Anti-Lost Device Instructions 1. Power On/Off: On: Press and hold the button for about 3 seconds. You'll hear three "Beep Beep" signals, and the indicator light will flash rapidly for 10 seconds. If there's no connection or button press, it will flash every two seconds for 30 seconds before turning off. Off: Press and hold the button for about 3 seconds. You'll hear a long "Beep" signal, and the indicator light will turn off. (The following operations apply to Android on Redmi 5 Plus, Android version 9.6.3.0, and Apple iPhone 6S Plus, iOS version 11.3.1. If the system is different, it should be subject to the actual mobile phone used, or there may be other updates without further notice.) 2. Add Device: Turn on Bluetooth on your phone, open the app to skip the power-on screen and go directly to the "Add Device" interface. Click the "Add New Device" icon. After searching for a new device, click Auto-connect. (You can also edit the device name if needed.) After connecting, click the alarm icon; you'll hear the anti-lost device's "Beep" alarm. You can then locate the device. The "Beep" sound can ring continuously. Clicking the alarm icon again stops the sound. In the settings interface, you can choose the alarm signal and alarm distance. Click "System Settings" to view the recording file and set the double-click option. 3. Take a Photo: Use the camera function and click the anti-lost device to activate the photo function. 4. Positioning: The positioning function only retains the location when the anti-lost device is disconnected from the phone; the location record can be found in "Lost Record." To use this function, you must turn on GPS and keep your phone connected to the network.
