Operating Precautions
To avoid electrical shock, never touch the inside of the scanner or
display unit. Leave protective cover on.
High voltage present inside of these units could cause personal injury.
Refer equipment servicing to authorized JRC personnel.
Avoid routinely entering the nearby vicinity of the scanner unit.
The scanner unit rotates quickly and could cause personal injury. The
scanner should be installed in a high place such as the cabin roof,
flying bridge, radar mast, or the top base frame of your ship. If the
scanner cannot be located out of normal human reach, it should be
surrounded with a fence. Prolonged human exposure to radar signals
at close range is not recommended.
Before approaching or removing the scanner unit, turn off the STBY/
OFF and X MIT/OFF keys on the display unit. Cable connector P1 on
the display unit should be disconnected before removing the scanner
unit from its installed position.
Never sit on the scanner unit.
The radome and/or the parts in the scanner unit may be damaged.
Use your RADAR 3000 system properly by following the instructions
in this manual.
Incorrect operation can detract from optimum system performance.
This radar unit is only an aid to navigation. Its accuracy can be af
fected by many factors including equipment failure or defects, envi
ronmental conditions, and improper handling or use. It is the user’s
responsibility to exercise common prudence and navigational judge
ment. This radar unit should not be relied upon as a substitute for such
prudence and judgment.

SECTION 3
This section provides practical guidelines to assist in the planning and installa
tion of the RADAR 3000 aboard your vessel.
3.1 UNPACKING AND INSPECTION
Use care when unpacking the RADAR 3000 radar from the shipping carton to
prevent damage to the contents. It is also good practice to save the carton and
the interior packing material until the radar has been satisfactorily installed on
the vessel. The original packing material should be used in the unlikely event
that it is necessary to return the unit for service.
3.2 PLANNING THE INSTALLATION
The layout for installing the RADAR 3000 should be planned to give the best
operation and service aboard your particular vessel. In general, the scanner unit
should be mounted as high as possible above the waterline. The display unit
should be installed in a convenient viewing position near the helm. Keep in
mind the optimum viewing angle when installing the display. You may want to
apply power in advance of installing the unit as that you can determine a satis
factory viewing angle.
A 10 meter length of interunit cable is furnished for interconnecting the two
main units (scanner and display). This length of interunit cable should be suffi
cient to complete the cable run required on most small vessels. It is recom
mended that the maximum length of interunit cable not exceed 20 meters.
A general system diagram for the RADAR 3000 is shown on the following
page.

3.3 MOUNTING THE DISPLAY UNIT
When planning the installation for your display unit, the following conditions
should be considered to ensure dependable and trouble free operation.
1) The mounting location should be easily accessible to allow operation of the
front panel controls.
2) There should be adequate ventilation.
3) There should be sufficient space behind the display unit to allow cable con
nections to the rear panel connectors.
4) The display unit should be located near a DC power source.
5) The selected location should be far enough away from device that may cause
interference, such as motors and generators.
6) Generally, the display unit should be located in a protected area away from
prolonged direct exposure to rain and salt spray. It is good practice to pro
tect your valuable electronic equipment as much as possible.
The display unit can be conveniently mounted on a chart table, or bulkhead
mounted in a desired location. Using the outline of FIG 3 1 and 3 2 as a guide,
install the display unit and secure to the mounting surface.

3.4 MOUNTING THE SCANNER UNIT
Selecting an adequate location for the scanner unit requires careful consider
ation. On many small vessels, the unit can be installed on a mast platform, on
an arch, or on a bridge structure near the ship’s centerline.
The radiator beam should not be obstructed by nearby large objects. Locate the
unit where large structures such as superstructures, searchlight, horns or masts
are not in the same horizontal plane, otherwise, blind areas and false targets can
appear on the radar screen.
Using the outline drawing of FIG 3 3 or template in the front of the manual as
a guide, install the scanner unit and secure it to a solid mounting surface.
Usually the mounting surface for the scanner unit should be parallel with the
ship’s waterline. Some vessels, however, may adopt a higher bow angle when
the vessel is at its cruising speed. This substantially alters and raises the radar’s
radiation plain. In this case nearby target detection might be poor. It may be
helpful to lower the radar beam towards the parallel by shimming the radar
pedestal so as to tilt the beam angle slightly downward with respect to the wa
terline.
3.5 CONNECTING THE SCANNER UNIT CABLE
①Route the scanner unit cable from bottom of the mounting base and connect
them to connectors J1 and W1 of the CME 229 modulator printed circuit
board.
②Tighten the ground terminal and securing the clamping plate with the rub
ber grommet.

3.6 ELECTRICAL CONNECTION
3.6.1 DC POWER CABLE
The RADAR 3000 will work with any ship’s mains within the 10.2 to 42 V
range, since it contains a power regulator circuit. Connect the power cable to a
DC source. The power cable normally should be wired through the circuit breaker.
The white lead wire of the power cable should be connected to the positive
source terminal and the black lead to negative source terminal. The shielded
wire should be connected to the ship’s RF ground. Should the power connec
tions be inadvertently reversed, a protective fuse will blow. Recheck the input
power leads for correct polarity with a VOM and reconnect the leads observing
correct polarity. Replace the fuse.

INSTALLATION
3.6 ELECTRICAL CONNECTION
3.6.1 DC POWER CABLE
The RADAR 3000 will work with any ship’s mains within the 10.2 to 42 V
range, since it contains a power regulator circuit. Connect the power cable to a
DC source. The power cable normally should be wired through the circuit breaker.
The white lead wire of the power cable should be connected to the positive
source terminal and the black lead to negative source terminal. The shielded
wire should be connected to the ship’s RF ground. Should the power connec
tions be inadvertently reversed, a protective fuse will blow. Recheck the input
power leads for correct polarity with a VOM and reconnect the leads observing
correct polarity. Replace the fuse.

To connect with NAV-AID and/or compass, make sure pin as-
si nment, if used same connector.
In case of different pin assi nment, the RADAR 3000 or con-
nected NAV-AID will be dama ed.

13INSTALLATION
The RADAR 3000 will interface with any NAV AID (GPS or LORAN) and
compass that has the standard NMEA0182 or NMEA0183 output. The inputs
from NAV AID will be digital data conforming to the NMEA0183 formats to
drive various radar features such as waypoint mode. If more than one data type
is present at the radar inputs (for example; compass and NAV AID), a system
priority has been established in the radar’s software to respond to the inputs in
driving the features. The assigned priorities are set in this manner:
HEADING: 1. Compass (NMEA0183 “HSC,HDM,HDT,VHW”)
2. NAV AID (NMEA0183 “RMC,RMA,VTG”)
POSISION: 1. NAV AID (NMEA0183 “RMC,RMA,GLL,GTD”)
SPEED: 1. NAV AID (NMEA0183 “RMC,RMA,VTG”)
2. Compass (NMEA0183 “VHW”)
WAYPOINT: 1. NAV AID (NMEA0183 “RMB,BWC”)
Using the outline of FIG 3 5 as a guide, connect the RADAR 3000 to your
NAV AID and compass.
