3
Press the cables into any of the guide grooves on the bottom of the
case, and secure them using a cable hold-down plate .
The cables should be bent or twisted as little as possible.
4
Using the arrow on the bottom as a reference, position the radome on the
mounting surface aligned to the front of the vessel.
NOTE:
If you choose not to align the dome with the front of the vessel,
you can adjust the front-of-boat offset after the dome is installed (
Setting
the Front-of-Boat Offset
, page 3).
5
Apply the included anti-seize compound to the threads of the four
M8 x 1.25 x 60 threaded rods.
6
Insert the four threaded rods into the mounting holes on the bottom of
the radome.
Up to 50 mm (2 in.) of the threaded rods may extend below the radome.
7
Apply a bead of marine sealant on the mounting surface around each
mounting hole.
8
Fasten the radome to the mounting surface using the threaded
rods , flat washers , spring washers , and hex nuts .
9
Using a torque wrench, tighten the nuts to 13.7 to 18.6 N-m (10 to 14 lbf-
ft.).
Wiring and Connection Considerations
It may be necessary to drill 32 mm (1
1
/
4
in.) holes for routing the power and
network cables.
• When routing multiple cables through the same hole, you must route the
network cable before the power cable.
• You must apply marine sealant to the hole after the cables are in place to
ensure a waterproof seal.
If you must make the routing hole in a visible location, decorative cable
grommets can be purchased from Garmin or a Garmin dealer (optional).
• If needed, you can trim the grommet to enable you to route the power and
network cables through the same hole.
• The optional grommet does NOT provide a waterproof seal. You must
apply marine sealant to the grommet after the cables are in place to
ensure a waterproof seal.
When installing the cables, you should observe these considerations.
• Cutting the Garmin Marine Network cable is not recommended, but a
field install kit can be purchased from Garmin or a Garmin dealer if you
must cut the network cable.
• To ensure safety, appropriate tie-wraps, fasteners, and sealant should be
used to secure the cable along the route and through any bulkheads or
the deck.
• You should not run cables near moving objects and high-heat sources, or
through doorways and bilges.
• To avoid interference with other equipment, you should not run network
and power cables parallel to other cables, such as radio antenna lines or
power cables. If this is not possible, the cables should be shielded with
metal conduit or a form of EMI shielding.
• You should install the power cable as close to the battery source as
possible.
◦
If it is necessary to extend the power cable, you must use the
appropriate wire gauge (
Power Cable Extensions
, page 3).
◦
Incorrectly extended runs of cable may cause the radar to
malfunction due to insufficient power transmission.
Connecting the Power Cable
WARNING
When connecting the power cable, do not remove the in-line fuse holder. To
prevent the possibility of injury or product damage caused by fire or
overheating, the appropriate fuse must be in place as indicated in the
product specifications. In addition, connecting the power cable without the
appropriate fuse in place voids the product warranty.
1
Route the power cable from the device to the power source.
2
Connect the red wire to the positive (+) battery terminal, and connect the
black wire to the negative (-) battery terminal.
3
If you have not already done so, connect the power cable to the device by
turning the locking ring clockwise.
Power Cable Extensions
Connecting the power cable directly to the battery is recommended. If it is
necessary to extend the cable, the appropriate gauge of wire must be used
for the length of the extension.

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.
