WARNING This equipment is intended to be electrically grounded. Your
Macintosh is equipped with a three-wire grounding plug—a plug that
has a third (grounding) pin. This plug will fit only a grounded AC
outlet. This is a safety feature. If you are unable to insert the plug into
the outlet, contact a licensed electrician to replace the outlet with a
properly grounded outlet. Do not defeat the purpose of the grounding
plug!
