CAUTION

The MR-1000RII/TII are supplemental aids to navigation and are not intended to be a substi-

tute for accurate and current nautical charts.

DANGER! HIGH VOLTAGE

RADIATION HAZARD

Radiation emitted from the scanner unit can be harmful, particularly to the eyes. To avoid harm-

ful radiation, ensure the radar power is in the OFF position before beginning work on the scan-

ner unit.

• NEVER OPEN THE UNIT

This product contains high voltage that could be FATAL. This product has no user-service-

able parts inside. All repairs and adjustments MUST be made by a qualiﬁed electronics tech-

nician 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

■ Advanced measurements

Using both Electronic Bearing Lines (EBL) and both

Variable Range Markers (VRM), the following ad-

vanced measurements can be made:

D Measuring the distance and direction between 2 targets

q Push [Ù Ú Ω ≈] to move the cursor on the desired

target.

w Push [EBL1 (VRM1)]/[ ] to display the

EBL1 and VRM1.

• Push [Ω ≈] to rotate the electronic bearing line.

• Push [Ù Ú] to increase or decrease the variable range

marker ring size.

e Push [EBL2 (VRM2)]/[ ] to display the

EBL2 and VRM2.

• The intersection of the EBL1 and VRM1 becomes the

center of the EBL2 and VRM2.

r Push [Ù Ú Ω ≈] to move the cursor on the other

target.

• Push [Ω ≈] to rotate the electronic bearing line.

• Push [Ù Ú] to increase or decrease the variable range

marker ring size.

t The VRM2 readout shows the distance between the

two targets. The EBL2 readout shows the direction

from one target to the other.

D Measuring the relative speed and course of a target

q Push [TRAILS]/[ ] (p. 12) ON; then wait until

the trail time count up reaches to the TRAIL TIME.

w Set VRM1 and EBL1 to a previously plotted target

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, multi-

plying 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 nauti-

cal miles (NM) or kilometers (KM), respectively.

t The EBL2 readout shows the course direction of the

target.

• Measuring the distance and course from a waypoint

q Display a waypoint. (see p. 13)

w Set VRM1 and EBL1 to the displayed waypoint tar-

gets as described above.

e Set VRM2 and EBL2 to a target (e.g. the next way-

ALARM FUNCTION

MR-1000R2_T2.qxd 04.2.24 10:22 Page 17

■ 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 ap-

proach 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.

• The vector will be displayed on the target.

• Display accuracy may increase by the self-ship and course change of target or acceleration, slowdown, etc.

■ 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.

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.

■ Side-lobe echoes

Radiation can escape on each side of the beam inside

the lobes. If a target reﬂects this radiation, it will be dis-

played on the screen as an echo.

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.

False

echoes

True

Main beam

Side lobes

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 ef-

fects of these phenomena. In some cases, echoes can be reduced.

BASIC RADAR THEORY

■ Multiple echoes

Multiple echoes may appear when a short-range and

strong echo is received from a ship, bridge, or break-

water.

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.

True echo

False echoes

Own ship

■ 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 mea-

sured.

The ability to see targets very close to the ship is de-

creased if the scanner is mounted too high off the

water, because the bottom of the vertical beam of the

scanner cuts off nearby targets.

This target can not be recognized with radar.

The target in this area can not be recognized.

Vertical beam width

MR-1000R2_T2.qxd 04.2.24 10:22 Page 22

BASIC RADAR THEORY

■ Blind and Shadow sectors

Blind or Shadow sectors may exist because of ob-

structions such as masts, derricks or stacks. An ob-

struction 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.

When tall and massive targets such as a large island

are located at close range also shadowed without pro-

ducing 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.

■ 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 dis-

tances or which are in the same direction.

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.

■ Connecting the units

NMEA1 connection NMEA2 connection

■ Power source requirement

D DC power source

The radar is designed for connection to any power

source if the voltage is 10.2–42 V DC, so that a 12, 24,

or 32 V DC battery can be used without a DC-DC con-

verter, or any internal modiﬁcations.

• DC power cable connection

Connect the supplied DC power cable as shown in the

diagram.

■ Ground connection

To prevent electrical shocks and other problems, ground the display unit through the [GND] terminal on the unit’s

rear panel. For best results, connect a heavy gauge wire or strap to the nearest grounding point on the boat. The

distance between the [GND] terminal and the ground point should be as short as possible.

CAUTION: Incorrect cable connection may dam-

age the radar.

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.

■ Periodic maintenance

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.

■ Scanner unit maintenance

D Cleaning

q Wipe the surface of the scanner with a clean soft

cloth.

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

hol.

w Check that there is no drift or caked salt.

• A heavy deposit of dirt or caked salt on the painted sur-

face 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

D Cleaning

Dirt on the CRT will, in time, leave a ﬁlm of contami-

nates 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 (65

⁄8 ft) apart.

• OPC-1078 SYSTEM CABLE

Allows you to install the display unit and scanner up to 30 m (98

⁄

16 ft) apart.
