1. MOUNTING
1.1 Mounting Methods for
Scanner Unit
• 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 allround view. Any obstruction will cause
shadow and blind sectors. A mast for instance, with a diameter considerably less
than the width of the radiator, will cause
only a small blind sector, but a horizontal
spreader or crosstrees in the same horizontal plane as the scanner unit would be
a much more serious obstruction; you
would need to place the scanner unit well
above or below it.
• 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.
• If you have a radio direction finder on your
boat, locate its antenna 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, 1.00 m,
Steering compass, 0.75 m.
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
• When this radar is to be installed on larger
vessels, consider the following points:
• The signal cable run between the scanner and the display comes in lengths
of 10 m (standard), 15 m, 20 m and 30
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.
As shown in the figure below, the scanner
unit may be installed on the bridge, on a common mast or on the radar mast.

(b) Common mast
(c) Radar mast
Figure 1-1 Scanner unit mounting methods
1.2 Fixing Holes in Mounting
Platform
Referring to the outline drawing on page D1, drill five holes in the mounting platform:
four holes of 15 mm diameter for fixing the
scanner unit and one hole of 25-30 mm diameter for the signal cable.

When selecting a mounting location for the
display unit keep in mind the following points:
• Provide adequate space behind and
around the unit to permit circulation of air
and to provide convenient access to the
rear connection.
• Even though the picture is quite legible
even in bright sunlight, keep the display
unit out of direct sunlight or at least shaded
because of heat that can build up inside
the cabinet.
• Locate the display unit in a position where
you can view and operate it conveniently
but where there is no danger of salt or
fresh water spray or immersion.
• The orientation of the display unit should
be so the radar screen is viewed while the
operator is facing in the direction of the
bow. This makes determination of your
position much easier.
• Make sure you allow enough clearance
both to get to the connectors behind the
unit and to allow you to get your hands in
on both sides to loosen or tighten the
mounting knobs. Make sure you leave at
least a foot or so of “service loop” of cables
behind the unit so it can be pulled forward
for servicing or easy removal of the connectors.
• The compass safe distance of 0.75 meters
(standard compass) and 0.6 meters (steering compass) should be observed to prevent deviation of the magnetic compass.
• Even though the display unit meets waterproof standard IPX-5, the connection of
external buzzer, radar plotter and/or remote display can affect waterproofness.
Watertight integrity cannot be guaranteed.
When these modification has been done,
the display unit should not be mounted
where exposed.
Mounting
The display unit is designed to be mounted
on a tabletop or bulkhead.
1. Using the hanger as a template, mark
screw locations in the mounting location.
2. Fix the hanger to the mounting location
with five M6 tapping screws (supplied).
3. Fit the knob bolts to the display unit. Install the display unit in the hanger. Tighten
the knob bolts securely.
2. CONNECTIONS
2.1 Connecting the Signal
Cable
Only the signal cable runs from the display
unit to the scanner unit. In order to minimize
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. Pass the cable
through the hole and apply sealing compound
around the hole for waterproofing.
3. Unfasten the cable gland assembly (plate,
gasket, flat washer).
4. Pass the signal cable w/connector
through the bottom of the scanner unit
chassis. Pass the cable through the gland
assembly as shown below.
1. Open the scanner cover by loosening two
screws, and then fix the stay.

by using the omnipad, and press [ACQ/
ENTER] key.
3. Select “24. Installation Setup”.
Before transmitting the radar make sure
no one is near the scanner unit, to prevent the potential risk of being struck
by the rotating scanner and exposure
to RF radiation hazard.
2. On the Installation Setup menu, select “8.

3.4 Aligning Heading
(Adjustment sector: 0~359.90)
You have mounted the scanner unit facing
straight ahead in the direction of the bow.
Therefore, a small but conspicuous target
dead ahead visually should appear on the
heading marker (zero degrees).
In practice, you will probably observe some
small bearing error on the display because
of the difficulty in achieving accurate initial
positioning of the scanner unit. The following
adjustment will compensate for this error.
1. Identify a suitable target (for example, ship
or buoy) at a range between 0.125 to 0.25
nautical miles, preferably near the heading marker. To lessen error, keep echoes
in the outer half of the picture by changing the range. Also, be sure the zoom and
off center functions are off.
2. Select “9. Heading Alignment” from the
Installation Setup menu and press the
[ACQ/ENTER] key. The following message appears:
[Heading Alignment]
Set EBL1 to center of target
dead ahead and press ENTER.

3.5 Adjusting Sweep Timing
(Adjustment range: 0.000~4.266 nm)
This adjustment ensures proper radar performance, especially on short ranges. The
radar measures the time required for a transmitted echo to travel to the target and return
to the source. The received echo appears on
the display based on this time. Thus, at the
instant the transmitter is fired, the sweep
should start from the center of the display
(sometimes called sweep origin).
A trigger pulse generated in the display unit
goes to the scanner unit through the signal
cable to trigger the transmitter (magnetron).
The time taken by the signal to travel up to
the scanner unit varies, depending largely on
the length of the signal cable. During this period the display unit should wait before starting the sweep. When the display unit is not
adjusted correctly, the echoes from a straight
local object (for example, a harbor wall or
straight pier) will not appear with straight
edges – they will be seen as “pushed out” or
“pulled in” near the picture center. The range
of objects will also be incorrectly shown.

3. Operate the omnipad to bisect target selected at step 1 with the heading marker.
4. Press the [ACQ/ENTER] key.
5. As a final test, move the boat towards a
small buoy and confirm that the buoy
shows up dead ahead on the radar when
it is visually dead ahead.

3.8 Setting a Dead Sector
3.6 Adjusting MBS
(Adjustment range: 0.00~0.25)
Main bang, a large filled circle which appears
at the display center on short ranges, can be
suppressed as follows:
1. Transmit on long range about 10 minutes.
When the scanner is installed at a close distance in front of the wheelhouse, the radar
should be set not to transmit within that area,
to prevent microwave hazard. The dead sector area graphic can be turned on/off on the
OTHERS menu.
2. Adjust the gain to show a small amount
of noise on the display.
1. Select “7. Dead Sector” from the Installation Setup menu and press the [ACQ/ENTER] key.
3. Change to the 0.125 nautical mile range
and adjust the [A/C SEA] control.
2. Operate the omnipad to enter starting
