•
WARNING
The radar must be mounted out of range of people, with the vertical beam width above head height. To avoid
exposure to harmful radio frequency (RF) levels, the radar must not be mounted closer to people than the
minimum safe distance value listed in the product specifications.
• The radar should be mounted high above the ship’s keel line with minimal blockage of the radar beam.
Obstructions may cause blind and shadow sectors or generate false echoes. The higher the installation
position, the farther the radar can detect targets.
• The radar should be mounted on a flat surface or a platform that is parallel to the vessel's water line and is
sturdy enough to support the radar's weight. The weight for each model and antenna is listed in the product
specifications.
• The radar must be mounted in a location where it can be connected to power, water ground, and network.
• The radar beam spreads vertically 11.5°above and 11.5°below the radar's radiating element. On vessels
with higher bow angles at cruise speed, the installation angle can be lowered to point the beam slightly
downward to the waterline while at rest. Shims can be used if necessary.
• The radar should be mounted away from heat sources, such as smoke stacks and lights.
• The radar should be mounted at a different level than horizontal spreaders and mast crosstrees.
• To avoid interference with a magnetic compass, the radar should not be mounted closer to a compass than
the compass-safe distance value listed in the product specifications.
• Other electronics and cables should be mounted more than 2m (6.5ft.) from the radar beam path.
• GPS antennas should be either above or below the radar beam path.
• The radar should be mounted at least 1m (40in.) from any transmitting equipment.
• The radar should be mounted at least 1m (40in.) away from cables carrying radio signals such as VHF
radios, cables, and antennas.
• The radar should be mounted at least 2m (6.5ft.) away from Single Side Band (SSB) radios.

Installation Procedures
Preparing the Radar Mounting Surface
Before you can mount the radar, you must choose a suitable mounting location (Mounting Considerations,
page3).
1 Secure the included mounting template to the surface at the mounting location, along the bow-stern axis, as
indicated on the template.
2 Drill the mounting holes using a 15mm (
19
/
32
in.) drill bit.
3 If you need to run the power and network cables through the mounting surface, select a location along
the center channel indicated on the template, drill a pass-through hole for the cables using a 32mm
(1
1
/
4
in.) drill bit, and route the cables through the surface (optional) (Wiring and Connection Considerations,
page6).
4 Remove the mounting template from the surface.
Mounting the Radar
Before you can mount the radar, you must select a mounting location (Mounting Considerations, page3) and
prepare the mounting surface(Preparing the Radar Mounting Surface, page4).
1 Place the radar onto the mounting surface, aligning the holes on the base of the radar with the holes you
drilled when preparing the mounting surface.
2 Apply the included primer (Petrolatum Primer) to half the length of each threaded rod.
3 Insert the primed end of each threaded rod through the mounting surface and into the radar base, and
tighten them using a 6mm hex wrench.
To avoid damaging the pedestal, you should stop tightening the threaded rods when they no longer turn
easily.
4 From under the mounting surface, place the included plastic shoulder washers over the threaded rods
and into the holes.
4
5 Place the flat washers , lock washers , and hex nuts on the threaded rods.
6 Tighten the hex nuts to a torque of 14.7N-m (11lbf-ft.) to securely fasten the radar to the surface without
damaging the radar or the mounting hardware.
Installing the Antenna
Before you can install the antenna on the pedestal, you must securely mount the pedestal (Mounting the Radar,
page4).
1 Remove the protective cover from the waveguide on the top of the pedestal.
2 Remove the mounting hardware from the bottom of the antenna .
These screws and washers are used to secure the antenna to the pedestal.
3 Align the waveguide on the pedestal with the socket on the bottom of the antenna , and slide the
antenna onto the pedestal.
5
4 Secure the antenna to the pedestal using the hex screws , spring washers , and flat washers you
removed from the antenna.
5 Using a torque wrench, tighten the hex screws to 0.81kgf-m (70lbf-in or 5.83lbf-ft) to fasten the antenna to
the pedestal without damaging the antenna or the mounting hardware.
Wiring and Connection Considerations
It may be necessary to drill a hole up to 32mm (1
1
/
4
in.) in diameter for routing the power, network, or
grounding cables.
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, 32mm (1
1
/
4
in.) decorative cable grommets can be
purchased from your local Garmin dealer, or you can go to buy.garmin.com (optional).
• If needed, you can trim the grommet to enable you to route multiple 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.
• The ground cable is not included, and must connect to a water ground location, not the negative terminal of
the battery (Grounding the Radar, page10).
• 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, page10).
◦ Incorrectly extended runs of cable may cause the radar to malfunction due to insufficient power
transmission.

2 Lift the access panel up and away from the pedestal housing.
Connecting to Power Through the Voltage Converter
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. Connecting the power cable without the appropriate fuse in place voids the product warranty.
NOTICE
Do not reuse any voltage converters from previous Garmin radar models, or third party voltage converters. Using
any converter other than one included with the radar, or the correct converter purchased from Garmin or from
your local Garmin dealer may damage the radar or prevent it from turning on.
If your model is not packaged with a voltage converter, you can connect the power cable directly to the boat
battery (Connecting Directly to Power, page9).
When installing the voltage converter, observe these considerations.
• The voltage converter requires an input voltage of 10 to 32Vdc.
• You should install the voltage converter as close as possible to the power source.
• Connecting the power cable for the voltage converter directly to the battery is recommended. If it is
necessary to extend the cable, you must use the appropriate gauge of wire for the length of the extension
(Power Cable Extensions, page10).

Minimum Safe Operating Distances
When it is transmitting, the radar should be located in a position on the vessel that is at least this far
from people. IEC60936-1, clause3-27.1, specifies the maximum distances from the antenna at which radio
frequency (RF) levels can be expected.
These minimum safe distances apply for a transmitting radar with a rotating antenna, and are much larger
when the antenna is not rotating. If rotation of the antenna is obstructed for any reason, the transmitter will
automatically turn off.
