The AED Trainer 3 reflects the unique functionality of the Philips HeartStart® FR3 AED, and provides a realistic training experience for emergency responders to deliver optimal therapy when facing cardiac arrest. The instructor can change scenarios by pressing the buttons on the device itself or by using an optional remote control. During each scenario, the remote control lets the instructor pause, change, or introduce new challenges, to test how students respond to a variety of situations, enhancing the learning experience.
