Important Safety Information
WARNING
See the Important Safety and Product Information guide in the product box for
product warnings and other important information.
The radar transmits electromagnetic energy. Ensure that the radar is installed
according to the recommendations in these instructions and that all personnel
are clear of the path of the radar beam before transmitting. When properly
installed and operated, the use of this radar conforms to the requirements of
ANSI/IEEE C95.1-1992 Standard for Safety Levels with Respect to Human
Exposure to Radio Frequency Electromagnetic Fields.
When the radar is transmitting, do not look directly at the antenna at close
range; eyes are the most sensitive part of the body to electromagnetic energy.
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.
CAUTION
This device should be used only as a navigational aid. Do not attempt to use
the device for any purpose requiring precise measurement of direction,
distance, location, or topography.
Always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
When selecting a mounting location, observe these considerations.
• It is highly recommended that the device is mounted out of range of
people, with the vertical beam width above head height. To avoid exposure
to harmful radio frequency (RF) levels, the device should not be mounted
closer to people than the maximum safe distance value listed in the
product specifications.
• The device 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 device 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
device's weight. The weight for each model is listed in the product
specifications.
• The radar beam spreads vertically 11.5° above and 11.5° below À 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.

NOTICE
When drilling or cutting, always check what is on the opposite side of the
surface.
•
Registering Your Device
The device should be mounted away from heat sources, such as smoke
stacks and lights.
The device should be mounted at a different level than horizontal
spreaders and mast crosstrees.
To avoid interference with a magnetic compass, the device 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 2 m (6.5 ft.)
from the radar beam path.
GPS antennas should be either above or below the radar beam path.
The device should be mounted at least 1 m (40 in.) from any transmitting
equipment.
The device should be mounted at least 1 m (40 in.) away from cables

GMR rdar Series Installation Instructions
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 (Power Cable
Extensions, page 4).
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 (Power Cable Extensions, page 4).
◦ Incorrectly extended runs of cable may cause the radar to malfunction
due to insufficient power transmission.
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. In addition, connecting the power cable without the appropriate
fuse in place will void 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 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 (Connecting
Directly to Power, page 3).
