lamps, clocks, air vents, plush toys, and under furniture. For vehicles, check under seats, bumpers, and inside the dashboard.
- Use Laser Detection in Low Light: For camera detection, dimming the lights in the room can make the reflections from hidden lenses more visible.
- Practice: Familiarize yourself with the device's functions and indicators in a known safe environment before using it in critical situations.
