[Notes]
1. Batteries are optional.
2. Do not use a car's starting battery, as its voltage is too high. Doing so may cause the megaphone to malfunction.
3. Battery Life assumes the megaphone is used for 30 minutes per day.
4. Audible Range assumes the megaphone uses new batteries and is operated on a quiet street. It varies depending on factors such as battery consumption, ambient noise, wind direction, and obstacles.
