On an RTS Key Panel, pushing down on the switch performs which action?

• A. Listens
• B. Switches mode
• C. Mutes
• D. Talks

Answer: (D)

The switch on an RTS key panel is a push-to-talk control. When you push down, you complete the transmit circuit and your microphone becomes live, so your voice is sent over the channel. Releasing returns you to listening. This behavior—speaking only while the switch is pressed—is the defining use of push-to-talk on two-way communication devices. The other options describe listening without pressing, switching modes, or muting, which would require different controls.
