Installation Procedures
Preparing the Radar Mounting Surface
Before you can mount the radar, you must choose a suitable
mounting location (
).
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 15 mm (
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 25 mm (1 in.) drill bit, and route the cables
through the surface (optional) (
).
4
Remove the mounting template from the surface.
Mounting the Radar
Before you can mount the radar, you must select a mounting
location (
) and prepare the
mounting surface (
Preparing the Radar Mounting Surface
).
1
From under the mounting surface, place the included plastic
shoulder washers
À
into the holes you drilled when preparing
the mounting surface.
2
Place the radar onto the mounting surface, aligning the holes
on the base of the radar with the holes in the shoulder
washers.
3
Insert the threaded rods
Á
through the mounting surface and
into the radar base, and tighten them using a 5 mm hex
wrench.
To avoid damaging the pedestal, you should stop tightening
the threaded rods when they no longer turn easily.
4
Place the flat washers
Â
, lock washers
Ã
, and hex nuts
Ä
on
the threaded rods.
5
Tighten the hex nuts to a torque of 14.7 N-m (11 lbf-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 radar, you must
securely mount the pedestal (
).
1
Remove the protective cover from the waveguide on the top
of the pedestal
À
.
2
Align the waveguide on the pedestal with the socket on the
bottom of the antenna
Á
, and slide the antenna onto the
pedestal.
3
Secure the antenna to the pedestal by tightening the captive
hex bolts under the antenna arm.
4
Tighten the hex bolts to a torque of 7.9 N-m (6 lbf-ft.) to
fasten the antenna to the pedestal without damaging the
antenna or the mounting hardware.
Cable Considerations
It may be necessary to drill 25 mm (1 in.) holes for routing the
power or network cables.
• When routing both the power and network 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 the routing hole must be made in a visible location, decorative
cable grommets can be purchased from Garmin or a Garmin
dealer (optional).
• You must drill a 31.7 mm (1
1
/
4
in.) hole to use the optional
grommet.
• If needed, the grommet can be trimmed to enable you to
route both the network and the power cable 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 ensure a waterproof seal.
When installing the network and power 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 cutting the network cable is
necessary.
• 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.
• Cables should not be run near moving objects and high-heat
sources or through doorways and bilges.
• To avoid interference with other equipment, network and
power cables should not be run next to or 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.
• The power cable should be installed as close to the battery
source as possible.
◦ If it is necessary to extend the power cable, the
appropriate gauge of wire must be used (
).
◦ Incorrectly extended runs of cable may cause the radar to
malfunction due to insufficient power transmission.
