FOREWORD
Thank you for purchasing Icom’s MR-1000RII/TII/TIII
MARINE 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 the MR-1000RII/TII/TIII.
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 the SEA, RAIN or IR settings.
Follow the settings as below to detect the SART signal on the screen.
qSelect 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/TII/TIII are 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.
(See p. 24 for details.)

The heading marker is a line that shows your ship’s bow direction. (This marker will appear in the center of the screen when the Head-up screen H UP is selected.) The heading marker can be hidden when the desired target is located under the heading marker.
•Push and hold [BRILL]/[] and [MENU]/[] simultaneously to hide the heading marker.
DFixed range rings
The fixed range rings can be used for rough distance measurement. (p. 14)

BASIC OPERATION 4
q Turn the power ON.
w Push [TX]/[] after the countdown disappears from the screen.

ePush [+]/[] or [–]/[ ] several times to select the display range.
•The screen range readout shows the maximum range of the screen.
rTurn [GAIN]/[] to set 1 o’clock position.
•Clockwise rotation increases the gain.
•Increased gain may increase screen noise.
tTurn [SEA]/[] to set the sensitivity time control for minimum.
yTurn [RAIN]/[] to set the rain clutter control for minimum.
uPush [MODE]/[ ] to select one of Head-up;H UP, Course-up;C UP, North-up;N UP or True Motion;TM screens.
C UP, N UP or TM can be selected only when bearing, position or speed data are connected.
(See p. 39 for details)
NOTE: Manual adjustment can be used. (See below.)
DManual tuning
The receiver tuning can be manually adjusted. Push [MENU]/[] to open the VIDEO menu, then
select MANUAL. Push [Ú] to activate the manual tuning slider, then push [Ω ≈] to set the tuning level indicator to the maximum level. (p. 6)
• “M.TUNE” appears on the top of the display.
DBrilliance adjustment
The intensity of the screen can be adjusted. When you require continuous operation, but not constant viewing, a lower setting can increase the life of the CRT display.
NOTE: High intensity will shorten the life of the CRT display.
• Key illumination
The backlighting of the keys can be adjusted for convenient operation. (p. 7)
Push [MENU]/[] four times to call up the INT. SETTING menu. Push [Ω ≈] to select the illumination level.

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
This function serves to eliminate echoes from waves at close range. Reduce the receiver gain for close objects within a radius of 8 miles to eliminate sea clutter.
• Rotate the control fully clockwise to activate the automatic control function. SEA indicator ()appears in the upper left
|
|
|
of the screen. |
|
|
|
|
|
|
|
|
|
