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.
• 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.
MOUNTING
• T o 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, 2.15 m, Steering compass, 1.60 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 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.
• 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 sufficient 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.

1.2 Display Unit
Before mounting the display unit
If Gyro Converter GC-8 (option) is to be used, install and setup the GYRO CONVERTER Board before mounting the display unit, because of the difficulty involved
in doing it after the display unit is installed. Instructions for installation and setup
are in Chapter 4.
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.
• The display unit is very heavy. 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 and the power supply cable between the display unit and the Power Supply Unit PSU-004.
• 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, 1.70 m, Steering compass, 0.90 m.

6. Ground the armor through the two washers as shown above. Trim the shields
considering 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 (FVD1.253, Red) and braided shield (FV1.25-M3, Red).
