Electrical Connections
- Power Supply: Connect the radio to a 13.8 Volt DC power source. Ensure the wiring is of adequate gauge and protected by an appropriate fuse.
- Antenna Connection: Connect a marine VHF antenna to the antenna connector on the rear of the unit. Use high-quality coaxial cable and ensure the connection is watertight.
- GPS Antenna: The GX1800G features a built-in 66-channel GPS receiver, eliminating the need for an external GPS antenna in most installations. Ensure the radio has a clear view of the sky for optimal GPS signal reception.
- Optional Connections: The radio supports optional connections for an external speaker, NMEA0183/2000 data, and a remote access microphone (e.g., Standard Horizon RAM4 microphone, model SSM-70H).
MMSI Registration
To utilize the Digital Selective Calling (DSC) features, you must obtain and program a Maritime Mobile Service Identity (MMSI) number into your radio. Contact your national telecommunications authority or a relevant boating organization for information on obtaining an MMSI number. Follow the on-screen prompts in the radio's menu to enter your MMSI.

- GPS Navigation: Utilize the built-in GPS for waypoint navigation, compass display, and viewing GPS status pages directly on the radio's screen.
- Intercom: If a second station (e.g., RAM4 or RAM4X) is connected, the intercom feature allows communication between the main radio and the remote station.
- Night Mode: Activate Night Mode for optimized display visibility in low-light conditions.
Maintenance
Regular maintenance ensures the longevity and reliable performance of your GX1800G radio.
- Cleaning: Clean the radio's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the display is free of salt residue for clear visibility.
- Waterproof Integrity: The GX1800G is IPX8 submersible, rated for 1.5 meters (4.92 feet) for 30 minutes. While highly water-resistant, ensure all caps and covers (e.g., for optional connections) are securely fastened to maintain its waterproof integrity.
- Connection Checks: Periodically inspect all cable connections for corrosion or damage. Ensure the antenna connection is tight and free of moisture.
