Things You'll Need
Instructions
Remove the small screw to the left side of the back of the Pokéwalker. Set the screw aside carefully.
Remove the back of the Pokéwalker. Put this in a safe place in case you wish to use it again; if you decide to switch your Pokéwalker to a strap, for example, you will need the original back of the Pokéwalker.
Place the back with the belt clip on the back. Reinsert the screw and tighten it. Now you are ready to clip it on your belt and use the Pokéwalker.
