GPSMAP 5000 Series Owner’s ManualUsing RadarUSinGradarUsing RadarWhen you connect your chartplotter to an optional Garmin marine radar such as a GMR 404/406 ora GMR 18, you can view more information about your surroundings. The radar connects through theGarmin 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 360°pattern. When the transmitted energy contacts a target, some of that energy is reflected back to theradar.WARNING: The marine radar transmits microwave energy that has the potential to be harmful tohumans and animals. Before beginning radar transmission, verify that the area around the radar is clear.The radar transmits a beam approximately 12.5° above and below a line extending horizontally from thecenter of the radar. Avoid looking directly at the radar, because the eyes are the most susceptible part ofthe body.To turn on the radar:1. When you power the network on, the radar warms up. A countdown is provided to alert you whenthe radar is ready. From the Home screen, touch Radar > Cruising.As a safety feature, the radar enters standby mode after it warms up.
