Using menufeaturesand "soft-key"operation, the X-55 is also one of the easiest-to-use sonars that Lowrancehasever high built.Thewide"Clearvision"screen showstheunderwaterworldwith resolution and detail. Thedisplayand keyboard are also lighted for night operation. The X-55 also has digital depth, boat speed, surface water temperature,and distancetravelled (log) displays. In order to use the digital speed, temperature,and log displays, you must purchase and install an optional ST-T (transom mount) or ST-H (through-hull mount) speed/temperature sensor. turned off. j,o tbm An--r 36.5 ETIWI DEPTH rFEET I fl1DIM I MPH !M I I Readthis manual and takeitwith youthefirstfewtimes youuseyour unit.

For the bestresults, attach the powercable directlyto the battery. You can attachthe power cable to an accessoryor power buss, howeveryou may have problems with electrical interference. Therefore, itssaferto goaheadand attach the powercable directlyto the battery. If thecable is not long enough, splice #18 gaugewireontoit.Thepowercablehastwowires, red and black. Red is the positivelead, blackis negative or ground. Make certain to attach the in-linefuseholdertothe red leadas closetothepowersourceas possible. Forexample,ifyouhavetoextendthe powercable thebattery orpower to buss, attach one end of the fuse holder directlyto the batteryor power buss.This will protectboth the unitand the powercable in the eventof a short. The X-55 uses a 3-amp fuse. IMPORTANT! NOISE A major causeofsonarproblems is electrical noise. This usuallyappears onthe sonar'sdisplayas random patterns ofdotsorlines.In severe cases, it can completely cover the screen with black dots, or cause the unit operate erraticly, or not at all. Do notusethisproductwithouta 3-ampfuse wired intothe powercable! Failure to usea 3-amp fusewill void your warranty. temperature sensor's installation manual for mounting instructions. Route the sensor's cableto the X-55's power cable and plug it into the connector marked "SPEED/TEMP CABLE" To eliminate or minimize the effects of electrical noise, first try to determine the cause. Withthe boat at rest in the water, the firstthingyou shoulddo isturn all electrical equipment onthe boatoff. Make certain the engineisoff, also.Turnyour X-55on, then turnoffASP (Advanced Signal Processing). Thereshould be a steady bottom signal on the display. Now turn on eachpiece of electrical equipment on the boat andviewtheeffect on the sonar'sdisplay. For example, turnon the bilge pump and viewthe sonardisplayfor noise. If no noiseis present, turnthepump off, thenturn on the VHF radio and transmit. Keep doing this until all electrical equipmenthas been turned on, their effect on the sonar display noted, then turned off. pump, or radio, try to isolate the problem. You can usually re-route the sonar unit's powercableand transducer cableawayfrom the wiring that iscausingthe interference. VHFradio antennacables radiatenoisewhen transmitting, so becertain to keep thesonar'swires awayfromit.You may need to routethe sonar unit'spowercabledirectlytothe batteryto isolate it from otherwiring on the boat. Ifyou'reinstalling an optional speed/temperature sensor, readthespeed/ If youfind noiseinterference froman electrical instrument, trollingmotor, FlED 3amp FUSE certain everythingexceptthesonarunitisturned then starttheengine. off, Increasethe RPM with the gearshift in neutral. If noise appears on the display, the problem could be one ofthreethings; sparkplugs, alternator, or tachometer wiring. Try using resistor spark plugs, alternator filters, or routing the sonar unit's power cable away from engine wiring. Again, routing the power cable directly to the battery helps eliminate noise problems. Make certain to usethe in-line fusesupplied with the unitwhen wiring the powercable to the battery. When no noise appears on the sonar unitafterall ofthe abovetests, then the noise source is probably cavitation. Many novices or personswith limited experiencemake hastysonarinstallations whichfunction perfectly in shallowwater, orwhenthe boat is at rest. In nearlyall cases, thecause ofthemalfunction will be the location and/orangleof the transducer. The faceofthe transducermustbe placed ina location that hasa smooth flow ofwaterat all boat speeds.

If the sonar can'tfindthebottom signal while it's in the automatic mode, the digital willflash continuously. It may change therangeto limitsfar greater than the water you are in. If this happens, place the unit in the manual mode,then changetherange to a realistic one, (for example, 0-100feet) and increase the sensitivity. As you move intoshallowerwater,a bottom signal shouldappear. TRANSDUCER CONNECTIONS See the transducerowner's manual included with the unitfor complete transducerinstallation instructions. SIDESCAN TheX-55 hasoptionalside-scancapability. To usethis feature,youmust purchase the ScanPac accessory. To install it, follow the instructions enclosedwith the ScanPac. See the"Side ScanOperation" section in thismanual for information on using the side-scan feature. SPEED/TEMPERATURE/DISTANCE LOG 4. Check the batteryvoltage. If thevoltage drops, the unit's transmitter poweralso drops, reducing its abilityto find thebottom or targets. Bottom echodisappears at highspeeds or erratic digital reading or weak bottomecho while boat is moving 1. The transducer may be in turbulent water. It must be mounted in a smooth flow of waterin orderfor the sonarto workat all boatspeeds. Air bubbles inthe waterdisrupt the sonarsignals, interfering with itsabilityto findthebottom or othertargets. The technical term for this is Cavitation. 2. Electrical noisefromthe boat's motorcan interfere with thesonar. This causes the sonar to automatically increase its Discrimination or noise such rejectionfeature. Thiscancausetheunittoeliminateweakersignals structure fromthe display. Try using resistorspark plugs as fish or even or routingthe sonar unit'spower and transducer cables awayfrom other electrical wiring on the boat. No fish arches when the Fish ID feature is off: 1. Make certain transduceris pointing straight down. This is the most commonproblem if a partial arch is displayed. See theFishArch section in your owner's manual for more information. 2. The sensitivity maynot be high enough. In orderfor the unitto display afish arch, it hastobe ableto receive thefish'sechofromthetimeitenters the cone until it leaves. If the sensitivity is not high enough, the unit displays the fish only when it is in the center of the cone. To usethespeed, temperature, and distance log features, youmustinstall an optional speed/temperature sensor. Lowrance manufactures a thruhull sensor/transducer combination unit and a transom mount speed/ sensor. temp only Thekeyboardhaskeys arranged intwoverticalcolumnsplus ahorizontal row at the bottom.

KEYBOARD RANGE- Thiskey lets youadjustthe range whenthe unitis inthemanual mode. ZOOM - The X-55 gives you 2X and 4X zoom capabilitywith this key. 3. Use the Zoom feature. It is much easierto display fish arches when zoomedin on a small range of waterthan a large one. For example, you will have much better luck seeing fish arches with a 30 to 60 foot range than a 0 to 60 foot range. Thisenlargesthe targets,allowing thedisplay to show much more detail. 4. The boat must be moving at a slow trolling speed to see fish arches. If the boat is motionless, fish stay in the cone, showing on the display as straighthorizontal lines. 34 AUTO - This turns the automatic feature off and on.
