Things You'll Need
Instructions
Unplug your wired sensor bar from your Wii console while it is powered off.
Insert the AA batteries into the wireless sensor bar (the number of batteries required varies depending on the make of the sensor bar).
Place the wireless sensor bar on top of or below your television screen in the same place you had the original wired sensor bar. The distance from the console does not make a difference. If your wireless sensor bar uses a dongle, plug it into the back of the Wii.
Power up your Wii console. Power up the wireless sensor bar by pressing the power button on the bar. The wireless bar will immediately pick up the signal from your Wii remote, and you can begin playing games.
Optionally, you can navigate to the Wii's Settings menu to calibrate the sensor bar for slightly better accuracy. When done playing, turn off the console and turn off the wireless sensor bar.
