Instructions
Run the small string loop on the wrist strap through the hole at the bottom of the Wii Remote (this hole is located directly under the Remote's accessory port). The loop should enter the hole and come out on the other side.
Run the wrist strap through the small string loop and pull on the strap. This will tie the strap to the Wii Remote.
Test the strap by placing your wrist inside the strap and using the plastic latch to tighten the strap. Let the Wii Remote dangle from your wrist to make sure the strap is secure.
