Global Positioning System (GPS) Device (Not Included)
Cobra 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 to the black
wire of the GPS interface cable.
3. Bond the NMEA out positive wire to the red
wire of the GPS interface cable.
NOTE
When bonding the wires, make sure connections
are secure and properly insulated.
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.

Your CobraMarine VHF radio is set up to connect auxiliary devices for navigation,
convenience, and added versatility. As is the case with the antenna, choosing these
devices is best done with the advice and guidance of a knowledgeable dealer.
Standard connectors are provided on the front and back of the transceiver.
Microphone Attachment
Connect the Microphone to the cord socket located
at the right side of the front of the transceiver.
To Connect The Microphone Attachment:
1. Align the connector and push it firmly into
the socket.
2. Tighten the captive nut to hold the connector
in place.
3. Slide the waterproof sleeve over the nut until it
seats in the recess around the socket.
External Speaker (Not Included)
An External Speaker can provide greater volume to
hear messages than the speaker incorporated in the
CobraMarine transceiver.
To Install An External Speaker:
Connect the speaker lead to the standard jack on the back of
the transceiver.
