How Your CobraMarine® C.P.S. Works
The C.P.S. contains a GPS (Global Positioning System) receiver to receive your current position (Latitude and Longitude) anywhere on Earth and convert this information to interface to any fixed mount marine VHF radio using the NMEA 0183 specifications. With it properly connected, in an emergency, your position information will be included in a DSC (Digital Selective Calling) Distress call, alerting the authorities and the vessels around you, allowing assistance to know exactly where you are.
Connecting to the Cobra MR F57 and MR F77 Marine VHF Radios
Your CobraMarine C.P.S. has been designed to Plug-N- Play with the CobraMarine MR F57 and MR F77 fixed mount marine VHF radios.
1.Simply connect the integrated plug of the C.P.S. into the GPS input jack on your MR F57 or MR F77 radio.
2.Turn on your radio and the C.P.S. will automatically be powered by the radio and will automatically acquire the GPS satellite signals.
3.The MR F57 will automatically display your current position after the C.P.S. acquires your position.
4.Since the MR F77 radio already has a built-in GPS receiver, you will need to go into the GPS setup menu and turn off the internal GPS to use the C.P.S. input.
5.Be sure to use electrical tape or heat shrink tubing to secure and water proof the connections.
