External Devices
and Connections
Public Address Speaker (Not Included)
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
(-) wire to the
black/white wire coming out of the standard speaker/PA
wire harness.
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
(-) wire of your GPS to the
NMEA
in negative
(-) wire (green) of the MR F80
NMEA/IO interface cable.
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.
NOTE
Satellite acquisition time is dependent on the
GPS
device.
CobraMarine Chartplotter MC 600C Series
Your CobraMarine VHF radio is set up to connect directly to your chartplotter with a
custom accessory cable that eases the installation.
The chartplotter uses a state-of-the-art electronic chart system, designed as a
custom navigation aid. All calculations and information necessary for the navigation
are performed and displayed on the chartplotter quickly and accurately providing all
of the capabilities of a conventional GPS, but with the added benefit of a powerful
electronic chart display.
Wiring the chartplotter to the transceiver is made easy with a custom-made optional
Accessory Cable harness P/N CM 140-001. This cable has a molded 8-pin connector
that plugs directly into the appropriate connectors on the MR F80 and the MC 600C
Series.
To Install the Chartplotter:
1.
Install the chartplotter in a convenient location according to the chartplotter
owner’s manual.

page 29.
