You must mount the radar, connect it to power, and connect it to
the Garmin Marine Network before you can specify the antenna
size.
1
Turn on the radar and all devices connected to the Garmin
Marine Network.
An antenna-selection prompt appears on the connected
chartplotters.
NOTE:
If the entire system is being turned on for the first
time, the antenna-selection screen is part of the initial setup
process.
2
Select the installed antenna size for each open-array radar
installed on the boat.
TIP:
If you need to specify a different antenna size, while
viewing the radar screen for the radar you want to change ,
select
Menu
>
Radar Setup
>
Installation
>
Antenna
Configuration
>
Antenna Size
, and select the antenna size.
Front-of-Boat Offset
The front-of-boat offset compensates for the physical location of
the radar scanner on a boat, if the radar scanner does not align
with the bow-stern axis.
Measuring the Potential Front-of-Boat Offset
The front-of-boat offset compensates for the physical location of
the radar scanner on a boat, if the radar scanner does not align
with the bow-stern axis.
1
Using a magnetic compass, take an optical bearing of a
stationary target located within viewable range.
2
Measure the target bearing on the radar.
3
If the bearing deviation is more than +/- 1°, set the front-of-
boat offset.
Setting the Front-of-Boat Offset
Before you can set the front-of-boat offset, you must measure
the potential front-of-boat offset.
The front-of-boat offset setting configured for use in one radar
mode is applied to every other radar mode and to the Radar
overlay.

From a Radar screen or the Radar overlay, select
Menu

2
Select

or
Down
to adjust the offset.
Setting a Custom Park Position
If you have more than one radar on your boat, you must be
viewing the radar screen for the radar you want to adjust.
By default, the antenna is stopped perpendicular to the pedestal
when it is not spinning. You can adjust this position.
1
From the radar screen, select
Menu

.
2
Use the slider bar to adjust the position of the antenna when
stopped, and select
Back

*When it is transmitting, the radar should be located in a position
on the vessel that is at least this far from people.
IEC 60936-1, clause 3-27.1, specifies the maximum distances
from the antenna at which radio frequency (RF) levels can be
expected.
