INSTRUCTIONS

Important Safety Information

WARNING

Failure to follow these warnings, cautions, and notices could result in personal injury, damage to the vessel or device, or poor product performance.

See the Important Safety and Product Information guide in the product box for product warnings and other important information.

The radar transmits electromagnetic energy. To avoid possible personal injury, damage to the vessel or device, or poor product performance, 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.

To avoid possible personal injury, do not look directly at the antenna at close range when the radar is transmitting. 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.

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 2).

• The radar beam spreads vertically 11.5° above and

11.5° 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.

CAUTION

This device should be used only as a navigational aid. Using the device for any purpose requiring precise measurement or direction, distance, location, or topography may result in personal injury or damage to the vessel.

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 to avoid damaging the vessel.

Tools Needed

• #2 Phillips screwdriver

• 5 mm hex wrench

• Drill

• 15 mm (19/32 in.) drill bit

• 32 mm (11/4 in.) drill bit (optional)

• 17 mm (21/32 in.) wrench and torque wrench

• 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 1).

Secure the included mounting template to the surface at the

mounting location, along the bow-stern axis, as indicated on the template.

Drill the mounting holes using a 15 mm (19/32 in.) drill bit.

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 (11/4 in.) drill bit, and route the cables through the surface (optional) (Wiring and Connection

Considerations, page 2).

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 1) and prepare the mounting surface (Preparing the Radar Mounting Surface,

page 2).

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.

Apply the included Petrolatum Primer to the threads of the

four threaded rods. Insert the threaded rods through the mounting surface and

into the radar base, and tighten them using a 5 mm hex wrench.

Align the waveguide on the pedestal with the socket on

the bottom of the antenna , and slide the antenna onto the pedestal.

Secure the antenna to the pedestal by tightening the captive

hex bolts under the antenna arm. 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.

To avoid damaging the pedestal, you should stop tightening the threaded rods when they no longer turn easily.

From under the mounting surface, place the included plastic

shoulder washers over the threaded rods and into the holes.

Place the flat washers , lock washers , and hex nuts

on the threaded rods. 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 (Mounting the Radar, page 2).

Remove the protective cover from the waveguide on the

top of the pedestal.

Wiring and Connection Considerations

It may be necessary to drill 32 mm (11/4 in.) holes for routing the power, network, or grounding 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 you must make the routing hole 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 you must cut the network cable.

• The ground cable is not included, and must connect to a water ground location, not the negative terminal of the battery (Grounding the Radar, page 3).

• 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 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.
