Apple 12/600PS manual 147

WARNING Avoid touching the surface of the printer’s controller board with hands or tools to avoid damaging or scratching the printed circuits.

3Grasp the metal frame of the controller board and slide it out of the printer.

Place the board next to the printer. (When you put on the grounding wrist strap, you want to be able to reach the controller board easily.)

IMPORTANT Put on a grounding wrist strap before handling the SIMM or any internal printer parts. The strap grounds you to the printer, preventing any static discharge that might harm the board or printer. Wearing the strap cannot harm you. If you haven’t got a grounding wrist strap, you can purchase one from a computer dealer.

4Wrap the end of the grounding strap that does not have copper foil on it around your wrist.

The strap’s light adhesive coating keeps it attached to your wrist, while allowing for easy removal.

5Remove the backing from the piece of copper foil at the other end of the strap.

6Attach the copper-foil end of the strap to the metal surface on the inside of the printer by pressing the adhesive backing against the metal.
