SAFETY INSTRUCTIONS

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.

1. MOUNTING

1.1 Antenna Unit

1.1.1 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.

∙No funnel, mast or derrick should be within the vertical beamwidth of the antenna in the bow direction, especially zero degrees ±5°, to prevent blind sectors and false echoes on the radar picture.

∙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.

∙Locate the antenna of a direction finder clear of the antenna unit to prevent interference to the direction finder. A separation of more than two meters is recommended.

∙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 placed too close to the antenna unit. Observe the following compass safe distances to prevent deviation of a magnetic compass: Standard compass, 1.70 m (FR-2115-B), 2.10 m (FR-2125-B), Steering compass, 0.90 m (FR-2115-B), 1.20 m (FR-2125-B).

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

∙The signal cable run between the antenna and the display is available in lengths of 15 m (standard), 20 m, and 30 m. Whatever length is used it must be unbroken; namely, no splicing allowed.

∙The antenna base is made of cast aluminum. To prevent electrolytic corrosion of the antenna base, use the seal washers and corrosion-proof rubber mat.

∙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.

∙Leave sufficient space around the unit for maintenance and servicing. See the antenna unit outline drawing for recommended maintenance space.

1-1

1.1.2 Assembling the antenna unit

The antenna unit consists of the antenna radiator and the antenna unit chassis, and they are packed separately. Fasten the antenna radiator to the antenna unit chassis as follows:

1.For the XN20AF, XN24AF, attach two guide pins to the underside of the antenna radiator.

2.Remove the waveguide cap from the radiator bracket. The cap may be discarded.

3.Coat the waveguide flange with anticorrosive sealant as shown in Figure 1-1.

4.Coat fixing holes for the antenna radiator with anticorrosive sealant.

5.Grease the O-ring and set it to the O-ring groove of the radiator flange.

6.Set the antenna radiator to the radiator bracket.

7.For the XN20AF, XN24AF, coat hex bolts (M8X40, slotted washer-head, 8 pcs.) with anticorrosive sealant and use them to loosely fasten the antenna radiator to the antenna unit chassis. For the XN12AF, coat hex bolts, flat washers and spring washers with anticorrosive sealant and use them to loosely fasten the antenna radiator to the antenna unit chassis.

8.For the XN20AF, XN24AF, remove two guide pins (inserted at step 1).

9.Tighten the bolts loosely fastened at step 7.

CAUTION

Be sure to remove the guide pins.

Injury may result if the guide pins loosen and fall.

1.2 Processor Unit

1.2.1 Mounting considerations

When selecting a mounting location, keep in mind the following points:

∙The processor unit must be mounted horizontally.

∙DO NOT place any item on the top of the processor unit.

∙Locate the unit out of direct sunlight and away from heat sources because of heat that can build up inside the cabinet.

∙Locate the equipment away from places subject to water splash and rain.

∙Be sure the mounting location is strong enough to support the weight of the unit under the continued vibration which is normally experienced on the ship. If necessary reinforce the mounting location.

∙Determine the mounting location considering the length of the following cables:

a)Signal cable from the antenna unit

b)Power cable from the ship's mains

c)Monitor cable from the monitor

d)Control cable from the control unit

∙Leave sufficient space on the sides and rear of the unit to facilitate maintenance. Also, leave a foot or so of "service loop" in cables behind the unit for servicing ease.

∙A magnetic will be adversely affected if placed too close to the processor unit. Observe the following compass safety distances to prevent deviation of a magnetic compass: Standard compass, 1.70 m, Steering compass, 0.90 m.
