FOREWORD

Thank you for purchasing Icom’s MR-1000RII/TII MA-

RINE RADAR.

The radar is designed especially for fishing boats. It has powerful transmission power, 10 inch CRT display and many other advanced features.

If you have any questions regarding the operation of the radar, contact your nearest authorized Icom Inc. dealer.

IMPORTANT

READ ALL INSTRUCTIONS carefully and completely before attempting to operate the marine radar.

SAVE THIS INSTRUCTION MANUAL. This manual contains important safety and operating instructions for theMR-1000RII/TII.

EXPLICIT DEFINITIONS

The following explicit definitions apply to this instruction manual.

WORD

DEFINITION

RWARNING

Personal injury, fire hazard or electric

 

shock may occur.

CAUTION

Equipment damage may occur.

 

 

NOTE

If disregarded, inconvenience only.

No risk of personal injury, fire or

 

electric shock.

 

 

PRECAUTION

RNEVER let metal, wire or other objects touch any internal part of the radar.

RNEVER place the radar within the reach of children.

RNEVER expose the display unit to rain, salt water or any other liquids.

NEVER connect the radar to AC or more than 42 V DC. This will damage the radar.

AVOID using the radar near any magnetic materials, such as a loudspeaker or a large power transformer, as this can cause distortion of the CRT display.

AVOID placing the display unit in excessively dusty environments.

AVOID placing the display unit near heating equipment or in direct sunlight or where hot or cold air blows directly onto it.

AVOID using the scanner unit in areas where the temperature is below–25˚C(–13˚F)or above +70˚C (+158˚F).AVOID using the display unit in areas where the temperature is below–15˚C(+5˚F) or above +55˚C (+131˚F).

AVOID using strong solvents such as benzene or alcohol for cleaning the radar, as they may damage the surfaces.

BE CAREFUL!

SART signal may not be detected and may not be displayed on the screen depending on theSEA,RAIN orIR settings.

Follow the settings as below to detect the

SART signal on the screen.

q Select the screen range between 6 NM to 12 NM with [+/–].(p. 2)

w Set the [GAIN] as high as possible. (p. 3) e Set the[SEA] to minimum. (p. 3)

r Set the [RAIN] to minimum. (p. 3) t Turn the[IR] OFF.

y Turn the [STRETCH] OFF.

CAUTION 1

The MR-1000RII/TIIare supplemental aids to navigation and are not intended to be a substitute 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 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:

qdischarged 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 harmful radiation, ensure the radar power is in the OFF position before beginning work on the scanner unit.

4 BASIC OPERATION

Checking the installation

Before turning the power ON, be sure all the connections are complete. The checklist at right may be helpful for necessary confirmation.

CAUTION: Connect the scanner unit before turning the power ON. Otherwise the magnetron inside the scanner unit might be damaged.

DChecklist

qThe 4 bolts securing the scanner unit must be firmly tightened.

wCabling must be securely attached to a mast or mounting material, and must not interfere with the rigging.

eBe sure waterproofing procedures are completed on the system cable.

rThe power connections to the battery must be of the correct polarity.

tBe sure that the plugs at the rear of the display unit have been connected correctly and securely.

4 BASIC OPERATION

The following are typical basic operation examples, which may hinder radar reception (sea clutter, precipitation interference and echoes from other radar).

RAIN function

This function eliminates reflection echoes from rain, snow, fog etc.

• Rotate the control fully counterclockwise to deactivate the control function. The RAIN indicator () disappears.

NOTE: DO NOT reduce the reflection echoes too much, otherwise you may miss weaker targets.

Small echos Adjust RAIN control

SEA function

When the EBL1 and VRM1 are displayed, the beginning of EBL2 and VRM2 appears at the intersection point of the EBL1 and VRM1.

The EBL2 and VRM2 disappears when [EBL1 (VRM1)] /[]is pushed.

yTo clear the EBL1 and VRM1, push [EBL1 (VRM1)] /[].

wPush [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.

ePush [EBL2 (VRM2)]/[] to display the EBL2 and VRM2.

The intersection of the EBL1 and VRM1 becomes the center of the EBL2 and VRM2.

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.

Measuring the distance and course from a waypointq Display a waypoint. (see p. 13)

wSet VRM1 and EBL1 to the displayed waypoint targets as described above.

eSet VRM2 and EBL2 to a target (e.g. the next waypoint) as described above.

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 movement 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.

tThe EBL2 readout shows the course direction of the target.

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.
