External Devices And Connections
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.
External Speaker (Not Included)
An External Speaker can provide greater volume to hear messages than the speaker
incorporated in the CobraMarine microphone/speaker.
To Install An External Speaker:
1. Connect the wires to the External Speaker as follows:
Orange wire - +Positive connection
Black wire - -Negative connection (Black wire is common shared -Negative for
the External Speaker and PA output)
2. Make sure to solder, crimp, or twist the wires together firmly and use shrink
tubing or electrical tape to waterproof the connection.
Public Address Speaker (Not Included)
At times, it may be handy to hail 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 wires to the External Speaker as follows:
Red wire - +Positive connection
Black wire - -Negative connection (Black wire is common shared -Negative for the
External Speaker and PA output)
2. Make sure to solder, crimp, or twist the wires together firmly and use shrink
tubing or electrical tape to waterproof the connection.
