Please follow these steps to connect the monitor to WiFi:
Power on the monitor
Scan the QR code called "Add to WiFi" on the back of the monitor
On Android 11 or 12, please select "Manage router" if prompted
On some Android version you might need to tap "Tap here to sign in to network"
Wait for the WiFi Manager screen popping up. In case the WiFi manager does not appear, open 192.168.4.1 on your browser
Press "Scan for Network"
Select the WiFi network or enter it manually in case it is hidden. Please note that the monitor only supports 2.4GHz networks
Enter the password and click "connect"
Once the monitor has found an active internet connection, its LED will blink 3 times slowly
Please note that you have only around 180 seconds to go through above process before a timeout happens. In that case, restart the process by re-booting the monitor
