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/m
2
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.

1-2
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.

1.1.3 Fastening the antenna unit to the mounting platform
The antenna unit may be assembled before hoisting it to the mounting platform. However, do
not lift the antenna unit by the radiator. Always hold the unit by its housing. When using a crane
or hoist, lift the unit by the hoist rings which should be fastened to the bolt fixing covers of the
antenna housing.
CAUTION
DO NOT hoist the antenna unit by the
radiator; hoist it by the hoist rings. (Be sure to
remove rings after hoisting the antenna unit.)
Hoist
ring NO!
1. Construct a suitable mounting platform referring to the outline drawing at the back of the
manual.
2. Drill four mounting holes of 15 mm diameter and one cable entry hole of about 50 mm
diameter in the mounting platform.
3. Lay the rubber mat (supplied) on the mounting platform.
4. Place the antenna unit on the rubber mat orienting the unit so the bow mark on its base is
facing the ship's bow.

5. Fasten the antenna unit to the mounting platform with four sets of M12X60 hex bolts, nuts,
flat washers and seal washers (supplied).
6. Using hex bolt (M6X25), nut (M6) and flat washer (M6), establish the ground system on the
mounting platform as shown in Figure 1-4. The location should be within 370 mm of the
ground terminal on the antenna unit. Connect the ground wire (RW-4747, 370 mm, supplied)
between the grounding point and ground terminal on the antenna unit. Coat the entire
ground system with silicone sealant (supplied).
