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.
2
Align the waveguide
bottom of the antenna
pedestal.
3
Secure the antenna to the pedestal using the included hex
bolts
and spring washers
4
Torque the hex bolts to 0.81 kgf-m (70 lfb-in. [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 31.7 mm (1 ¼ in.) holes for routing
the power or network cable. The provided rubber cable grommet
can be used to cover a cable installation hole.
• The grommet does NOT provide a waterproof seal. To make
the grommet waterproof, marine sealant must be applied.
• If needed, the grommet can be trimmed to route both the
power and the network cable through the same hole.
• Additional cable grommets can be purchased from Garmin or
a Garmin dealer.
When installing the power and network 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, power and
network 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
Extensions).
◦ Incorrectly extended runs of cable may cause the radar to
malfunction due to insufficient power transmission.
Connecting to Power Through the Voltage Converter
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 will void the product warranty.
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 may damage
the radar or prevent it from turning on.
Some radar models require a voltage converter unit to properly
power the device. If your model is packaged with a voltage
converter, it must be installed in order for your radar to function.
If your model is not packaged with a voltage converter, connect
the power cable directly to the boat battery
to
Power).
When installing the voltage converter for an applicable radar
model, observe these considerations.
• The voltage converter requires an input voltage of 10 to
32 Vdc.
• It is recommended to 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, the appropriate gauge of wire must be used for the
length of the extension
