The trainer is designed to drop into an existing CPR/AED training program. The instructor charges the rechargeable battery before class, powers on the trainer (it defaults to AED Video Mode which displays full-color rescue videos), pairs the wireless remote, and connects the reusable training pads. Students then perform the rescue sequence on a standard CPR manikin: open the device, watch the LCD video while attaching pads, follow voice prompts, and deliver the simulated shock when prompted. The instructor uses the remote to select between three operating modes (AED Video, AED ECG, Manual), choose specific scenarios, and pause for teaching moments. The trainer mirrors the clinical Defibtech Lifeline VIEW so students train on the same interface they would see in a real rescue.
