GMR600/1200 Series Radar Installation Instructions

Properly install your GMR 600/1200 series radar according to the following instructions. If you experience difficulty installing the chartplotter, seek the assistance of a professional installer, or contact Garmin® Product Support.

Before installing your GMR 600/1200 series radar, confirm that the package contains the items listed on the box. If any parts are missing, contact your Garmin dealer immediately.

Warning: Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.

Warning: The selected radar mounting location must be able to hold the weight of the radar and withstand any inertial forces.

Warning: The radar 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 radar to perform work on the radar assembly or associated equipment. Electromagnetic energy is harmful.

CAUTION: When the radar is transmitting, do not look directly at the antenna at close range, because the eyes are the most sensitive part of the body to electromagnetic energy.

Notice: When drilling or cutting, always check the opposite side of the drilling or cutting surface.

Selecting a Location

When selecting a location to install the GMR 600/1200 series radar, consider the following:

An ideal mounting location is high above the keel line of the ship with a minimal part of the 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 farther the radar can detect targets.

Avoid mounting on the same level as smoke stacks, horizontal spreaders, or crosstrees on a mast.

Do not install the radar near heat sources where it may be exposed 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 radar and any inertial forces, as flat as possible, and parallel with the water line.

Garmin recommends mounting the radar out of range of personnel (vertical beam width above head height).When properly installed and operated, the use of this radar conforms to the requirements ofANSI/IEEE C95.1-1992 Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields.

IEC 60936-1 clause 3-27.1 states maximum distances from the antenna at which Radio Frequency (RF) levels can be expected.

GMR 604 (100W/m squared = 67 in. [1.7 m]) (10W/m squared = 217 in. [5.5 m])

GMR 606 (100W/m squared = 79 in. [2 m]) (10W/m squared = 244 in. [6.2 m])

GMR 1204 (100W/m squared = 99 in. [2.5 m]) (10W/m squared = 307 in. [7.8 m])

GMR 1206 (100W/m squared = 111 in. [2.8 m]) (10W/m squared = 343 in. [8.7 m])

Caution: When the radar is transmitting, do not look directly at the antenna at close range (the eyes are the most sensitive part of the body to electromagnetic energy).

Acompass safe distance must be maintained between the compass and the radar.The compass safe distance is measured from the center point of the compass to the nearest point on the radar.

Standard compass = 35 7/16 in. (90 cm)

Standby Steering and Emergency compasses = 31 1/2 in. (80 cm)

Mount other electronics and cables more than 7 ft. (2 m) from the path of a radar beam.Aradar beam can spread 25° vertically above and below the radiating element of the radar. For vessels with higher bow angles at cruise speed, you can lower the angle so that the beam points slightly downward to the waterline while at rest. Shims may be used as necessary.

12.5°

12.5°

Install the radar away from antennas or other electronics. GPS antennas should be located above or below the radar beam path of the radar. Mount at least 3 ft. (1 m) from any equipment transmitting or cables carrying radio signals, such asVHF radios, cables, and antennas. In the case of SSB radios, the distance should be increased to 7 ft. (2 m).

 

GMR 600/1200 Series Installation Instructions

Installing the Mounting Studs and Seals

1.Remove the hatch on the front of pedestal by loosening the screw and lifting the hatch off of the hinges as shown in Figure 1.

2.Use a 5 mm Allen wrench, to install the M10 x 71 mounting studs (Figure 2) in the pedestal matching the hole pattern that was selected. Tighten the mounting studs until they bottom out in the pedestal. Do not overtighten the studs to avoid damaging the pedestal. The mounting studs have a thread-locking patch applied at the factory.

Optional: Apply moisture-inhibitive grease or paste to the four studs prior to installation.

3.Install the seals onto the pedestal (Figure 3).

Mounting the Radar

Mount the radar with either end pointed toward the bow. Ensure it is mounted along the Bow-SternAxis line indicated on the GMR 400/600/1200 Series Mounting Template. If the end with the hatch is pointed toward the bow, the Front of Boat Offset setting on the chartplotter must be set to 180° (Figure 4).To adjust the Front of Boat Offset on the chartplotter, see page 7.

To mount the radar:

1.(Skip to step two if you are using a pre-drilled Garmin compatible Furuno® or Raymarine® mount.) Determine a suitable mounting location and tape the Mounting Template in place. The Mounting Template has two hole patterns: Option A and Option B. Determine the most appropriate patterns from the two patterns available on the Mounting Template (Option A or Option B). Use a 1/2 in. (13 mm) bit to drill the four mounting holes.

2.Hoist the radar into position using the supplied strap. Position the strap over the ends of the antenna mount as shown in Figure 5. Ensure that you position the strap as close to the radar as possible.

3.Fasten the radar to the mounting surface using the M10 hex nuts, spring washers, and flat washers in the order shown in Figure 6. The M10 nuts should be torqued to 130 lbf-in (11 lbf-ft) (1.5 kgf-m).

Installing the Power and Network Cables

Route the cable as needed, based on the type of mount you are using.

When installing the power and network cables, consider 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.

You may need to drill a 1 1/4 in. (31.7 mm) hole for routing the power/network cable. Garmin provides a rubber cable grommet to cover the cable installation hole.

The grommet does NOTprovide a waterproof seal.To waterproof the grommet, apply a marine sealant.

You can purchase additional cable grommets through Garmin or a Garmin dealer.

Use the optional field-installable RJ-45 network connector (included) to create a custom-length Garmin Marine Network cable if needed (see page 8).
