5.1 Power On/Off and Sensitivity Adjustment
To power on the device, rotate the Power ON/OFF & Sensitivity Tuner knob clockwise. The device will activate. To adjust sensitivity, continue rotating this knob. Increasing sensitivity widens the detection range, while decreasing it reduces the range, allowing for more precise localization of signals. Rotate counter-clockwise to power off.
5.2 RF Signal Detection
For detecting wireless signals (e.g., from hidden cameras, GPS trackers, GSM bugs), ensure the RF antenna is attached. Turn on the device and adjust the sensitivity. Move the detector around the area of concern. The RF Signal Detection Indicator and Signal Strength Indicator will illuminate, and the device may vibrate or beep, indicating the presence and strength of a wireless signal. A stronger signal indicates closer proximity to the source.

5.3 Magnetic Field Detection
To detect magnetic GPS trackers or other magnetic devices, attach the GS probe. Activate the magnetic detection mode using the Detection Mode Toggle. Sweep the probe over surfaces where magnetic devices might be hidden, such as under vehicles or furniture. The Magnet Detection Indicator will activate upon detecting a magnetic field.
5.4 Hidden Camera Lens Detection (Laser Scanning)
To find hidden camera lenses, activate the laser detection mode. Look through the View Finder on the detector while sweeping the area with the device. Hidden camera lenses will appear as bright red reflection points due to the detector's LED laser technology and special optical lens filters. Adjust the LED Light Switch to control the flashing speed of the infrared light for better visibility.
