and Connections
Public Address Speaker (Not Included)
Speaker/PA Cable
At times, it may be handy to address other boats or give instructions to line handlers on the dock. Your CobraMarine VHF radio can be switched to operate in the Public Address mode through an attached PA speaker.
To Install a Public Address Speaker:
1.Connect the PA speaker positive (+) wire to the rose red wire coming out of the standard speaker/PA wire harness.
2.Connect the PA speaker negative
NMEA/IO Cable
Global Positioning System (GPS) Device (Not Included)
Cobra Electronics strongly recommends that you obtain and connect a GPS device to your CobraMarine VHF radio. By having a GPS connected, your position will
be continuously indicated on the LCD and, most importantly, it will be included automatically in any DSC distress message you may need to send. That will
take the “search” out of “search and rescue.”
To Install a GPS Device:
1.Install the GPS device in a convenient location according to its manufacturer’s directions.
2.Bond the NMEA out negative
3.Bond the NMEA out positive (+) wire of your GPS to the NMEA in positive (+) wire (white) of the MR F80 NMEA/IO interface cable.
NOTE
When bonding the wires, make sure connections are secure and properly insulated to prevent electrical arching.
4.Connect the new combination cable to the GPS device and to the back of the transceiver.
