Instructions
Insert the batteries that came with your Wii-mote into the battery compartment on the bottom of your system. This compartment is accessible through the rear of the Wii-mote.
Turn on your Wii. You can only program a controller to your system if the system is actually on.
Locate the sync buttons on both your Wii-mote and your Wii console. On the console, the sync button is near the SD memory card slot on the front of the device. On the Wii-mote, the sync button is in the same compartment, on the back of the unit, that the batteries are held in.
Press the "Sync" button on your Wii-mote one time. Press the "Sync" button on your Nintendo Wii one time. The lights on both devices will blink for a few seconds, and then stop. The Wii-mote is now programmed to communicate with your Nintendo Wii.
