NFC is activated on the mobile phone (see the manufacturer's operating instructions)
The mobile phone's screen is switched on and unlocked (see the manufacturer's operating instructions)
If your mobile phone supports wireless charging, it will be automatically charged via NFC when it is connected or replaced. A requirement for this is that the mobile phone is on the mat More.
If you want to charge a mobile phone without connecting it to the multimedia system, lay it on the mat without beforehand unblocking the screen.
