If an external display unit is not to be used
connect the supplied power only interface cable
to the Power / NMEA port.
Locate the RF, power and/or data cables into
the rubber grommets pushing them firmly to the
base of each slit. Each cable is pushed into the
grommet slit which lies directly in front of the
