What is the function of the Squelch Button?

Explanation:
Squelch control manages whether the receiver mutes background noise until a real signal is detected. Pressing the squelch button toggles this feature on or off: with it on, you hear only transmissions that rise above the squelch threshold, keeping static quiet; with it off, you hear all noise and weak signals. This is different from increasing volume (which changes loudness), adjusting frequency (which changes the channel), or enabling an emergency beacon (a separate function).
