and the radio is configured to the desired working channel (and, if requested by the coast
station, free signal can be heard in the speaker), press the Call ARQ key.
The printer responds by printing:

display indicates that the transmitter is delivering RF output to the aerial. When successful
connection has been established the 'Tx' keyboard indicator lamp shines steady light and the
