Using Radar
When you connect your chartplotter to an optional Garmin marine radar such as a GMR 404/406 or a GMR 18, you can view more information about your surroundings. The Garmin marine radar connects through the Garmin Marine Network and shares radar data with all networked chartplotters.
The Garmin marine radar transmits a narrow beam of microwave energy as it rotates in a 360º pattern. When the transmitted energy contacts a target, some of that energy is reflected back to the radar.
Warning: The marine radar transmits microwave energy that has the potential to be harmful to humans and animals. Before beginning radar transmission, verify that the area around the radar is clear. The radar transmits a beam approximately 12° above and 12° below a line extending horizontally from the center of the radar. Avoid looking directly at the radar, because the eyes are the most susceptible part of the body.
To turn on the radar:
1.When you power the network on, the radar warms up. A countdown is provided to alert you when the radar is ready. From the Home screen, press Radar > Cruising.
NOTE: As a safety feature, the radar enters standby mode after it warms up. This gives you an opportunity to verify that the area around the radar is clear before beginning radar transmission. The microwave energy transmitted by the radar can potentially be dangerous.
2.When the message “Ready to Transmit” appears, press or touch MENU.
