Using Radar
When you connect your chartplotter to an optional Garmin marine radar such as a GMR 404/406 or
a GMR 18/24, you can view more information about your surroundings. The 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 360
pattern. When the transmitted energy contacts a target, some of that energy is reected 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. Power on the network. The radar warms up and a countdown is provided to alert you when the
radar is ready.
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 harmful to humans and animals.
2. From the Home screen, touch Radar > Cruising. The “Ready to Transmit” message appears.
3. Complete one of the following actions:
Touch Menu.
Press and release the Power key on the chartplotter. Do not hold the key, or you may shut
down the chartplotter.
4. Touch Transmit Radar. A “Spinning Up” message appears for a few moments, then the radar
begins painting an image.
To turn off the radar:
1. Complete one of the following actions:
Touch Menu.
Press and release the Power key on the chartplotter. Do not hold the key, or you may shut
down the chartplotter.
2. Touch Radar to Standby.
