GMR 18 Marine Radar Installation Instructions

Installation

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 Garmin MFDs (multi-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 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

To maximize the performance of the radar, 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), flat 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 (39.37")

Standby Steering and Emergency compasses = 0.5 m (19.7")

•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 downward 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.
