1.1 A Brief History of Marine Radars 5
CHAPTER 1 INTRODUCTION
WARNING
See the Important Safety and Product Information in the Installation Instructions for product
warnings and other important information.
All route and navigation lines displayed on the device are intended to provide general guidance to
identify proper channels, and are not intended to be strictly followed. Always refer to the navaids
and conditions on the water when navigating to avoid groundings or hazards that could result in
vessel damage, personal injury, or death.
DonotrelysolelyontheSimpliedTargetTracking(TT)featureforcollisionavoidance.Always
pay attention to your surroundings, including other vessels, obstacles, water and weather
conditions. Never leave the helm unattended. You are responsible for the safe operation of your
boat.
1.1 A Brief History of Marine Radars
1.1.1 Basic Principles of Radars
Radar, originally an acronym for Radio Detection and Ranging, is a detection system that
determines the position and velocity of objects by transmitting radio waves outward and
processingtheradiowavesreectedofftheobjects.
1.1.2 Development of Marine Radars
Marine radars were developed during the period of the Second World War. Before its
development, seafarers had to rely on sound waves generated by a whistle, a gunshot, or
a bell sound to determine the direction and distance of obstacles when visibility is low.
Since its invention, marine radars are used to detect other vessels or land obstacles
and assist in navigation and collision avoidance at sea. A rotating antenna sweeps the
surface of water around the ship toward the horizon with a narrow beam of microwave
signals. The antenna then listens for bouncebacks of the signal to determine the bearing,
distance,andmotionofdetectedtargetsbasedonthevariationsinthereectedsignals.
The radar uses these information to map out the ship’s surroundings on the radar display
in a bird’s eye view.
1.1.3 Determining the Bearing
As the antenna rotates in the 360° circle, electronic pulses are sent out at slightly
differentbearings.Thesignals,andtheirreectedechoes,travelatthespeedof
light(roughly161,785nauticalmilespersecond),andechoesarereceivedalmost
instantaneouslywhentheyreectoffobjects.Thebearingofatargetisthereforethe
angle of the antenna at which the echoes are received.
1.1.4 Determining the Range
The range, or the distance to a target, is calculated by multiplying half the speed of light
by the time difference between the transmission and reception of a signal. The speed is
halvedbecausethesignaltraveledthedistancetwice(toandfromthetarget).

CHAPTER1 INTRODUCTION6
1.1.5 Displaying Relative Positions
The calculated relative positions of detected targets are plotted on the radar display with
the own ship position usually at the center. The plot is refreshed as the antenna rotates,
and the relative motions and speeds of targets can also be displayed.

1.4.3 Mounting Considerations
NOTICE
This device should be mounted in a location that is not exposed to extreme
temperatures or conditions. The temperature range for this device is listed in the product
specications.Extendedexposuretotemperaturesexceedingthespeciedtemperature
range, in storage or operating conditions, may cause device failure. Extreme-
temperature-induced damage and related consequences are not covered by the warranty.
When selecting a mounting location, you should observe these considerations:
• The location should be directly in front or slightly to your left as you operate your boat,
to provide optimal viewing and allow easy access to all device interfaces, such as the
control panel and the SD card slots.
• The location must be strong enough to support the weight of the device and protect it
from excessive vibration or shock.
• To avoid interference with a magnetic compass, the device should not be installed
closer to a compass than the compass-safe distance value listed in the product
specifications.
• The location must allow room for the routing and connection of all cables.
1.4.4 Bail Mounting the Device
NOTICE
Ifyouaremountingthebracketonberglasswithscrews,itisrecommendedtousea

1.5 Radar Unit Installation
CAUTION
Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or
sanding.
NOTICE
When drilling or cutting, always check what is on the opposite side of the surface.
1.5.1 Tools Needed
• Drill and drill bits
• #2 Phillips screwdriver
• 5 mm Allen wrench
• Wrench and socket set
1.5.2 Mounting Considerations
To complete the installation, you need the appropriate fasteners, tools, and mounts.
These items are available at most marine dealers.
When selecting a mounting location, observe these considerations:
• It is highly recommended that the device is mounted out of range of personnel, with
the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 detection range.
• 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.
• Most radar beam spreads vertically 12° above and 12° 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.

1.5 Radar Unit Installation 17
• 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)fromcablescarryingradiosignals
such as VHF radios, cables, and antennas.
• Thedeviceshouldbemountedatleast2m(6.5ft)fromSingleSideBand(SSB)radios.
1.5.3 Cable Considerations
Itmaybenecessarytodrill32mm(1¼in)holesforroutingthepowerornetworkcables.
• When routing multiple cables through the same hole, you must route the network
cable before the power and ground cables because of the size of the network
connector.
• 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).
• 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:
• 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.
• 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 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.
• You should install the power cable as close to the battery source as possible.
• If it is necessary to extend the cable, you must use the appropriate wire gauge.
• Incorrectly extended runs of cable may cause the radar to malfunction due to
insufficient power transmission.

CHAPTER1 INTRODUCTION18
1.5.4 Performance Monitor Notices
The performance monitor should be installed at around 10 cm from the radar.
• For open-array type radars, the performance monitor should be installed at the same
height as the antenna.
• For dome type radars, the performance monitor should be installed at the same height
as the radar.
1.6 Cable and Connection Considerations
• The cables may have been packaged without the locking rings installed. If so, you
should route the cables before you install the locking rings.
• After connecting a locking ring to a cable, make sure the ring is securely connected
and the O-ring is in place so the connection remains secure.
1.6.1 Power/NMEA 0183 Cable
• The wiring harness connects the device to power, NMEA 0183 devices, and a lamp or
a horn for visible or audible alerts.
• IfitisnecessarytoextendtheNMEA0183oralarmwires,youmustuse22AWG(.33
mm²)wire.
