The UHF/VHF key on the PCL performs transmissions on UHF and VHF depending on push direction.

• A. Up for VHF, Down for UHF
• B. Push center to engage both
• C. Push top to toggle between frequencies
• D. Up for UHF, Down for VHF

Answer: (D)

The UHF/VHF key uses push direction to select which band you transmit on. Pushing it upward activates transmissions on UHF, while pushing it downward activates transmissions on VHF. This makes the control intuitive: the higher position corresponds to the higher-frequency UHF, and the lower position corresponds to the lower-frequency VHF. A center push to engage both or any other mapping would not match how this control is designed, so the Up for UHF and Down for VHF setup is the correct behavior.
