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
ofthatenergyisreectedbacktotheradar.
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
.
3. On the lower-right portion of the screen, select
Transmit Radar. A “Spinning Up” message
appears for a few moments, then the radar
begins painting an image.
