Which component is not typically found in a fire department radio?

A fire department radio is primarily designed for communication purposes, facilitating quick and efficient communication between firefighters and command centers during emergencies. The key components of a fire department radio typically include a built-in speaker for audio output, an antenna for effective signal transmission, and a push-to-talk switch that allows users to transmit their communications easily.

The absence of a video screen is significant in the context of radio communication. Fire department radios prioritize voice communication over visual display, as the primary function is to relay information quickly and reliably in urgent situations where visual distractions can be detrimental. While some advanced communication devices may incorporate screens for additional functionalities, traditional fire department radios do not include them, focusing instead on the essential elements of voice transmission and reception.
