4. Setup and Charging
4.1 Initial Charge
Before first use, fully charge the T15 detector. Connect the provided Type-C data cable to the charging port on the device and to a standard USB power source (e.g., computer, wall adapter). The charging light will indicate the charging status. A full charge typically takes about one hour.
4.2 Attaching the Lanyard
Attach the lanyard to the hanging rope hole for convenient carrying and to utilize the vibration induction anti-theft feature.
5. Operating Instructions
5.1 Power On/Off
Press and hold the On/Off key (refer to Figure 3.1) to power the device on or off.
5.2 Adjusting Sensitivity
The T15 features five levels of sensitivity adjustment. Use the Signal Strength Adjustment Button (refer to Figure 3.1) to increase or decrease sensitivity. More blue lights indicate higher sensitivity, allowing for detection of weaker signals or from greater distances. Lower sensitivity is useful for pinpointing the exact location of a strong signal source.

5.3 Wireless Signal Detection (RF/WiFi/GPS)
Extend the antenna for optimal performance. The detector will scan for wireless signals within the 1MHz to 6.5GHz frequency range, including WiFi, RF, and GPS signals. As you approach a signal source, the signal strength indicators (blue lights) will increase. Adjust sensitivity to narrow down the search area.


5.4 Infrared Camera Detection (Anti-Capture)
Activate the infrared detection mode (using the Mode Button). Look through the viewfinder on the detector. Hidden cameras, especially pinhole cameras, often emit infrared light that is invisible to the naked eye but visible through the T15's viewfinder as bright red dots.

5.5 Magnetic Field Detection
The T15 can detect magnetic fields, which is useful for locating magnetic GPS trackers or other devices often attached to vehicles or metallic surfaces. Activate the magnetic detection mode. Move the detector slowly over suspected areas. The magnetic mode light will illuminate, and the device may provide an audible alert when a magnetic field is detected.
5.6 Vibration Induction (Anti-Theft Alarm)
To use the anti-theft alarm, activate the vibration mode (using the On/Off and vibration mode keys). Hang the detector on a door handle or other object. If the object is subjected to external force (e.g., someone trying to open the door), the detector will sound an alarm.

5.7 LED Lighting
The built-in LED lights can be activated to serve as a flashlight, useful in low-light conditions or emergency situations. Use the Mode Button to cycle to the LED lighting function.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the detector in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery: For optimal battery life, charge the device regularly, even if not in frequent use. Avoid fully discharging the battery for extended periods.
- Antenna: Handle the extendable antenna carefully to prevent bending or damage.
7. Troubleshooting
- Device not turning on: Ensure the battery is charged. Connect to a power source using the Type-C cable and try again.
- No signal detected:
- Ensure the antenna is fully extended for RF detection.
- Increase the sensitivity level.
- Move closer to the suspected area.
- False alarms:
- Decrease the sensitivity level, especially in areas with many legitimate wireless signals (e.g., Wi-Fi routers, mobile phones).
- Ensure you are in the correct detection mode for the type of device you are looking for.
- Infrared detection not working: Ensure you are looking through the viewfinder and that the infrared detection mode is active.
If you encounter persistent issues, please refer to the Warranty and Support section for assistance.

9. User Tips
- Scan Regularly: For continuous privacy protection, make it a habit to scan new environments (hotels, rental cars, meeting rooms) upon arrival.
- Systematic Search: When searching for hidden devices, conduct a systematic scan of the area. Start with high sensitivity to cover a broad area, then reduce sensitivity to pinpoint the exact location once a signal is detected.
- Check Common Hiding Spots: Pay extra attention to common hiding spots for cameras and listening devices, such as smoke detectors, air vents, power outlets, decorative items, and behind mirrors.
- Use Lanyard for Anti-Theft: When traveling, use the lanyard to hang the detector on your hotel room door handle for an added layer of security against unauthorized entry.
- Conserve Battery: Turn off the device when not in use to conserve battery life.
