•Shorten the strap by cutting along the grooves on the inner surface. You can do this for instance with scissors. If you are unsure of the correct length, cut the pieces one by one and test the length after cutting each piece. Cut in turns from both sides of the strap to keep the sides equally long. Be careful not to shorten the strap too much.
•Replace the spring bars into the last pin holes of both sides of the strap.
•Attach the buckle to the strap by placing the spring bars into the holes in the strap. In both sides of the buckle are holes for two different positions. This can be used for fine tuning of the strap length. Make sure that the spring bars are positioned straight in the buckle.
