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.

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. To avoid possible personal injury, 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.

Software Update

You must update the Garmin chartplotter software when you install this device. For instructions on updating the software, see your chartplotter owner’s manual at support.garmin.com.

Tools Needed

  • Drill
  • 9.5 mm (3/8 in.) drill bit
  •  32 mm (1 1/4 in.) drill bit (optional)
  • 4 mm (5/32 in.) hex wrench
  • 13 mm (1/2 in.) wrench and torque wrench
  •  Marine sealant

Mounting Considerations
To complete the installation, you need the appropriate fasteners, tools, and mounts. These items are available at most marine dealers.

  • It is highly recommended that the device is mounted out of range of personnel, with the horizontal 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 between the vessel and the radar beam. Obstructions may cause blind and shadow sectors, or generate false echoes. The higher the installation position, the farther the radome 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.
    Most radar beams spread vertically 12.5° above and 12.5° below the radome’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. Use shims if necessary.GARMIN GMR Fantom 18x-24x Dome Rader 1
  • 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 ½ 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. For Single Side Band (SSB) radios, increase the distance to 2 m (6 ½ ft.).

Mounting the Radar

Before you mount the radar, you must review the mounting location considerations and select a mounting location.
NOTE: The supplied M8 x 1.25 x 60 threaded rods can be used on mounting thicknesses of 5 to 30 mm (3/16 to 1 3/16 in.) (recommended). For surfaces over 30 mm (1 3/16 in.), use longer threaded rods.

  1. If you are not installing the device on a pre-drilled Garmin compatible radar mount, use the included mounting template to drill four 9.5 mm (3/8 in.) mounting holes.
  2. Connect the power cable to the power port and the network cable to the network port .GARMIN GMR Fantom 18x-24x Dome Rader 2
  3. Press the cables into any of the guide grooves on the bottom of the case, and secure them using a cable hold-down plate . The cables should be bent or twisted as little as possible.
  4. Using the arrow on the bottom as a reference, position the radome on the mounting surface aligned to the front of the vessel.
    NOTE:If you choose not to align the dome with the front of the vessel, you can adjust the front-of-boat offset after the dome is installed (Setting the Front-of-Boat Offset, page 3).
  5. Apply the included anti-seize compound to the threads of the four M8 x 1.25 x 60 threaded rods.
  6. Insert the four threaded rods into the mounting holes on the bottom of the radome. Up to 50 mm (2 in.) of the threaded rods may extend below the radome.
  7. Apply a bead of marine sealant on the mounting surface around each mounting hole.
  8. Fasten the radome to the mounting surface using threaded rods , flat washers , spring washers , and hex nuts .GARMIN GMR Fantom 18x-24x Dome Rader 3
  9. Using a torque wrench, tighten the nuts to 13.7 to 18.6 N-m (10 to 14 lbf- ft.)

Wiring and Connection Considerations

It may be necessary to drill 32 mm (11/4 in.) holes for routing the power and network cables.

  • When routing multiple cables through the same hole, you must route the network cable before the power cable.
  • 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 the power and network 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.
  • 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.
  • You should install the power cable as close to the battery source as possible.
    • If it is necessary to extend the power cable, you must use the appropriate wire gauge (Power Cable Extensions, page 3).
    • Incorrectly extended runs of cable may cause the radar to malfunction due to insufficient power transmission.

Connecting the Power Cable

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 voids the product warranty.

  1. Route the power cable from the device to the power source.
  2. Connect the red wire to the positive (+) battery terminal, and connect the black wire to the negative (-) battery terminal.
  3. If you have not already done so, connect the power cable to the device by turning the locking ring clockwise.

Power Cable Extensions
Connecting the power cable 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.

Distance Wire Gauge
2 m (6.5 ft.) 16 AWG (1.31 mm²)
4 m (13 ft.) 14 AWG (2.08 mm²)
6 m (19.5 ft.) 12 AWG (3.31 mm²)

Connecting to a Device or to the Marine Network

You can connect the radar either directly to a radar-compatible Garmin device or to a Garmin Marine Network to share radar information with all connected devices.
NOTE: Not all Garmin devices are compatible with the Garmin Marine Network. See the installation instructions or owner’s manual provided with your device for more information.

  1. Route the network cable to your compatible Garmin device.
  2. If you have not already done so, install the locking rings and o-rings on Nthe end of the network cable.
  3. Select an option:
    1. If the Garmin device is not compatible with the Garmin Marine Network, connect the network cable to the port labeled RADAR.
    2. If the device is compatible with the Garmin Marine Network, connect the network cable to the port labeled NETWORK.

Radar Operation

All functions of this radar are controlled with your Garmin chartplotter. See the Radar section of your chartplotter’s owner’s manual for operating instructions. To download the latest manual, go to support.garmin.com. If you have more than one radar on your boat, you must be viewing the radar screen for the radar you want to configure. Measuring the Potential Front-of-Boat Offset The front-of-boat offset compensates for the physical location of the radar scanner on a boat, if the radar scanner does not align with the bow-stern axis.

  1. Using a magnetic compass, take an optical bearing of a stationary target located within viewable range.
  2. Measure the target bearing on the radar.
  3. If the bearing deviation is more than +/- 1°, set the front-of-boat offset.

 

Setting the Front-of-Boat Offset
Before you can set the front-of-boat offset, you must measure the potential front-of-boat offset.
The front-of-boat offset setting configured for use in one radar mode is applied to every other radar mode and to the Radar overlay.

  1. From a Radar screen or the Radar overlay, select Menu > Radar Setup > Installation > Front of Boat.
  2. Select Up or Down to adjust the offset.
