Radar



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 parts of the body.
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 GMR 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 the radar.

1.  With the chartplotter off, connect your radar as described in the radar installation instructions.
2.  Turn on the chartplotter. 

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. 

3.  From the Home screen, select Radar.
4.  Select Cruising, Harbor, offshore, or Sentry. 

A countdown message appears while the radar is starting up, and the “Ready to Transmit” message appears.

5.  Select Transmit.

A “Spinning Up” message appears for a few moments, and the radar begins painting an image.

From the Radar screen, select To Standby.

1.  Press and release   to open the display screen.
2.  Complete an action:

•  Select Transmit Radar.
•  Select Radar to Standby. 

The zoom scale, also called the radar range, represents the distance from your position (the center) to the 

outermost ring. Each ring represents an even division of the zoom scale. For example, if the zoom scale is set 

at three miles, each ring represents one mile from the center out.
