DANGER! HIGH VOLTAGE

• NEVER OPEN THE UNIT

This product contains high voltage that could be FATAL. This product has no user-service­able parts inside. All repairs and adjustments MUST be made by a qualified electronics tech­nician at your Marine Navigation Dealer.

• HIGH VOLTAGE

High voltages of up to 3,500 volts are used in this equipment. Although prudent measures for
safety have been adopted, sufficient care must be taken in the operation, maintenance and
adjustment of the equipment.

Electric shock of 1,000 volts or more may cause electrocution and death; even an electric
shock of only 100 volts may be fatal.

• PREVENTION OF ELECTRIC SHOCK

(FOR QUALIFIED ELECTRONIC TECHNICIANS ONLY)

To prevent such accidents, turn OFF the power source and do not reach inside the unit until
you have:

q discharged the capacitors by disconnecting the power cable from the power source for

5 min.;

w checked that no electric charges remain inside the device.

at close range. Reduce the receiver gain for close ob­jects within a radius of 8 miles to eliminate sea clutter.

• Rotate the control fully clockwise to activate the automatic
control function. SEA indicator ( )appears in the upper left
of the screen.

WARNING: The [SEA]/[ ] control re-

duces the receiver sensitivity of objects within 8
miles. Therefore, caution and careful adjustment are
necessary when using the [SEA]/[ ] control.
Small objects may not be displayed on the screen
when strong echoes from the rain or the island within
1 NM while automatic SEA function is activating.

as described above.

e Set VRM2 and EBL2 to the current plotted position

of the same target as described as above.

r The VRM2 readout is a measure of target move-

ment which can be converted into relative target
speed.

• For example, when a 6 min. trail time is selected, multi­plying the distance by ten gives the relative average
speed of the target.

• If your ship is stationary during the plotting time, the
converted speed and direction become absolute.

• The converted speed unit is knots or kilometers/hour
when the selected unit in the FUNCTION menu is nauti­cal miles (NM) or kilometers (KM), respectively.

t The EBL2 readout shows the course direction of the

target.

r The VRM2 readout shows the distance to the target

from the waypoint.

•The distance unit can be selected as nautical miles (NM)
or kilometers (KM) in the FUNCTION menu.

ATA (Automatic Tracking Aid)

■ ATA (Automatic Tracking Aid)

By tracking automatically the target chosen by the cursor key, the closest point of approach (CPA) and the time to
closest point of approach (TCPA) limit of a own ship and a target are calculated.
ATA is the function to tell about to alarm sound, when both CPA and TCPA becomes below a setting value (the ap­proach watch area).
The range of the target which can be registered is taken as a target with a highest luminosity level of 0.2–16 miles.

• Max. 10 targets can be plotted on the screen.

• Plot positions shall be identified by an approved symbol mark (p. 20) and associated plot number.

• The vector origin will move across the screen at a rate and direction defined by the calculated true or relative

course and speed.

BASIC RADAR THEORY

Radar uses a form of electromagnetic radiation, which like light, can be reflected. Because of this property, some
objects may cause false echoes on the screen where in fact no targets actually exist.
These echoes may appear if a large vessel, bridge, or tank is in proximity. Operators should be familiar with the ef­fects of these phenomena. In some cases, echoes can be reduced.

8

■ Side-lobe echoes

Radiation can escape on each side of the beam inside
the lobes. If a target reflects this radiation, it will be dis­played on the screen as an echo.

■ Indirect echoes

Indirect echoes may be returned from either a passing
ship, or returned from a reflecting surface, such as a
mast on your own ship.

Side-lobe echoes usually occur at short ranges and as
a result of large (strongly reflective) targets. They can
be reduced with proper adjustment of the
[SEA]/[ ] control.
See p. 10 for the [SEA]/[ ] control.

An indirect echo from a reflecting surface will appear
on a different bearing from the direct (true) echo, but
the distance will be approximately the same for both.

Pulse length

BASIC RADAR THEORY

■ Multiple echoes

Multiple echoes may appear when a short-range and
strong echo is received from a ship, bridge, or break­water.

■ Minimum range

Detection at short range is very important. Minimum
range is determined primarily by transmitter pulse
length, vertical beam width and height of the scanner
unit. The shorter the transmission time, the quicker the
return echoes can be received and their distance mea­sured.

Multiple echoes will appear beyond the target’s true
echo point on the same bearing of a large target. They
can be reduced with proper adjustment of the
[SEA]/[ ] control.
See p. 10 for the [SEA]/[ ] control.

The ability to see targets very close to the ship is de­creased if the scanner is mounted too high off the
water, because the bottom of the vertical beam of the
scanner cuts off nearby targets.

Blind or Shadow sectors may exist because of ob­structions such as masts, derricks or stacks. An ob­struction may throw either a complete or partial
shadow as shown in the diagram below. If a target is in
a shadow sector, target echoes may not appear on the
screen.

■ Target resolution

Target resolution is determined by the horizontal beam
width and transmit pulse width. Sometimes it is difficult
to detect two targets which are separated by short dis­tances or which are in the same direction.

When tall and massive targets such as a large island
are located at close range also shadowed without pro­ducing any echoes. This phenomenon is called blind
sector. It is very important to know the bearings and
widths of all shadow sectors caused by your own
ship’s obstructions.

D Distance resolution

When two targets are separated by more than the
pulse width, they appear as two echoes.

When two targets are not separated by more than
the pulse width, they appear as 1 echo.

D Direction resolution

When two targets are separated by more than the
horizontal beam width, they appear as two echoes.

When two targets are not separated by more than
the horizontal beam width, they appear as one echo.

Continued, reliable operation of the radar depends on how you care for your equipment. The simple maintenance
tips that follow can help you save time and money, and avoid premature equipment failures.

MAINTENANCE

■ Periodic maintenance

WARNING: BE SURE the power is OFF before

performing any maintenance.

■ Scanner unit maintenance

WARNING: BE SURE the power is OFF before

working on the radar.

q Keep the equipment as clean as possible.

• Use a soft cloth to remove dirt, dust and water.

w Check all hardware for loose screws, bolts, etc.
e Check cables and terminal connections.

D Cleaning

q Wipe the surface of the scanner with a clean soft

cloth.

• DO NOT use strong solvents such as benzene or alco­hol.

w Check that there is no drift or caked salt.

• A heavy deposit of dirt or caked salt on the painted sur­face of the upper scanner unit will cause a considerable
drop in radar performance.

e Check for cracks or deterioration of the rubber

packing and replace it if necessary.

D Painting (MR-1000TII only)

To prevent the corrosion, paint the surface of the
scanner body (except the antenna unit) twice a year
or more.

D Mounting

Check the mounting bolts of the scanner unit and
tighten if necessary.

■ Display unit maintenance

WARNING: BE SURE the power is OFF before

working on the radar.

D Cleaning

Dirt on the CRT will, in time, leave a film of contami­nates which tend to dim the picture.

q Wipe the surface of the display unit with a clean soft

cloth.

• DO NOT use strong solvents such as benzene or alco-
hol.

w If the picture is still dim, clean the CRT screen.

■ Options

• OPC-1077 SYSTEM CABLE

Allows you to install the display unit and scanner up to 20 m (655⁄8 ft) apart.

• OPC-1078 SYSTEM CABLE

Allows you to install the display unit and scanner up to 30 m (987⁄

• “HDT”, “HDM”, “RMC”, “GGA”, “GLL”, “VTG”, “WPL”, “GNS” and “BWC” are SENTENCES of the NMEA0183.

•If BRG INPUT is set to “GPS”, “RMC” of NMEA2 connector or COG (Course Over the Ground) of “VTG” a bow it
receives as a direction, even if there is no direction information (compass etc.) in NMEA1 connector, the screen
display of the North rise etc. is possible.

However, direction accuracy falls when the speed of a ship is set to 2 or less kts, or when exceeding 3 kts a bow
it does not receive as direction data. Moreo, the influence of measurement position accuracy or a current an actual
bow it may differ from a direction.
