The most common misconception is that using one requires training or judgment. Modern public-access defibrillators analyze the heart rhythm themselves and will not deliver a shock to someone who does not need it. They give spoken instructions from the moment they are switched on. The training exists to remove hesitation and to teach the pairing with compressions, not because the device is difficult.
The second misconception is that finding one is easy. Many people cannot name the nearest defibrillator to their home or workplace, and units are frequently in locked buildings outside working hours. Registered public units are listed in national and local databases which emergency call handlers use, and knowing whether your nearest one is registered and accessible at night is worth checking rather than assuming.
What the class should give you is the sequence and the confidence to use it: recognize the arrest, call emergency services, start compressions, send someone specific for the defibrillator, follow its instructions, and keep compressing between shocks. Compressions before and between shocks are what maintain circulation, and they are the part people most often stop too early.
