What is the first step required to use the Loudhailer?

The first step required to use the Loudhailer involves squeezing the handle. This action is essential because squeezing the handle activates the device, allowing it to amplify sound effectively. The Loudhailer is designed to project the user's voice over a larger distance, and the handle actuation is the initial engagement needed to start the sound amplification process. This indicates that the device is operational and ready for use, which is crucial for effective communication, especially in noisy environments or during emergencies.

Understanding this step is key, as it establishes the proper functioning of the Loudhailer before further actions, such as pressing the button or adjusting volume settings, can be effectively executed.
