Steps 4 and 5 involve handling sensitive electronics. Avoid static discharge.

Peel up the end of the black tape surrounding the main PCB assembly and very slowly and carefully begin to peel back the tape.

Watch out for ribbon cables that the tape may be adhered to. If needed, grab the ribbon cable with a pair of blunt tip tweezers as you peel back the tape.

Use extreme care while handling ribbon cables and connectors as they can be easy to damage.

Set the tape aside, as it will be placed back during reassembly.
