Caution: Service and maintenance This product contains no user serviceable components. Please refer all maintenance and repair to authorized Raymarine dealers. Unauthorized repair may affect your warranty. Transmitted power density levels • A power density level of 10 W/m is likely at distances of 34 cm or less from the radar scanner. •...
– More than 2 m (6.6 ft) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. • The product is supplied from a separate battery from that used for engine start. This is important to prevent erratic behavior and data loss which can occur if the engine start does not have a separate battery.
Warranty registration To register your Raymarine product ownership, please visit www.raymarine.com and register online. It is important that you register your product to receive full warranty benefits. Your unit package includes a bar code label indicating the serial number of the unit.

3.1 Parts Supplied Check that you have been supplied with the following parts: Drill 4 holes, 10 mm diameter (18'' and 24'' Radomes) Center Line of Radome 233 mm Forward 18'' or 24'' Radome Mounting Template 3026-136-C Artwork Number 3032-866-B...
5.1 Antenna Position The optimum height for the HD Digital Radome Antenna (the antenna) is a location that is high enough above the waterline to give a long range line-of-sight to the horizon, but not so high as to be adversely affected by the boat's pitching and rolling.

Planing hull vessels, and some displacement hull vessels, adopt a higher bow angle when the vessel is at cruising speed. This may raise the radar’s main radiation angle, and can cause poor detection of nearby targets. It may be necessary to compensate for the bow rise to ensure optimum target detection.
5.2 Compass safe distance To prevent potential interference with the vessel's magnetic compasses, ensure an adequate distance is maintained from the product. When choosing a suitable location for the product you should aim to maintain the maximum possible distance from any compasses. Typically this distance should be at least 1 m (3.3 ft) in all directions. However for some smaller vessels it may not be possible to locate the product this far away from a compass.
6.1 Direct connection to RayNet display You need a digital cable, to connect both power and data to the HD Digital Radome Antenna. Depending on your product variant, it may or may not be supplied with a digital cable. For information on suitable cables, refer to: p.44 —...
6.2 Connection to networked RayNet displays You need a digital cable, to connect both power and data to the HD Digital Radome Antenna. Depending on your product variant, it may or may not be supplied with a digital cable. For information on suitable cables, refer to: p.44 —...

• Mounting the antenna. • Connecting to your system. • Post installation procedures. Caution: Mounting Bolts Do NOT screw the antenna mounting bolts into the antenna base more than 25 mm (1 inch), or damage to the antenna could occur. If necessary, use shims or extra washers to prevent this happening.
Mounting the Antenna Use a mounting location that: • Is robust enough to support the HD Digital Radome Antenna, under seagoing conditions. Antenna Position • Meets the requirements described under Then: 1. Prepare the mounting platform as in the following illustration.
Page 37
2. Place the HD Digital Radome Antenna in position. If you are fitting it on a planing vessel, shim the rear of the antenna, so that the beam points slightly down in the forward direction when the boat is at rest, to compensate for the bow rising at cruising speed 3.
Page 38
4. Ensuring that the bolts do not enter the antenna base more than 25 mm (1 inch), secure the antenna with the 4 bolts flat washers and spring washers provided, as illustrated. If necessary, use appropriate shims or extra washers to limit the length of bolt entering the antenna base. 5.
9.1 General cabling guidance Cable types and length It is important to use cables of the appropriate type and length. • Unless otherwise stated only use cables supplied by Raymarine. • Where it is necessary to use non-Raymarine cables, ensure that they are of correct quality and gauge for their intended purpose.
Making connections Follow the steps below to connect the cable(s) to your product. 1. Ensure that the vessel's power supply is switched off. 2. Ensure that the device being connected to the unit has been installed in accordance with the installation instructions supplied with that device.

Bonded ground system (preferred) RF ground system (alternative) Power cable to product. 2. Drain (screen). 3. Bonded (preferred) or non-bonded RF ground. 4. Power supply or battery. Implementation If several items require grounding, they may first be connected to a single local point (e.g. within a switch panel), with this point connected via a single, appropriately-rated conductor, to the boat’s common ground.
• NMEA 0400 Connection procedure Connect the power cable part of the digital cable to either a 12 V or 24 V dc supply, as follows: 1. Red wire to the supply +ve, either at the output of the battery isolator switch or at a dc distribution panel.
Cables You need a digital cable, to connect both power and data to the HD Digital Radome Antenna. Depending on your product variant, it may or may not be supplied with a digital cable. There are 2 main types of digital cable — SeaTalkhs and RayNet. The correct cable for your system depends on the type of multi-function display you are connecting the radome to: Connection via RayNet Connection via SeaTalkhs...
