There's no guarantee that the flash unit is still good or that the battery still has a charge (chances are good though). There should be a button on the front to activate the flash charging circuit. Go ahead and press that. You should hear the whine of the capacitor charging and after a bit you should see the indicator LED light up on the back. You should NOT have to hold the front button down. If the capacitor won't charge without the button being held down, toss the camera and find another. With the back off, you should see a small sprocket just under the view hole and above the rectangular cavity. The film advance wheel should spin easily since there is no film inside. When there is film in the camera and you advance the film with the wheel, the teeth on the edge of the film spin the small sprocket. This action resets the release button. Since there’s no film in the camera now, go ahead and spin the small sprocket towards the right. You should feel the tension build and then the sprocket should lock once the release button is set. Now press the release button. You should see a flash.



If you didn’t hear the whine, it’s most likely a bad battery. Replace the battery with a fresh one and repeat. If the flash doesn’t fire, toss the camera and get another one.
