Garmin GPSMAP 4008 Installation Instructions Manual page 8

The Garmin Marine Network Cable:
• The Garmin Marine Network Cable has a locking ring that secures the cable to the
chartplotter or marine network device. Because of the size of this locking ring, it is not
connected to the network cable at the factory to make it easier to install on your boat.
• Once the cable is run to the chartplotter or network device, snap the locking ring together
around the connector and insert the rubber washer as indicated on the instructions
packaged with the cable.
