When connecting a Merlin aerial to the antenna terminal, cut off the MCX connector and
expose 20 mm of braid. Twist this and connect to the ‘antenna shield’ terminal. Connect the
centre core to the ‘antenna’ terminal. Take care to avoid short circuits from stray strands of
shield wire.
Over-riding pushbuttons or keyswitches connected to terminals 5 & 6 and 14 & 15 must be
