Scanner Installation
The following section covers the installation and setup of the GMR 18 marine radar. The GMR 18 only operates with components of the
Garmin Marine Network, and MFD's (mulit-function displays). See your Garmin dealer or the Garmin Web site for more details. To complete
the installation, you need the appropriate fasteners, tools, and mounts. These items should be available at most marine dealers. Always wear
safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding. When drilling or cutting, always check fi rst to see what is
on the other side of the surface. If you experience diffi culty with the installation, contact Garmin Product Support or seek the assistance of a
professional installer.
Installation Guidelines
To maximize the performance of the radar, please observe the following installation guidelines:
• An ideal scanner mounting location is high above the ship’s keel line with a minimal part of the vessel’s structure or rigging blocking
the radar beam. Obstructions in the path of the radar beam may cause blind and shadow sectors, or generate false echoes. The higher the
installation position, the further the scanner can detect targets.
• Avoid mounting the scanner on the same level as smoke stacks, horizontal spreaders, or crosstrees on a mast. Do not install the scanner
near heat sources where it may be subjected to smoke or hot air from smoke stacks or heat from lights.
• The mounting surface or platform should be sturdy enough to support the weight of the scanner (15.8 lbs/7.17 kg), fl at as possible, and
parallel with the vessel’s water line.
• It is recommended that the radar scanner be mounted out of range of personnel (horizontal beam width above head height). When the
scanner 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 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.
• A “Compass Safe Distance” must be maintained between the compass and the scanner. The Compass Safe Distance is measured from the
center point of the compass to the nearest point on the scanner.
Standard compass = 1 m
Standby Steering and Emergency compasses = 0.6 m
• Mount other electronics and cables more than 2 m (7 ft) from the path of a radar beam. A radar beam can normally be assumed to spread
25° vertically above and below the scanner’s radiating element. For vessels with higher bow angles at cruise speed, it may be helpful to
lower the angle so the beam points slightly downwards to the waterline while at rest. Shims may be used as necessary.
• Install the scanner away from antennas for other electronics. GPS antennas should be either above or below the radar beam path of the
scanner. Mount at least 1 m (3 ft) from any equipment transmitting or cables carrying radio signals, such as VHF radios, cables and
antennas. In the case of SSB radios, the distance should be increased to 2 m (7 ft). IEC 60936-1 clause 3-27.1 states maximum distances
from the antenna at which RF (radio frequency) levels can be expected.
(100W/m squared = 48" [121.92 cm]) (10W/m squared = 108" [274.32 cm])
• The radar scanner transmits electromagnetic energy. It is important that the radar is turned off or the DC power input is disconnected
when personnel are required to come close to the scanner to perform work on the scanner assembly or associated equipment.

GMR 18 Marine Radar Installation Instructions 3
Installation
The following order of mounting the scanner and attaching the Power/Network cables may vary depending on the installation location and
mount used.
Mounting the Scanner
1. When a suitable mounting location has been determined, verify that the mounting hole locations are aligned fore and aft, then drill four
9.5 mm (0.37") mounting holes referencing Figure 1 below. (This step is not necessary if you are using a pre-drilled Garmin compatible
or Raymarine® mount.)
2. Align the notch and locking ring on the power cable to the power connector. Press the 2-pin power cable to the power connector and the
RJ-45 marine network cable to the RJ-45 socket (Figure 2). Turn the power cable locking ring clockwise until it stops. Tighten the RJ-45
locking ring clockwise until it is fi rmly sealed.
3. The power/network cable may be pressed into one of the fi ve guide grooves molded into the bottom of the scanner case and secured
under the cable hold-down plate (Figure 2). Avoid excessive bending or twisting of the cable. See the following “Cable Runs” section for
more information.
4. Position the scanner on the mounting surface with the triangular mark on the case aligned to the front of the vessel. Apply a bead of
marine sealant around each of the mounting holes on the mounting surface.
5. Install the four (4) M8 x 1.25 x 60 threaded rods into the Mounting Holes on the bottom of the scanner. There should be no more than
50 mm (2") extruding from the scanner when they are installed properly.
6. Fasten the scanner to the mounting surface using the M8 x 1.25 x 60 threaded rods (installed in the previous step), spring washers, fl at
washers, and M8 Hex nuts as shown in Figure 3. The nuts should be torqued to between 13.7-18.6 Nm (10-14 lb ft).
NOTE: The supplied M8 x 1.25 x 60 threaded rods can be used on mounting thicknesses of 5-30 mm (1 1/8") (recommended). For surfaces over
30 mm (1 1/8"), locally supplied longer threaded rods are needed.
Cable Runs
Route the cable as needed, depending on the type of mount you are using. DO NOT cut the cable! It may be necessary to drill a 31.7 mm
(1.25") hole for routing the power/network cable. Garmin provides a rubber cable grommet which may be used to cover the cable installation
hole. The grommet does NOT provide a waterproof seal. To waterproof the grommet, apply a marine sealant. Additional cable grommets can be
purchased through Garmin or a Garmin dealer.
When installing the power/network cable, observe the following:
• To ensure safety, use the appropriate tie-wraps, fasteners, and sealant to secure the cable along a route and through any bulkhead or deck.
Avoid running the cable near moving objects, high-heat sources, or through doorways and bilges.
• Avoid installing the cable next to or parallel to other cables, such as radio antenna lines, or power cables. This is essential to avoid
interference to or from other equipment. If this is not possible, shield the cable with metal conduit or a form of EMI shielding.
• Install the power portion of the cable as close to the battery source as possible. A minimum of 10 VDC is required at the 15 m cable
connector during radar turn-on and operation. See the Wire Gauge Table below for the recommended wire gauge between radar cable and
battery.
