The lights below the RADIO buttons indicates which radio is selected (has focus).
Pressing the RADIO1 (B14) and RADIO2 (B15) buttons at the same time enables automatic

the RADIO1 (B14) and RADIO2 (B15) buttons indicate which radio has TX focus (will transmit
in response to a PTT input). Transmit switching is based on the configuration options and
application control signals described later.

headphone audio being sent to the digital demodulators. Performance will be compromised
when adjusting the headphone level for operator comfort.
