WARNING

Radio Frequency

Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the antenna aperture from a close distance while the radar is in operation or expose yourself to the transmitting antenna at a close distance.

Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below.

Note: If the antenna unit is installed at a close distance in front of the wheel house, your administration may require halt of transmission within a certain sector of antenna revolution. This is possible - Ask your FURUNO representative or dealer to provide this feature.

SYSTEM CONFIGURATIONS

All NavNet products incorporate a "network circuit board" to integrate each NavNet product on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is assigned an IP address to enable transfer of images between other NavNet products. For example, video plotter pictures can be transferred to a radar and vice versa. Pictures received via the NavNet may be adjusted at the receiving end.

The number of processor units which may be installed depends on the number of network sounders connected. For a system incorporating three or more NavNet products, a "hub" is required to process data.

For one network sounder: one radar and three plotters, or four plotters For two network sounders: one radar and two plotters, or four plotters

1. MOUNTING

NOTICE

Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts of the equipment.

Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors.

1.1 Mounting the Control Unit

1.1.1 Mounting considerations

The control unit can be mounted on a desktop or flush mounted in a console or panel. For flush mounting, the optional flush mount kit is required.

When selecting a mounting location for the control unit keep the following in mind:

Keep the control unit out of direct sunlight.

The temperature and humidity at the mounting location should be moderate and stable.

Locate the unit away from exhaust pipes and vents.

The mounting location should be well ventilated.

Mount the unit where shock and vibration are minimal.

Keep the unit away from electromagnetic field generating equipment such as motors and generators.

For maintenance and checking purposes, leave sufficient space at the sides and rear of the unit and leave slack in cables. Minimum recommended space is shown in the outline drawing for the control unit.

A magnetic compass will be affected if the control unit is placed too close to it. Observe the compass safe distances shown in the SAFETY INSTRUCTIONS to prevent disturbance to the magnetic compass.

1.2 Mounting the Processor Unit

The unit can be mounted on the deck, a desktop or on a bulkhead. Select a mounting location considering the points below.

Locate the unit out of direct sunlight.

Select a location where temperature and humidity are moderate and stable.

Consider the length of the cable connected among the processor unit, antenna unit (or power supply unit) and control unit.

For mounting on a bulkhead, be sure the mounting location is strong enough to support the unit (4.1kg) under the pitching and rolling normally encountered on the vessel.

Leave sufficient space around the unit for maintenance and servicing. Recommended maintenance space appears in the outline drawing at the back of this manual.

A magnetic compass will be affected if the processor unit is placed too close to the magnetic compass. Observe the compass safe distances in the SAFETY INSTRUCTIONS to prevent disturbance to the magnetic compass.

Tabletop or deck mounting: Fasten with four tapping screws.

Bulkhead mounting: Mark four fixing hole positions on the bulkhead. Screw in two tapping screws at lower fixing positions, leaving 5 mm protruding. Set the processor unit to the screws and screw in two tapping screws at upper positions. Tighten all screws.

1.3 Mounting the Antenna Unit of MODEL1824C-BB

1.3.1 Mounting considerations

When selecting a mounting location for the antenna unit, keep in mind the following points.

Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate platform. (For sailboats, a mounting bracket is optionally available.) It should be placed where there is a good all-round view with, as far as possible, no part of the ship’s superstructure or rigging intercepting the scanning beam. Any obstruction will cause shadow and blind sectors. A mast, for instance, with a diameter considerably less than the width of the antenna unit, will cause only a small blind sector. However, a horizontal spreader or crosstrees in the same horizontal plane would be a much more serious obstruction; place the antenna unit well above or below it.

In order to minimize the chance of picking up electrical interference, avoid where possible routing the antenna cable near other electrical equipment onboard. Also avoid running the cable in parallel with power cables.

Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS to prevent interference to a magnetic compass.

2.Construct a platform (wood, steel*, or aluminum) of 5-10 mm (recommended dimension) in thickness referring to the outline drawing at back of this manual. Fasten the platform to the mounting location. Next, position the mounting base on the platform so the cable entrance faces the stern direction.

*: For steel platform take appropriate measures to prevent corrosion.

Note: When drilling holes in the platform, be sure they are parallel with the fore and aft line.

3.Using the hex bolts, flat washers and spring washers removed at step 1, fasten the mounting base to the platform. The torque should be between 19.6-24.5 Nm.

Note: Longer hex bolts (M10X25) are supplied with the installation materials. Use them instead of the hex bolts removed earlier if the mounting platform thickness is 5–10 mm.

1.5Mounting the Antenna Unit of MODEL1934C-BB/1944C-BB/1954C-BB/1964C-BB

1.5.1 Mounting considerations

The antenna unit is generally installed either on top of the wheelhouse or on the radar mast on a suitable platform. Locate the antenna unit where there is a good all-round view. Any obstruction will cause shadow and blind sectors. A mast for instance, with a diameter considerably less than the horizontal beamwidth of the radiator, will cause only a small blind sector, but a horizontal spreader or crosstrees in the same horizontal plane as the antenna unit would be a much more serious obstruction; you would need to place the antenna unit well above or below it.

It is rarely possible to place the antenna unit where a completely clear view in all directions is available. Thus, you should determine the angular width and relative bearing of any shadow sectors for their influence on the radar at the first opportunity after fitting.

To lessen the chance of picking up electrical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also avoid running the cable in parallel with power cables.

A magnetic compass will be affected if the antenna unit is placed too close to it. Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS to prevent interference to a magnetic compass.

Do not paint the radiator aperture, to ensure proper emission of the radar waves.

When this radar is to be installed on larger vessels, consider the following points:

The signal cable run between the antenna and the display units comes in lengths of 10 m, 15 m, 20 m and 30 m.

Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial performance and hot gases may distort the radiator portion. The antenna unit must not be mounted where the temperature is more than 70°C.

As shown in the figure below, the antenna unit may be installed on the bridge, on a common mast or on the radar mast.
