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

rPush [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.
tThe VRM2 readout shows the distance between the
two targets. The EBL2 readout shows the direction
from one target to the other.
DMeasuring the relative speed and course of a target
qPush [TRAILS]/[ ] (p. 12) ON; then wait until
the trail time count up reaches to the TRAIL TIME.
wSet VRM1 and EBL1 to a previously plotted target
as described above.
eSet VRM2 and EBL2 to the current plotted position
of the same target as described as above.
rThe 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.
tThe EBL2 readout shows the course direction of the
target.
•Measuring the distance and course from a waypoint
qDisplay a waypoint. (see p. 13)
wSet VRM1 and EBL1 to the displayed waypoint tar-
gets as described above.
eSet VRM2 and EBL2 to a target (e.g. the next way-
point) as described above.
rThe 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.
tThe EBL2 readout shows the direction to the target
from the waypoint.
