It’s the WiFi Bug Detection by default, indicator “WIFI” lights up. If the detector keeps beeping, please set your cell phone to airplane mode and turn off WiFi, routers and other wireless devices before detecting. ②Select mode: Short press the Power Switch button to switch the mode you want. There are six modes to switch: · WiFi Bug Detection, · Full-band Detection, · Infrared Detection · Magnetic Detection · AirTag Detection · Camera Detection ③ Adjusting sensitivity: Short press the Sensitivity Adjustment button to adjust the sensitivity of the detection (only in WiFi Bug DetectionFull-band Detection ) and there are 6 different gears to adjust. And you can also adjust the speed of the red light when in Camera Detection. ④ Silence mode: Long press the Sensitivity Adjustment button for 3 seconds to switch to Silence Mode. Long press the Sensitivity Adjustment button 3 seconds to release the Silence Mode. Please fully charge the product before first use. -1--2- Tag AirTag detection mode Signal/Sensitivity indicator WiFi bug detection mode 2 Red lights Red light adjustment w Infrared light 6 signal intensity display lights Adjustable display lights(5 levels of sensitivity) Sensitivity adjustment Infrared light adjustment (fast or slow) Power switch Mode selection WIFI camera detection Full-band detection DC 5V Charging Port Charging Progress Indicator WiFi Bug Detection (More pricise) . Mode Activation Press and hold the Power Switch for 3 seconds. The "WIFI" indicator will light up, entering WiFi Bug Detection Mode, used to detect 2.4GHz wireless signals (commonly used in detecting hidden WiFi cameras). . Detection Process Move the detector slowly and continuously around the area. As you get closer to a hidden camera or signal source: · Signal strength lights will flash more rapidly · Beeping sound becomes more frequent . Importance Notes Short press the Sensitivity Adjustment button to toggle through sensitivity levels · Higher sensitivity = broader detection range · Lower sensitivity = more precise location Remark: ①Before detecting at home or hotel, the mobile phone must be set to air-plane mode, and the wireless router must be turned off to reduce interference. ②Before detection in the car, the mobile phone must be set to the air-plane mode, the car should be turned off and do not start (there will be signal interference on the car navigation when it is started), and the car should be parked in a remote place. -3- -4- Full-band Detection (Wider frequency range) . Mode Activation Press and hold the Power Switch for 3 seconds, then short press the Mode Selection button once. The "F-band" indicator light will turn on, indicating the detector has entered Full-band Detection Mode, capable of detecting signals in the 1MHz–6GHz frequency range. . Detection Process Move the detector slowly and continuously around the area. As you approach a signal-emitting source: · Signal intensity lights will flash more rapidly · Beeping sounds will become more frequent . Importance Notes Short press the Sensitivity Adjustment button to adjust detection sensitivity: · High sensitivity allows broad scanning · Low sensitivity helps narrow down the exact source Remark: ①Before detecting at home or hotel, the mobile phone must be set to air-plane mode, and the wireless router must be turned off to reduce interference. ②Before detection in the car, the mobile phone must be set to the air-plane mode, the car should be turned off and do not start (there will be signal interference on the car navigation when it is started), and the car should be parked in a remote place. Strong Magnetic Detection . Mode Activated Press and hold the Power Switch for 3 seconds, then short press the Mode Selection button 3 times. The "magnet sign" indicator light will turn on, and the device enters Strong Magnetic Detection Mode. . Detection Process Move the detector slowly and close to surfaces (especially metallic ones). As you approach a hidden magnetic device: · The signal indicator lights will flash more · The beeping frequency will increase · The closer you are, the stronger the signal . Important Notes This mode uses fixed sensitivity, manual adjust- ment of sensitivity is not available. Remarks: ①Mainly for magnetic suction bugs like GPS tracker, pinhole camera and eavesdropper etc. ②Successful detection of a magnetic bug depends on the strength of the magnet and its distance from the Bug Detector. So you need to scan it as close as possible. S…
