I just have the defibrillator.

Look for the model number on the back of the defibrillator. It may be under the battery. Then compare it to the pictures below.

M5071A = Adult pads for the Heartstart Onsite


M5072A = Infant/Child pads for the Heartstart Onsite

M3870A = Infant/Child Pads for the Hearstart FR2+


Philips Heartstart FRx 861304
