There is a sliding button on the front ( that opens the film cartridge compartment )
just insert a new film cartridge, ( it comes with a built in battery ) which will power up the camera, and spew out the dark cover, prepping the camera for your first photo.
Polaroid cameras are powered by a battery located inside the film catridge. Changing the film on your camera will give it power, if that does not work, your polaroid film may be expired, or your camera might be broken. good luck!
