Using Radar - Garmin GPSMAP 4000 series Owner's Manual

When you connect your chartplotter to an optional Garmin marine radar such as a GMR 404/406
or 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 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 on the network, the radar warms up. A countdown is provided to alert you
when the radar is ready. From the Home screen, press Radar >
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 scanner is clear before beginning radar transmission.
The microwave energy transmitted by the scanner can potentially be dangerous.
2. When the message "Ready to Transmit" appears, press and release the
not press and hold the button, or you may turn off your chartplotter), or press MENU.
3. On the bottom right of the screen, select Transmit
for a few moments, then the radar begins painting an image.
