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 qualied 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, sufcient 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.

(KT) or kilometers/hour (KM/h) are automatically se-  
lected in the normal screen (p. 4) by selecting nautical  
miles (NM) or kilometers (KM) respectively.  
To magnify the blips for easier viewing of small targets,  
the long pulse and echo stretch (p. 11) functions are  
available. When the long pulse is used in the 4 to  
2 NM range, this function magnies target echoes to  
the backward direction of the target.

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 0.216 miles.  
Max. 10 targets can be plotted on the screen.  
Plot positions shall be identied by an approved symbol mark (p. 20) and associated plot number.  
The vector origin will move across the screen at a rate and direction dened 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 reected. 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 reects 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 reective) targets. They can  
be reduced with proper adjustment of the

] control.

I Indirect echoes  
Indirect echoes may be returned from either a passing  
ship, or returned from a reecting surface, such as a  
mast on your own ship.  
An indirect echo from a reecting 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 targets 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.  
False echoes  
True echo  
Own ship

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.

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  
ships obstructions.

I Target resolution  
Target resolution is determined by the horizontal beam  
width and transmit pulse width. Sometimes it is difcult  
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.

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
