You turn it on, and this disembodied voice speaks to you telling you what to do.
It tells you to apply the pads to the patient's chest, then to stand clear while it analyses the heart rhythym of the patient.
Then it either tells you to start with CPR, or allow you to administer a shock. The AED operator then tells everybody to stand clear (as well as the AED telling them to) and then it says "press button to deliver shock". You press the button, it says "Shocking" and delivers a charge.
Then it re-analyses the heart rhythym, and will either have suceeded in regaining a normal heartbeat or the atrial fibrilation will have resisted the shock, in which case it tells the operator to re-begin chest compressions and rescue breaths for two cycles (usually) and then it'll start over - request you stop CPR while it reanalyses and decides whether or not to shock again.
gotta give Dr. Aed some room so he can attempt to revive the patient.
