Instructions
Turn on your PlayStation 2. Insert your Pelican wireless controller receiver into the "Player 1" controller port on the front of your PlayStation 2. This receiver inserts into the controller port the same way the cable for any regular controller does.
Flip the power switch on your Pelican wireless receiver to "On."
Insert the batteries (either the ones that came with your wireless controller or ones you've purchased yourself) into the battery compartment on the back of your Pelican wireless PS2 controller.
Flip your Pelican controller's power switch to "On." You can now use the controller to play PS2 games.
