I enter the four symbols to synchronise the GamePad to the Wii U console but it keeps failing. What should I do?
Disconnect the Wii U console from the power supply and ensure that both the AC adapter connector and DC plug are clear of dust or dirt. After ten seconds, plug the Wii U AC Adapter into the Wii U console again, making sure it is firmly inserted. After turning on the Wii U console, try the GamePad synchronisation process again.
If this doesn't solve your problem, please get in touch with our Nintendo Service Centre.
