To set up your Wii Balance Board, you may need to Synch your Wii Balance Board with your Wii Console. To do so:

1. Start Winter Sports 2 and proceed to the Main Menu (where you can choose between 'Career', 'Competitions', 'Single Event', etc.).

2. Open the flap on the front of the Wii. Below the RESET button, notice the red button with the word 'Synch' engraved on it.

3. Open the area on the bottom of the Wii Balance Board where the batteries are housed, notice a small round button in the bottom left corner.

4. Press and hold both buttons simultaneously for a few seconds.

5. Use your Wii Remote and Wii Balance Board to follow the instructions that will appear on the screen after you synch up the Wii Balance Board. These instructions are very simple and just serve to allow your Wii to calibrate the Wii Balance Board..

If you are still having trouble you can try calibrating the Wii Balance Board again by selecting 'Options' from the Main Menu and then selecting 'Troublshooting'.
