What is the PTT button used for?

Explanation:
Push-To-Talk opens the microphone circuit to start a radio transmission. When you press and hold the PTT, you key the transmitter so your voice is broadcast on the chosen channel; releasing it returns the radio to receive mode. This setup keeps conversations orderly because only one person can transmit at a time. It isn’t used to adjust volume, reboot the device, or toggle encryption—those functions are handled by other controls.
