The radar scanner emits electromagnetic
radio frequency (RF) energy which can be
harmful, particularly to your eyes. Never
look directly into the scanner aperture from
a close distance while the radar is in operation or expose yourself to the transmitting
scanner at a close distance.
Distances at which RF radiation levels of
100 and 10 W/m

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

•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.
•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, 4.8 m, Steering compass, 3.6 m.
•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, 30 m and 60 m. Whatever length is used it must be unbroken;
namely, no splicing allowed.
•Deposits and fumes from a funnel or other exhaust vent can adversely af fect 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.
•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).
•Leave suf ficient space around the unit for maintenance and servicing. See the scanner
unit outline drawing for recommended maintenance space.

Installation precaution for S-band scanner unit
If an S-band scanner unit is mounted near the end of a platform to provide sufficient
rotation clearance for the radiator, the scanner unit, because of its weight, swings up and
down by ship’s vibration and rolling, exerting excessive levels of stress at the base of the
radiator, which can damage the radiator. To prevent this, relocate the scanner unit, or if
relocation is not possible, reinforce the platform.

Scanner unit assembling
The scanner radiator and the scanner housing are shipped in separate packages and
must be assembled at installation. Assemble them as below.
The scanner unit may be assembled before hoisting it to the mounting platform. However,
do not lift the scanner unit by the radiator.
1. Remove two protective caps from the radiator flange and rotary joint flange.
2. Grease an O-ring and place it in the groove of the rotary joint flange. Make sure the
O-ring is not pinched during assembling.
3. Secure the feeder waveguide to the rotary joint flange with four M6x16 hex bolts.
4. Fix the feeder waveguide on the radiator bracket with a waveguide clamp, a clamp
insulator, two flat washers, and two M6x50 hex bolts.
5. Grease other O-ring and set it in the groove of the radiator flange.
6. Set the scanner radiator to the bracket and fix it temporarily with eight M10x20 hex
bolts, spring washers and flat washers.
7. Fasten the feeder waveguide to the radiator flange with four M6x16 hex bolls.
8. Fasten the scanner radiator to the bracket with eight M10x20 bolts.

Mounting the scanner unit
1. Referring to the scanner outline drawing, drill four bolt holes (15 mm dia.) in the radar
mast platform or the deck.
2. Place the corrosion-proof rubber mat (supplied) on the mounting platform.
3. Using the two L-angle metal plates on the scanner top, lift the scanner base with the
antenna radiator and place the scanner unit on the rubber mat. Orient the scanner so
its cable glands face the ship’s stern.

ers and seal washers (supplied).
5. Arrange the grounding terminal at the nearest grounding spot with the M6x25 hex bolt,
nut and washers (supplied). Then, fix a ground wire (RW-4747, 340 mm) to the terminal.
6. Connect the other end of the ground wire to the ground terminal of the scanner unit.

1.2 Display Unit
Mounting considerations
When selecting a mounting location, keep in mind the following points:
•Select a location where the display unit can be viewed and operated conveniently and
where the screen can be viewed while facing towards the bow.
•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 signal cable between the
scanner unit and the display unit. (The signal cable comes in lengths of 15, 20, 30 or 60
meters; maximum 100 meters).
•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 so it can be pulled forward
for servicing or easy removal of connectors.
•A magnetic compass will be affected if placed too close to the display unit. Observe the
following compass safe distances to prevent deviation of a magnetic compass: Standard compass, 1.15 m, Steering compass, 0.90 m.
Mounting procedure
1. Loosen the two screws at the front of the display unit.
Screw
Figure 1-5 Display unit, front view

2. Lift the front panel.
Bolt
Figure 1-6 Display unit, cover opened
3. Unfasten two bolts (M8 x 40) at the bottom front of the display unit, and then remove
the mounting base.
4. Mark screw locations in the tabletop, using the mounting base as a template. For mount-
ing by bolts, nuts and washers, drill four holes of 12 mm diameter in the tabletop.
5. Fasten the mounting base to the tabletop by tapping screws, or M10, bolts, nuts and
washers.
6. Lay the display unit on the mounting base. Fasten the display unit to the mounting
base with the two M8 x 40 bolts removed at step 3.
7. Close the cover and fasten it.
Optional handles
Handles are available. Detach the caps attached to the display unit and fasten the handles.
1.3 Power Supply Unit
The Power Supply Unit PSU-002 does not contain usual operating controls. Therefore,
they can be installed in any recessed place either in vertical or horizontal position. However, select a dry and well-ventilated location and observe the compass safe distances
below to prevent deviation of a magnetic compass.

2.1 Scanner Unit
Two signal cables are terminated at the scanner unit: signal cables S03-78 and
660V-MPYCY-16 (from the power supply unit).
Preparations
Open the port side cover (six bolts) of the scanner unit. Unfasten fixing plates to access
terminal boards.
Signal cable S03-78 (JIS cable)
1. Shorten the cable, extending the length actually required by 600 mm. Strip off about
600 mm of the anti-corrosive vinyl sheath and 590 mm of the armor and the inner vinyl
sheath, being careful not to nick the braided shield.

6. Ground the armor through the two washers as shown above. Trim the shields con-
sidering their location on the earth terminal inside the scanner unit. Fit a crimp-on lug
(yellow, FV5.5-4, ø4) to inner and outer shields, then connect them to the ground terminal inside the scanner unit.
7. Determine the length of each core considering its location on STB-1 in the scanner unit
(see the interconnection diagram on page S-1). Remove approx. 6 mm of the vinyl
insulation from the end of each core and fix the crimp-on lug FV1.25-M3 (Red) to each
core.
8. Remove the outer sheath of the coaxial cable (2C-2V) by 75 mm. Pull back the braided
shield to expose the inner core. Remove approx. 25 mm of insulator from the end of
inner core and fold back conductor as illustrated below. Shorten the shield leaving
approx. 45 mm. Fit crimp-on lugs to the conductor (FVD1.25-3, Red) and braided shield
(FV1.25-M3, Red).
