The control panel lights and atimer displays the time remaining for warmup of the magnetron (the device whichproduces radar pulses), counting downfrom 1:30.Note: When the power is reapplied within acertain amount of time and circuitsremain charged, the warmup processis skipped—you can transmit withoutone and a half minutes st-by time.The radar antenna emits high frequency radio radiation which can be harmful, particularly to your eyes. Never look directly at the antenna from a distance of less than three feet when the radar is in operation. Always make sure no one is near the antenna before turning on the radar.WARNING!](https://usermanual.wiki/Furuno-USA/9ZWRTR065/User-Guide-107590-Page-11.png)
![2-3Note: When the heading signal is lost, theHDG readout at the top of the screenshows ***.*. This warning stays onwhen the heading signal is restoredto warn the operator that the readoutmay be unreliable. After confirmingthe heading readout (if necessary,adjust it), the warning may be erasedby pressing the [DISP MODE] key.2.4 TransmittingAfter the power is turned on and themagnetron has warmed up, ST-BY (Stand-By) appears at the screen center. Thismeans the radar is now fully operational. Instand-by the radar is available for use atanytime—but no radar waves are beingtransmitted.Press the [ST-BY TX] key to transmit.When transmitting, any echoes reflectedfrom targets appear on the display. Thisradar displays echoes in four tones of grayaccording to echo strength.When you won’t be using the radar for anextended period but want to keep it in astate of readiness, press the [ST-BY TX]key to set the radar in stand-by.2.5 Selecting the RangeThe range selected automaticallydetermines the range ring interval, thenumber of range rings, pulselength andpulse repetition rate, for optimal detectioncapability in short to long ranges.ProcedurePress the [– RANGE +] key. The range andrange ring interval appear at the top leftcorner on the display.Tips for selecting the range•When navigating in or around crowdedharbors, select a short range to watchfor possible collision situations.•If you select a lower range while onopen water, increase the rangeoccasionally to watch for vessels thatmay be heading your way.2.6 Adjusting LCDBacklighting and DisplayToneThe [BRILL] key adjusts the LCDbacklighting in eight levels, including off.The [TONE] key adjusts the tone (contrast)of the display in 32 levels, including off.Procedure1.

Press the [ECHO] key to finish.How to adjust the GAIN (sensitivity)The GAIN works in precisely the samemanner as the volume control of abroadcast receiver, amplifying the signalsreceived.You can adjust the GAIN automatically ormanually. If you select AUTO, the GAINautomatically adjusted. The range of theGAIN adjustment is from 1 to 3; 3 is thehighest. For manual adjustment, adjust thesensitivity on the highest range—thebackground noise is clearer on that range.The range of GAIN adjustment is from 01to 41. The proper setting is such that thebackground noise is just visible on thescreen. If you set up for too little GAIN,weak echoes may be missed.On the contrary excessive GAIN yields toomuch background noise; strong targetsmay be missed because of the poorcontrast between desired echoes and thebackground noise on the display.](https://usermanual.wiki/Furuno-USA/9ZWRTR065/User-Guide-107590-Page-13.png)
![2-6Adjusting FTCTo suppress rain clutter from heavy stormsor scattered rain clutter, adjust the FTCamong 0, 1 and 2 (0 is off). The FTC circuitsplits up these unwanted echoes into aspeckled pattern, making recognition ofsolid targets easier. FTC and selected levelappear at the top right-hand corner of thedisplay when the circuit is turned on.Note: In addition to reducing clutter, theFTC can be used in fine weather toclarify the picture when navigating inconfined waters. However, with thecircuit activated the receiver is lesssensitive. Therefore, turn off thecircuit when its function is notrequired.2.9 Tuning the ReceiverThe receiver can be tuned automatically ormanually. For automatic tuning the receiveris tuned each time you switch from stand-by to transmit. For manual tuning, thereceiver is properly tuned when the longesttuning indicator appears. (However, thelength of the indicator changes with thenumber of radar echoes, range and otherfactors.) 1.5NM 0.5 AUTOTuningindicatorFigure 2-7 Tuning indicatorManual tuningThe default tuning method is automatic.

Count the number of rings betweenthe center of the display and the target.Check the range ring interval (at the top leftcorner) and judge the distance of the echofrom the inner edge of the nearest ring.By cursorOperate the omnipad to place the cursorintersection on the inside edge of the targetecho.

![2-8Tips for measuring the bearing•Bearing measurements of smallertargets are more accurate; the center oflarger target echoes is not as easilyidentified.•Bearings of stationary or slower movingtargets are more accurate than bearingsof faster moving targets.•To minimize bearing errors keep echoesin the outer half of the picture bychanging the range scale; angulardifference becomes difficult to resolveas a target approaches the center of thedisplay.Target on Collision course with your vessel?You can determine if a target might be on a collision course with your vessel by placing the EBL on the target. If it tracks along the EBL as it approaches the screen center it may be on a collision course with your vessel.2.12 Menu OperationThe menu, consisting of six sub menus,mostly contains less-often used functionswhich once preset do not require regularadjustment.

Press the [DISP MODE] and [HMOFF] keys together to select a presentationmode. Each time the keys are pressed, ifheading signal is input to the radar, thepresentation mode changes in thesequence of HU, CU (or WU), NU, TM. Ifthere is no heading signal input to the radar,the presentation mode is always HU.Note: TM does not function on the 48 nmrange.HU(head-up)CU(course-up)WPT-UP(waypoint-up)NU(north-up) TM(true motion)Selecting course-up mode for CUor WPT-UPYou may select WPT-UP instead of CU onthe menu.CU (course-up)An azimuth stabilized display in which aline connecting the center with the top ofthe display indicates own ship’s intendedcourse (namely, own ship’s previousheading just before this mode has beenselected).Target pips are painted at their measureddistances and in their directions relative tothe intended course which is maintained atthe 0-degree position while the headingline moves in accordance with ship’syawing and course change. This mode isuseful to avoid smearing of picture duringcourse change.WPT-UP (waypoint-up)An azimuth stabilized display in which theline connecting the center with the top ofthe display indicates the bearing to the“TO” waypoint, which is selected on thenavigational equipment connected to theradar. When navigating a route and ownship enters the arrival zone of a waypoint,the radar displays the bearing to the next“TO” waypoint.Procedure1. Press the [MENU] key to open themenu.2.

Press the [ENT] key followed by the[MENU] key.2.16 Guard AlarmThe guard alarm allows the operator to setthe desired range and bearing for a guardzone. When ships, islands, landmasses,etc. enter (or exit, depending on type ofguard zone in use) the guard zone anaudible alarm sounds to call the operator’sattention. The alarm is very effective as ananticollision aid when using an autopilot ornavigating in narrow channels.](https://usermanual.wiki/Furuno-USA/9ZWRTR065/User-Guide-107590-Page-21.png)
![2-13The guard alarm is a useful anti-collision aid, but does not relieve the operator of the responsibility to also keep a visual lookout for possible collision situations. The alarm should never be used as the sole means for detecting possible collision situations.CAUTIONSelecting guard zone typeThe guard alarm can be set to sound ontargets entering (guard in) or exiting (guardout) the guard zone.

If this happens, raise therange to redisplay the guard zone.•A target echo does not always mean alandmass, reef, ships or surface objectsbut can imply returns from sea surfaceor precipitation.

A barometer is built in thisradar; atmospheric pressure appears, ingraph form, on the navigation data displayduring stand-by. If your navigation aid canoutput data in NMEA 0183 data format,your vessel’s position in latitude andlongitude, the range and bearing towaypoint, speed, course, date, time andcross track error may be input to this radar,and be seen in the bottom text area duringstand-by. Further, with video sounder input,depth may be displayed, both digitally andin graph form.The barometer and depth displays are intended as reference. Any data displayed by them should be used with extreme caution.CAUTIONProcedure1. Press the [MENU] key.2. Press the omnipad at 6 o’clock toselect the Nav Data and press the[ENT] key.3.
