What is the first action you should take to use the megaphone?

The first action to take when using a megaphone is to press the button and listen for an audible pop. This sound indicates that the megaphone is operational and ready to amplify your voice. It serves as an initial check that the device is functioning properly, allowing you to confidently use it during an emergency situation or when communication is necessary across distances.

While checking the battery status and ensuring the device is sealed correctly are important steps in the overall preparation and maintenance of the megaphone, the immediate action to confirm its readiness for use is to engage the button. Removing it from the bracket is also necessary but is typically a prerequisite to testing it for sound. Therefore, the selected initial action ensures that the operator can quickly ascertain the effectiveness of the device before proceeding further with its usage in the intended scenario.
