HIGH VOLTAGE WARNING
Dangerously high voltages are present within the RADAR scanner unit. There are
no internal connections or adjustments necessary for installation. Only a qualified
radar service technician should remove the cover. Technicians must exercise ex-
treme care when working inside the unit. Always remove power before removing
the cover. Some capacitors may take several minutes to discharge, even after
switching off the radar. Before touching the magnetron or any high voltage com-
ponents, ground them with a clip lead.
MICROWAVE RADIATION HAZARD
The microwave energy radiated by a radar antenna is harmful to humans, espe-
cially to one’s eyes. Never look directly into an open waveguide or into the path of
radiation from an enclosed antenna. Radar and other radio frequency radiation
can upset cardiac pacemakers. If someone with a cardiac pacemaker suspects
abnormal operation, immediately turn off the equipment and move the person
away from the antenna. Turn off the radar whenever it is necessary to work on
the antenna unit or on other equipment in the beam of the radar.
MAGNETRON PREHEATING
When starting your RADAR for the first time or when restarting it after a two
month or longer non-operating period, preheat the magnetron at least 30 min-
utes in standby mode.
Please read through this manual before the first operation. If you have any ques-
tions, please contact the Company’s customer service or your local dealer.

User Manual
1. Radar Installation
This chapters illustrates the instructions on electrical connections of the Radar
and the necessary software settings to operate it.
WARNING
In order for the Radar to communicate with the Chart Plotter, the software
configuration explained in the Par. 1.5 is mandatory.
1.1 PRELIMINARY
The scanner unit must be located so that passengers and crew are not exposed to
the direct radar beam. The scanner unit should be mounted on the centerline of
your vessel in a location that has an unobstructed view forward and is as clear as
possible the rest of the way around the unit. A location as high as practical to
improve maximum range is preferable, keeping in mind that minimum range ob-
jects may be overlooked if mounted too high. Place the units in before large
structures and exhaust stacks. Large structure or stacks cause blind spots. Con-
tamination from engine exhaust on the scanner housing reduces radar perfor-
mance.
Antennas for GPS, radio communication or other equipment should not be in the
radar beam. Use non-metallic extension poles to move the active area of anten-
nas above the radar beam.
In selecting a location, consider the suitability of the mounting surface. It must be
flat and approximately levelled with the vessel’s water line. The surface must
support the weight of the scanner and have access to the under side for installa-
tion of the four mounting bolts.
NOTE The recommended mounting surface thickness is 3/8 to 1/2 in. (9 mm to 13 mm).
The scanner will be damaged if bolts penetrate more than 9/16 in. (15 mm).
Also, consider the cable route from the scanner to the operator’s location. Avoid
routing the interconnecting cable through areas of possible damage from moving
objects, machinery, and exposure to chemicals or high temperature.
1.2 PREPARATION
Unpack your new RADAR and check that the contents correspond to the packing
list. Do not remove the cover from the unit. There are no connections or adjust-
ments inside the unit that are needed for installation or operation. The cable must
remain attached. For ease of handling, coil the cable and place it on top of the
scanner. Then secure it with tape. Invert the scanner and make sure the four
mounting holes are clear to accept bolts.
Working at higher elevations may become necessary while installing the scanner
unit. Observe safety measures and take sufficient precaution to avoid personal
injury or damage to the equipment.
1.3 PROCEDURE
♦Prepare the mounting surface by making sure it is clean and flat.
♦Use the template provided to mark the location of four mounting holes.
Align the template squarely with the centerline of the vessel and with
the arrow pointing forward.

10 User Manual
♦Drill four 3/8 in. (10 mm) diameter holes through the mounting sur-
face.
♦Check that each bolt (with lock washer and flat washer) protrude through
the mounting surface at least 5/16 in. (8 mm) but less than 9/16 in.
(15 mm). The scanner will be damaged if bolts protrude more than 9/
16 in. (15 mm).
♦Apply sealant around each mounting hole.
♦Place the Radar scanner unit on the mounting surface. Orient the scan-
ner with the index mark on the housing facing forward (cable gland
facing aft).
♦Install and tighten four M8 x 25U (M8 x 1 in.) mounting bolts.
♦Uncoil the scanner cable.
♦Secure the cable near the scanner to support the weight of the cable
and prevent strain on the watertight cable seal. If the cable is to pass
through tubing or a bulkhead, protect the unfinished end. Do not use
the unfinished wires or fabric braid to pull the cable. Attach a fish cord
only to the cable jacket.
♦Route the cable to the operator’s location, securing it at appropriate
points along the way. Make a drip loop and apply sealant at the entry
point of an exterior bulkhead.
1.4 RADAR JUNCTION BOX CONNECTIONS

Radar. If you use the connecting cable supplied with the Radar, the Port2 is the
default setting. In this case follow the procedure:
[MENU] + "SETUP" + [ENTER] + "Input/Output" + [ENTER] + "PORT 2 IN-
PUT" + [ENTER] + "RADAR" + [ENTER]
1.5.2 Warming Up
It has to be noted that at start-up the Radar needs a variable time from 90 to 120
seconds to heat up the magnetron (microwave emitting tube). During this time it
is not possible to turn on the transmission.
Radar pages are visible but with a small overlapping message window showing
the time remaining to Warm Up completion:
"Radar Warming Up! xx seconds remaining!"
At completion of the Warm Up sequence the following message will be displayed:
"Radar Warming Up! Warm Up Completed!"
This window shall remain open for 2 seconds, then it will close automatically.
At this point the Radar is ready for operation. Transmission is turned Off and
"STAND BY" message is displayed at the center of the Radar page.
1.5.3 Transmission On

1.5.4.1 Heading Line
Adjusting the heading ensures that target is shown at the correct heading relative
to your ship's bow. You need to select a visible target of known heading that is
shown on the Radar screen, and then adjust the Radar set up as necessary until
the correct heading is obtained. To perform the heading line alignment you can
choose one of the two following procedures: "With Your Ship Moored" and "With
Your Ship Under Way".

14 User Manual
With your ship moored
You will need a hand held heading compass, then:
♦Visually identify a Target, such as a buoy that can be seen towards the
edge of the Radar screen.
♦Determine the accurate heading of the Target relative to your ship's
bow using the hand held compass. So subtract your ship heading from
the Target visual heading.
For example:
(a) Target heading = 70° M
(b) Ship head heading = 20° M
Relative heading = (a) - (b) = 70° - 20° = 50° M
♦Now select the EBL/VRM function following the procedure:
[MENU] + "RADAR FEATURES" + [ENTER] + "EBL/VRM" + [ENTER]
♦Adjust the EBL (EBL heading) to your chosen Target. If there is a differ-
ence between you calculate the Relative heading and that shown for
the EBL, there is an alignment error and you will need to carry out
heading line alignment adjustment (see the "Adjusting the Heading
Line" below).
With your ship under way
♦Align your ship's bow with the selected Target.
♦Note the position of Target relative to the Heading Marker (HM) on the
Radar screen. If the Target is not under the HM, there is an alignment
error and you will need to carry out heading line alignment adjustment.
(see the "Adjusting the Heading Line" below).
Adjusting the Heading Line
♦With a Radar screen open, follow the procedure:
[MENU] + "TUNING" + [ENTER] + "HEADING LINE" + [ENTER]
♦Then:
If the ship is moored:apply the heading correction as
Heading correction = (EBL heading - Relative heading)
If the ship is under way: now select the EBL/VRM function following
the procedure:
[MENU] + "RADAR FEATURES" + [ENTER] + "EBL/VRM" + [ENTER]
adjust the EBL (EBL heading) as to point to the Target. Apply the
heading correction as
Heading correction = (EBL heading - Relative heading)
♦Press [ENTER]. The screen updates as the heading line is adjusted.
♦Press [CLEAR] to exit from menu.
1.5.4.2 Antenna Parking Position
When the Radar is turned Off, the antenna comes to a stop. If you want to have
the antenna to stop in a specific position, the Antenna Parking Position function
can be used to choose the desired antenna position. This function only controls
the antenna position at which the power to the motor is cut off. The distance
through which it comes to a stop from this point depends on temperature and
wind conditions. The setting of antenna does not affect the operation of the Radar
at all.
To set the antenna position follow the procedure:
[MENU] + "TUNING" + [ENTER] + "ANTENNA PARKING POSITION" +
[ENTER]
Use the cursor keys to adjust the position (between 0 and 90).
The displayed number represents the change from the default setting. The final

15

setting that parks the antenna straight ahead will likely be a few degrees left or
right from the default setting.
1.5.4.3 Sector Transmission Off
This is used to block transmission and target reflection in some special application
for fixed installation like sea watching. Within this sector, targets can not be detected.
Selecting the Sector Transmission Off from the menu:
[MENU] + "TUNING" + [ENTER] + "SELECT TRANSMISSION OFF" + [ENTER]

Fig. 1.5.4.4- Transmission Trigger Delay tuning (I)
Finally tuning the transmission Trigger Delay allows for making accurate distance
measurements. In practice, you need to align the start of the sweep with the
leading edge of the transmission pulse. Use the following procedure:
♦Set up the Radar controls as follows before doing the following set ups. Set
the GAIN to the best picture and adjust the STC (see Par. 2.2.3) until the TX
pulse can be seen as a round point in the center of the screen.
♦Adjust the transmission trigger delay to a point that the center looks as
shown in the diagram (b) below and a target such as a bridge or a breakwa-
ter displays as a straight line on the screen.

16 User Manual
Fig. 1.5.4.4a - Transmission Trigger Delay tuning (II)
Once the calibration has been performed, the calibration data is retained. How-
ever if a Clear RAM operation is performed it may be necessary to repeat the
calibration.
IMPORTANT: This tuning is already done by the factory and thus it is in general
not necessary to do it unless some components of the Radar have been changed.
1.5.4.5 Automatic and Manual Tune
The Tune control is used to tune the receiver in the Radar antenna for maximum
target returns on the display. If no land or ship targets are available, you may
tune for maximum sea clutter. The tuning indicator shows the strength of tuning
peak conditions and is tuned for maximum deflection.
The Radar receiver can be tuned in Automatic or Manual mode. To adjust manu-
ally, follow the procedure below:
[MENU] + "TUNING" + [ENTER] + "MANUAL TUNE" + [ENTER]
otherwise to select automatic tuning:
[MENU] + "TUNING" + [ENTER] + "AUTOMATIC TUNE" + [ENTER]
In Automatic Tune mode, the Radar tunes itself automatically on all range scales.
It is recommended that you leave the Tune function in Automatic mode, to ensure
that the Radar receiver is always tuned to receive the maximum signal.
If you choose Manual Tuning, you will need to adjust it again 10 minutes after you
have turned on the Radar, since the required setting will change after the magne-
tron has warmed up. You should adjust the control to obtain the maximum signal
strength.
1.5.4.6 Save Tuning to User C-CARD
This is useful to avoid the user having to retune the Radar after a Clear RAM
operation or a software update. The following data will be saved:
♦Heading Line angle
♦Antenna Parking Position
♦Sector Transmission Off Start Angle
♦Sector Transmission Off End Angle
♦Transmission Trigger Delay

2.1.1 Cross Cursor
The Cross Cursor is a symbol that shows the cursor position on the screen. It is
displayed when the Cursor Key is pressed and it is moved around the screen using
the Cursor Key. It is automatically hidden when the Cross Cursor is not used for
more than 5 seconds.
It is context-sensitive. The following table reports the list of objects and the labels
that appear under the cursor:
♦Center of Radar CTR
♦EBL/VRM E/V
♦Parallel Cursor ///
♦Guard Zone GZ
♦Ship Heading Marker HM

2.1.2 Chart Overlay
AVAILABLE ONLY IN THE RADAR FULL PAGE
This function merges Radar and chart data into a single picture by drawing Radar
targets over the cartography.
When in Chart Overlay mode, the chart inherits the Radar page setting, e.g.
Orientation, True Motion mode.
To enable (On) or disable (Off) the Chart Overlay follow the procedure:
[MENU] + "CHART OVERLAY" + [ENTER]
NOTE Requires a heading and a position sensor connected to the chart plotter
through an NMEA 0183 interface. The heading sensor can be either a
gyrocompass or a fluxgate compass. The gyrocompass provides the best
performance in all conditions.
2.1.3 Range
Selects the Radar range among 1/8, 1/4, 1/2, 3/4, 1, 1 + 1/2, 2, 3, 4, 6, 8, 12,
16, 24, 36 and 48 Nm (the maximum range depends on the antenna used).

20 User Manual
It is an alternative to the Range selection in Radar page done using [ZOOM IN]/
[ZOOM OUT].
NOTE Changing scale takes about 5 seconds.
To select the Radar Range value follow the procedure:
[MENU] + "RANGE" + [ENTER]
2.1.4 Orientation
The Radar orientation option allows for the choice of the display modes, Head Up
(HU), North Up (NU) or Track Up (TU), that refers to the top of the screen as it is
relates to the direction of the boat.
The Radar direction modes are described in the following table:
Head Up : The Radar picture is displayed with the vessel’s current heading upwards. As the heading
changes the picture will rotate. It doesn’t require heading information. It is the default value.
North Up : The Radar picture is stabilized and displayed with north upwards. As heading changes, the ship’s
Heading Marker moves. Requires a heading sensor connected to the chart plotter.
Track Up : The Radar picture is stabilized and displayed with the currently selected Course Leg upwards. As
heading changes, the ship’s heading marker moves. If you select a new course leg, the picture
rotates to display the new course leg upwards. Requires a heading sensor connected to the chart
plotter.
NOTE Head Up cannot be selected in True Motion mode.
To change the orientation mode follow the procedure:
[MENU] + "ORIENTATION" + [ENTER]
2.1.5 Motion Mode
Allows choosing between two different presentation of targets and ship position
over the Radar screen Relative Motion (RM) and True Motion (TM). See the follow-
ing table:
True Motion : In True Motion, fixed Radar targets maintain a constant position on the screen, whilst your own
ship moves across the Radar image at the appropriate speed and heading. A map-like image is
thus displayed, with all moving vessels traveling in true perspective to each other and to fixed
landmasses. As your ship’s position approaches the edge of the screen, the Radar center offset
is automatically reset to reveal the area ahead of your ship.
Relative Motion : In Relative Motion your own ship’s position remains fixed on the Radar screen and all Radar
targets move relative to your own ship. It is the default for the Radar display.
NOTE True Motion is only available in North Up and Track Up modes (not in Head Up
mode). Also True Motion requires a heading sensor and GPS position
information.
To change the Motion mode follow the procedure:
[MENU] + "MOTION MODE" + [ENTER]
2.1.6 Echo Trails Settings
Selects an appropriate trail plotting interval to help determine the speed and
course of a target vessel and help prevent collision with it. Selects Radar Trails
among Continuous, 15 seconds, 30 seconds, 1 Minute, 3 Minutes, 6 Minutes (or
disables - Off).
To choose the Echo Trails follow the procedure:
[MENU] + "ECHO TRAILS" + [ENTER]
2.1.7 Target Expansion
Allows the expansion of target size without affecting the range.
To enable (On) or disable (Off) the Target Expansion follow the procedure:
[MENU] + "TARGET EXPANSION" + [ENTER]

2.2 SENSITIVITY
To select the Sensitivity menu follow the procedure:
[MENU] + "SENSITIVITY" + [ENTER]
NOTE The Sensitivity menu can be also opened by pressing:
[ENTER]
directly from the Radar page when the Cross Cursor is not placed over any
features.
2.2.1 Interference Rejection
Reduces the interference caused by Radar signals from other Radar units. It is
possible to turn Interference Rejection to Off, Level 1 (weak), Level 2 (middle),
Level 3 (strong). The higher you set the Interference Rejection value the less
interference you will receive.
To select the Interference Rejection value follow the procedure:
[MENU] + "SENSITIVITY" + [ENTER] + "INTERF REJECTION" + [ENTER]
2.2.2 Gain Adjustment
Controls the Radar Gain. To see more details on the screen, increase the receiver
sensitivity by selecting a higher gain percentage. If there is too much detail or if
the screen is cluttered, lowering the sensitivity may increase the clarity of the
display.
To select the Gain value follow the procedure:
[MENU] + "SENSITIVITY" + [ENTER] + "GAIN" + [ENTER]
2.2.3 STC (Sensitivity Time Constant) Adjustment
Reduces the effects of the sea clutter that can adversely affect displayed targets.
To select the STC value follow the procedure:
[MENU] + "SENSITIVITY" + [ENTER] + "STC" + [ENTER]
NOTE At low scales (as 1/4 of mile) some attempts are necessary to adjust STC value.
2.2.4 FTC (Fast Time Constant) Adjustment
Reduces the effects of rain, snow, fog and cloud that can adversely affect dis-
played targets.
To select the FTC value follow the procedure:
[MENU] + "SENSITIVITY" + [ENTER] + "FTC" + [ENTER]
NOTE At low scales (as 1/4 of mile) some attempts are necessary to adjust FTC value.
2.2.5 MBS (Main Bang Suppression) Adjustment
AVAILABLE ONLY FOR RE-9/10
The MBS adjustment is fundamental for getting clear near center spot image. In
general, you must adjust MBS and STC and Gain to obtain desired Radar image.
To select the MBS value follow the procedure:
[MENU] + "SENSITIVITY" + [ENTER] + "MBS" + [ENTER]
