1. MOUNTING
1.1 Scanner Unit
Mounting considerations
• The scanner unit is generally installed either on top of the wheelhouse or on the radar mast,
on a suitable platform. Locate the scanner unit where there is a good all-round view.
(a) On bridge (b) Common mast (c) Radar mast
Figure 1-1 Mounting methods
• No funnel, mast or derrick should be within the vertical beamwidth of the scanner 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 scanner 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 scanner 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 scanner unit. Observe the
following compass safe distances to prevent deviation of a magnetic compass: Standard
compass,1.70 m (FR-2815), 2.10 m (FR-2825), Steering compass, 1.90 m (FR-2815), 1.20
m (FR-2825).
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
• The signal cable run between the scanner 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 scanner base is made of cast aluminum. To prevent electrolytic corrosion of the scanner
base, use the seal washers and corrosion-proof rubber mat and ground the unit with the
ground wire (supplied).
• 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 scanner 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 scanner unit
outline drawing for recommended maintenance space.
1-1
Assembling the scanner unit
CAUTION
The scanner unit consists of the scanner radiator and the scanner unit chassis, and they are
packed separately. Fasten the scanner radiator to the scanner unit chassis as follows:
1) For the XN20AF, XN24AF, attach two guide pins to the underside of the scanner 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 1-2.

7) For the XN20AF, XN24AF, coat hex bolts (M8 x 40, slotted washer head, 8pcs.) with
anticorrosive sealant and use them to loosely fasten the scanner radiator to the scanner unit
chassis. For the XN12AF, coat hex bolts, flat washers and spring washers with anticorrosive sealant and use them to loosely fasten the scanner radiator to the scanner unit chassis.
8) Remove two guide pins (inserted at step 1), and then tighten fixing bolts.
CAUTION
Be sure to remove the guide pins.
Injury may result if the guide pins loosen
and fall.

The scanner unit may be assembled before hoisting it to the mounting platform. However, do
not lift the scanner 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
scanner housing.
CAUTION
DO NOT lift the antenna unit by the radiator;
lift it by the hoist rings. (Be sure to remove
rings after hoisting the antenna unit.)

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.
NO!
3) Lay the rubber mat (supplied) on the mounting platform.

and seal washers.
6) Using hex bolt (M6x25), nut (M6) and flat washer (M6) establish the ground system on the
mounting platform as shown in Figure 1-5. The location should be within 370 mm of the
ground terminal on the scanner unit. Connect the ground wire (RW-4747, 370 mm, supplied) between the grounding point and ground terminal on the scanner unit. Coat the entire
ground system with silicone sealant (supplied).

1.2 Mounting the Display Unit
The display unit is designed to be mounted on a tabletop or on a pedestal (option).
Before mounting the display unit
If Gyro Converter GC-8 (option) is to be used, install and setup the GYRO PROCESSOR
Board before mounting the display unit, because of the difficulty involved if done after the unit
is mounted. Instructions for installation and setup are in Chapter 4.
Siting considerations
Locate the display unit on the bridge in a place where it can be viewed and operated conveniently. In addition, consider the points noted in the figure which follows.
CAUTION
A magnetic compass will be affected if
placed too close to the display unit.
The minimum compass safe distances
for magnetic compasses are
standard compass:1.6 m
steering compass: 1.2 m
Consider the points mentioned below
when selecting a mounting location for the
display unit.
•
The orientation of the display unit should
be so the operator views the screen while
facing the bow. This makes determination
of position much easier.
• The location should be free of water spray.
• The daylight bright type radar display
provides excellent visibility even in direct
sunlight. However, locate the unit out of
direct sunlight and away from heat sources
because of heat that can build up inside
the cabinet.
• The mounting location should be deter mined considering the length of the signal
cable between the antenna unit and the
display unit. (The signal cable comes in
lengths of 15, 20 or 30 meters; maximum
100 meters.)
• Leave sufficient space around the unit for
maintenance and servicing. See the display
unit outline drawing for recommended
maintenance space.

Procedure
1) Turn on the power. Press [RADAR MENU] [0] [0] [2] [2] to select HD ALIGN on the
INITIAL SETTING 1 menu.
2) Select a target echo (by gyrocompass, for example) at a range between 0.125 and 0.25nm,
preferably near the heading mark.
3) Operate the EBL control to bisect the target echo. (The value shown on the display is an-
tenna position in relation to ship's bow.)
4) Press [ENTER] to finish.
3.3 Adjusting Sweep T iming
Sweep timing differs with respect to the length of the signal cable between the antenna unit and
the display unit. Adjust sweep timing at installation to prevent the following symptoms:
• The echo of a "straight" target (for example, pier), on the 0.25nm range, will appear on the
display as being pulled inward or pushed outward. See Figure 3-3.
• The range of target echoes will also be incorrectly shown.
Correct Target pushed Target pushed
inward outward
3–2
Figure 3-3 Examples of correct
and incorrect sweep timings
Procedure
1) Turn on the power . Press [RADAR MENU] [0] [0] [2] [3] to select TIMING ADJ on the
INITIAL SETTING 4 menu.
2) Transmit on the 0.25nm range.
3) Adjust radar picture controls to display picture properly.
4) Select a target echo which should be displayed straightly.
5) Adjust the VRM control to straighten the target echo.
6) Press the [ENTER] key.
3.4 Adjusting Video Signal Level
When the signal cable is very long, the video amplifier input level decreases, shrinking target
echoes. To prevent this, confirm (and adjust if necessary) video amplifier input level.
Procedure
1) Connect an oscilloscope to TP3 on the INT Board (INT-9170).
2) Transmit on the 12nm range. Take trigger at TP10 on the same board.
3) Adjust VR1 on the INT Board so the value of TP3 is 4Vpp. (For secondary display, adjust
VR2 for same level.)
