PTT

PTT is an abbreviation for Push-To-Talk.
It is a function or device that allows the user to activate the microphone and start speaking with a simple press of a button.
This function is often used in communication systems such as radios, intercom systems, military headsets, etc.

The user holds down the PTT button, speaks into the microphone, and upon releasing the button, the system stops transmitting sound.
PTT is an essential element in tactical situations where efficient and controlled communication is needed.
