Radar Operation - Garmin GMR FANTOM 18 Nstallation Instructions

Connecting to a Device or to the Marine Network
You can connect the radar either directly to a radar-compatible Garmin device or to a Garmin Marine Network to
share radar information with all connected devices.
NOTE: Not all Garmin devices are compatible with the Garmin Marine Network. See the installation instructions
or owner's manual provided with your device for more information.
1 Route the network cable to your compatible Garmin device.
2 If you have not already done so, install the locking rings and o-rings on the end of the network cable.
3 Select an option:
• If the Garmin device is not compatible with the Garmin Marine Network, connect the network cable to the
port labeled RADAR.
• If the device is compatible with the Garmin Marine Network, connect the network cable to the port labeled
NETWORK.

Radar Operation

All functions of this radar are controlled with your Garmin chartplotter. See the Radar section of your
chartplotter's owner's manual for operating instructions. To download the latest manual, go to
support.garmin.com.
If you have more than one radar on your boat, you must be viewing the radar screen for the radar you want to
configure.
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.
1 From a Radar screen or the Radar overlay, select Menu > Radar Setup > Installation > Front of Boat.
2 Select Up or Down to adjust the offset.
