The G5 Simulator works as a standalone training device, not as an accessory that connects to a clinical AED. The instructor verifies the battery is installed, configures language and scenario options via the wireless remote, positions the iCPR feedback device on a CPR manikin's chest, and connects the training electrode pads. Students then perform the rescue sequence: power on the trainer, attach the training pads to the manikin, follow voice prompts, and perform CPR compressions. The iCPR feedback device monitors compression rate and depth in real time and triggers coaching prompts through the trainer's audio. The instructor pauses for teaching moments via the remote and selects new scenarios between students.
