To transmit over the UHF radio, which action is required?

Explanation:
Transmitting over UHF requires engaging the transmit function on the UHF/VHF control. On the PCL, the UHF/VHF key is a two-position switch: push it upward to enable transmission, then release it to return to receive. Pushing downward does not initiate transmit. The other actions don’t start a transmission: turning the UHF knob on the audio panel adjusts volume or squelch, and selecting COM 1 on the UFCP chooses which radio you’re using but doesn’t key the transmitter. So pushing the UHF/VHF key upward on the PCL is the necessary step to transmit.
