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 first to see what is on the other side of the surface. If you experience difficulty with the installation, contact Garmin Product support or seek the assistance of a professional installer. Installation Guidelines In order 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/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 or horizontal spreaders/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/platform should be sturdy enough to support the weight of the scanner (26 lbs), flat as possible, and parallel with the vessel’s water line. at which RF (Radio Frequency) levels can be expected. GMR20 (100W/m squared = 40 cm [15.75"]) (10W/m squared = 120 cm [47.24"]) GMR40 (100W/m squared = 60 cm [23.62"]) (10W/m squared = 175 cm [68.90"]) • It is recommended that the radar scanner be mounted out of range of personnel (horizontial beam width above head height). When the scanner is transmitting, do not look directly at the antenna at close range as your 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 vessel’s 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 e.g. 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 maximum distances from the antenna Ideal Radiation PlaneIdeal Radiation Plane 12.5° 12.5° 12.5° 12.5° • The radar scanner transmits electromagnetic energy. It is important that the radar is turned off or the DC power input is disconnected whenever personnel are required to come close to the scanner to perform work on the scanner assembly or associated equipment. Installation The following order of mounting the scanner and attaching the Power/Network cables may vary depending on the installation location and mount used. GMR 20/40 Radar Installation Manual Mounting the Scanner 1. Once 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. Remove the supplied M8x30 bolts, flat washers, and spring washers (4 each) from the bottom of the scanner unit. Do NOT remove the outer case bolts. There are no user serviceable parts in the scanner and opening the case may void your warranty. 3. 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 firmly sealed. 4. The Power/Network Cable may be pressed into one of the three guide grooves moulded into the bottom of the scanner case (Figure 2). Avoid excessive bending or twisting of the cable. See the following “Cable Runs” section for more information. 5. Position the scanner on the mounting surface with the triangular marks on the case aligned to the front of the vessel and the rounded marks aligned towards aft (Figure 2). A bead of marine sealant may be applied around each o...
