Q: Does the Wii U GamePad have a Sensor Bar?
A: Yes. When using the Wii U GamePad in Wii Mode, the Sensor Bar, located at the top of the Wii U GamePad, is turned on.
If the icon on the Wii Menu is erratic, disappears and reappears, or is not functioning as expected, it may indicate that the Sensor Bar on your TV Is conflicting with the Sensor Bar on the Wii U Gamepad. Moving the Wii U GamePad, or disconnecting the Sensor Bar connected to the TV, may resolve this issue.
Q: What is the recommended operating distance when using the Wii U GamePad with a Wii Remote?
A: Between one and three feet.
