![iiFOREWORDThank you for purchasing Icom’s MR-1000RII/TII MA-RINE RADAR. The radar is designed especially for fishing boats. Ithas powerful transmission power, 10 inch CRT displayand many other advanced features. If you have any questions regarding the operation ofthe radar, contact your nearest authorized Icom Inc.dealer.IMPORTANTREAD ALL INSTRUCTIONS carefully and com-pletely before attempting to operate the marine radar.SAVE THIS INSTRUCTION MANUAL. Thismanual contains important safety and operating in-structions for the MR-1000RII/TII.EXPLICIT DEFINITIONSThe following explicit definitions apply to this instruc-tion manual. PRECAUTIONRNEVER let metal, wire or other objects touch anyinternal part of the radar.RNEVER place the radar within the reach of chil-dren.RNEVER expose the display unit to rain, salt wateror any other liquids.NEVER connect the radar to AC or more than 42 VDC. 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 en-vironments.AVOID placing the display unit near heating equipmentor in direct sunlight or where hot or cold air blows di-rectly onto it.AVOID using the scanner unit in areas where the tem-perature is below –25˚C (–13˚F) or above +70˚C(+158˚F). AVOID using the display unit in areas wherethe temperature is below –15˚C (+5˚F) or above +55˚C(+131˚F).AVOID using strong solvents such as benzene or al-cohol for cleaning the radar, as they may damage thesurfaces. BE CAREFUL!SART signal may not be detected and maynot be displayed on the screen dependingon the SEA, RAIN or IR settings.Follow the settings as below to detect theSART signal on the screen.qSelect the screen range between 6 NMto 12 NM with [+/–]. (p. 2)wSet the [GAIN] as high as possible. (p. 3)eSet the [SEA] to minimum. (p. 3)rSet the [RAIN] to minimum. (p. 3)tTurn the [IR] OFF.yTurn the [STRETCH] OFF.WORDR WARNINGCAUTIONNOTEDEFINITIONPersonal injury, fire hazard or electric shock may occur.Equipment damage may occur.If disregarded, inconvenience only.

![104BASIC OPERATIONThe following are typical basic operation examples, which may hinder radar reception (sea clutter, precipitation in-terference and echoes from other radar).■RAIN functionThis function eliminates reflection echoes from rain,snow, fog etc. •Rotate the control fully counterclockwise to deactivate thecontrol function. The RAIN indicator ( ) disappears.•NOTE: DO NOT reduce the reflection echoes too much,otherwise you may miss weaker targets. ■SEA functionThis function serves to eliminate echoes from wavesat close range. Reduce the receiver gain for close ob-jects within a radius of 8 miles to eliminate sea clutter.•Rotate the control fully clockwise to activate the automaticcontrol function. SEA indicator ( )appears in the upper leftof the screen.■OFF CENTER functionThe scanning area can be shifted in a desired direc-tion and can be enlarged partially. This is useful whenthe Head-up* is selected and you want to enlarge thebow direction display, or, the center of the screen shiftsin the direction of the intersection. •This function is available for 24NM or shorter range selec-tion.*This function is not available in the TM screen.qPush [Ù Ú Ω ≈] to move the cursor where youwant to shift the center of the screen.• Max. offsetting is up to 75% of the screen.wPush [ALM] and [MODE] simultaneously to shiftthe screen.ePush [ALM] and [MODE] simultaneously again toreturn to the normal screen.With OFF CENTER ONNormal screenAdjust SEA controlEchos from sea wavesAdjust RAIN controlSmall echosWARNING: The [SEA] control reduces the re-ceiver sensitivity of objects within 8 miles.

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 asa result of large (strongly reflective) targets. They canbe reduced with proper adjustment of the [SEA] con-trol. See p. 10 for the [SEA] control.FalseechoesTrueechoMain beamSide lobesRadar uses a form of electromagnetic radiation, which like light, can be reflected. Because of this property, someobjects 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. 8BASIC RADAR THEORY21MR-1000R2_T2_FCC.qxd 05.5.17 9:18 Page 21](https://usermanual.wiki/ICOM-orporated/271400.Manual/User-Guide-581274-Page-25.png)
![8BASIC RADAR THEORY22■Multiple echoesMultiple echoes may appear when a short-range andstrong echo is received from a ship, bridge, or break-water. Multiple echoes will appear beyond the target’s trueecho point on the same bearing of a large target. Theycan be reduced with proper adjustment of the [SEA]control. See p. 10 for the [SEA] control.True echoFalse echoesOwn ship Another ship■Minimum rangeDetection at short range is very important. Minimumrange is determined primarily by transmitter pulselength, vertical beam width and height of the scannerunit. The shorter the transmission time, the quicker thereturn 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 thewater, because the bottom of the vertical beam of thescanner cuts off nearby targets.This target can not be recognized with radar.The target in this area can not be recognized.Pulse lengthPulse starting pointVertical beam widthMR-1000R2_T2_FCC.qxd 05.5.17 9:18 Page 22](https://usermanual.wiki/ICOM-orporated/271400.Manual/User-Guide-581274-Page-26.png)
