Using a Torx-Security T-15 screw driver, loosen the screws a little at a time evenly on each screw (process described below):

This process is done by slightly unscrewing a screw at one corner and moving to the screw at the diagonal corner next to unscrew slightly.

Then move to the opposite corners and repeat the process.

Continue until all of the screw are completely removed.

Remember to loosen opposite corners first to equalize the pressure on the springs. Do not completely unscrew one screw at one time. Unscrew each screw a little at a time.
