CAUTION
1
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
• 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
5 min.;
w checked that no electric charges remain inside the device.
Also, it is safest to wear dry insulated rubber gloves. NEVER use both hands simultaneously;
keep one hand in your pocket.
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.

The unit has an alarm function to protect your ship from collisions. If other ships or islands, etc. come into the pre-
programmed alarm zone, the function alerts you with an alarm. You can set the desired range and bearing for an
alarm zone. While the alarm function is activated, the power save function turns the CRT OFF until an alarm is

I 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.

BASIC RADAR THEORY
8
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.
I 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.

True

False
echoes
I 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.

BASIC RADAR THEORY
I 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.

I 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.
Vertical beam width

BASIC RADAR THEORY
I 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.

I 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.
DDistance resolution
DDirection resolution
When two targets are separated by more than the
pulse width, they appear as two echoes.
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 pulse width, they appear as 1 echo.
When two targets are not separated by more than
the horizontal beam width, they appear as one echo.

MAINTENANCE
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.
I Periodic maintenance
qKeep the equipment as clean as possible.
•Use a soft cloth to remove dirt, dust and water.
wCheck all hardware for loose screws, bolts, etc.
WARNING: BE SURE the power is OFF before
performing any maintenance.
eCheck cables and terminal connections.
I Scanner unit maintenance
DCleaning
WARNING: BE SURE the power is OFF before
qWipe the surface of the scanner with a clean soft

cloth.
•DO NOT use strong solvents such as benzene or alco-
hol.
wCheck 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.
eCheck for cracks or deterioration of the rubber
packing and replace it if necessary.
DPainting (MR-1000TII only)
To prevent the corrosion, paint the surface of the
scanner body (except the antenna unit) twice a year
or more.
DMounting
Check the mounting bolts of the scanner unit and
tighten if necessary.
