Pull the blue handle backwards to unlock the Anti-Clamp's arms.

Place your phone screen side up on an object so it will rest level between the Anti-Clamp's arms—the bottom edge should be hanging off.

Slide the arms over the left edge of your phone, so you have access to the bottom edge.

Position the suction cups as close to the center of the bottom edge as possible.

Squeeze the cups together to create suction.
