External Devices And Connections

Your CobraMarineVHF 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.

Installation And Start-Up

Global Positioning System (GPS) Device (Not Included)

Cobra® strongly recommends that you obtain and connect a GPS device to your CobraMarineVHF 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.”
