Things You'll Need
Instructions
Turn the unit over and remove the battery cover. Set the battery and cover aside.
Remove and set aside the four screws on the back panel. Flip the toy back over and lift out the face of the toy to reveal its inner workings. Place the front to the left of the back panel but don't remove the cable joining the two. Some of the buttons may come out with the face plate. Return them to their position on the back and keep them intact.
Pick up the small metal ball inside the back panel and wipe it down with a lint-free cloth. Place it inside the foam ring on the back panel of the device.
Pour a small amount (three to four drops) of alcohol onto your lint-free cloth and wipe the square chip on the front-side of the toy. This chip should be right next to the foam ring. Dry the chip with a dry piece of the cloth.
Flip the front cover of the device back into place, aligning the screw holes on the front with the holes on the back. There should be no gap between the two halves of the toy. Carefully flip the toy back over and screw the four screws, battery and battery cover back into place.
