Installation Instructions
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 voids 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.
Opening the device may result in personal injury and/or damage to the device.
This device contains no user-serviceable parts, and should be opened only by
a Garmin
®
authorized service technician. Any damage resulting from opening
the unit by anyone other than a Garmin authorized service technician will not
be covered by the Garmin warranty.
NOTICE
When drilling or cutting, always check what is on the opposite side of the
surface.

Tools Needed
• #2 Phillips screwdriver
• 5 mm hex wrench
• Drill
• 15.0 mm (
19
/
32
in.) drill bit
• 32 mm (1
1
/
4
in.) drill bit (optional)
• 17 mm (
21
/
32
in.) wrench and torque wrench
• 3.31 mm² (12 AWG) copper wire to ground the radar housing and voltage
converter, if applicable (the length depends on the distance from the radar
to ground)
• Marine sealant
Mounting Considerations
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 and antenna is listed in the
product specifications.
• The device must be mounted in a location where it can be connected to
power, water ground, and the Garmin Marine Network (Wiring and
Connection Considerations, page 3).
• 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.
• 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
carrying radio signals such as VHF radios, cables, and antennas.
• The device should be mounted at least 2 m (6.5 ft.) 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, page 2).
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 32 mm (1
1
/
4
in.)
drill bit, and route the cables through the surface (optional) (Wiring and
Connection Considerations, page 3).
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, page 2) and prepare the mounting surface
(Preparing the Radar Mounting Surface, page 2).
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 Petrolatum Primer to the threads of the four threaded
rods.
3
Insert the threaded rods
À
through the mounting surface and into the
radar base, and tighten them using a 5 mm hex wrench.
