How do I turn off the wah effect with a Dunlop Crybaby?

I recently bought a Dunlop Crybaby and I cant figure out how to turn off the effect. Is there a certain angle that the pedal has to be in? Is there a button I'm not seeing. I want to be able to play my guitar with the pedal plugged in but I want it to sound like the pedal isn't plugged in. Can anyone help?|||The button is on the very front of the pedal right underneath the front edge. It is designed to be pressed when you push the pedal all the way forward. Push the pedal all the way forward until it stops and then press down on the forward edge until you hear a click. Do the same thing to turn the effect back on.
