XFT-120G AED (Automated External Defibrillator) Trainer is specifically designed to train first-aid personnel before they use a real clinical AED. The AED Trainer completely simulates the operation of AED in the training guide and training program, but does not deliver high voltage electric shock, protecting the safety of trainees. It can be used to help first-aid personnel get familiar with AED and master some necessary basic operating skills of using AED in the first aid process.
