There were no instructions, even though its says includes 1 manual. it looks us about 2 hours to realize the for the image side - do NOT align the rods into the holes. for the button side you DO align the rods with the holes. We had to resort to youtube to find which direction the button holder were supposed to face. In the youtube video, the button holder sides are labeled A and B. On the actual unit the presses ARE NOT labeled, but the rotating part is labeled L and R.once we got it going, we are fine, but wasted about 50 pieces.
