There is a sticker on the rear site of each MagicKey 2.
On this picture you can see the console front view and the situation of each MagicKey 2.
Stick component 1 in the hole over the on/reset button of your console, like on the photo.
Now move the disk break to the right and hold it. Stick component 2 to the left site of the disk break, as shown.
And last, put a Game or Swap Magic disc into your PlayStation, push the On/Reset button and insert component 3 into the 1mm gap situated in the back left site of your console.
When component 3 was inserted correctly the disc automatically starts to rotate!
If the disc does not rotate after you have inserted component 3 move the component a little bit to the left and to the right until the disc rotates!
