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.

IMPORTANT SERVICE INFORMATION! If your unit is not working,or if you need technical help, please usethe followingtroubleshooting section before contactingthefactorycustomer servicedepartment. It may saveyou the trouble of returning your unit. Unit won't turn on: 1. Checkthe powercable'sconnection at the unit.Also checkthe wiring. 2. Make certain the powercableiswired properly. The red wire connects to the positive batteryterminal, blackto negative or ground. 3. Checkthefuse. 4. Measure the batteryvoltage atthe unit'spowerconnector.It should be at least 11 volts. If it isn't, the wiring to the unit is defective, the battery terminals or wiring on theterminals are corroded,or the battery needs charging. Unit freezes, locks up, or operates erratically: 1. Electrical noisefromtheboat's motor, trolling motor, or an accessory may be interfering with thesonar unit. Re-routing thepower and transducer cables away from other electrical wiring on the boat may help. Route the sonar unit's power cable directly to the battery instead of througha fuse blockor ignition switch 2. Inspectthetransducercablefor breaks, cuts, or pinched wires. 3. Checkboth the transducer and powerconnectors.Make certain both are securelyplugged in to the unit. Weak bottomecho, digital readings erratic,or no fish signals: 1. Makecertaintransducer is pointing straight down.Clean thefaceofthe transducer. Oil, dirt, and fuelcancause a film to formon thetransducer, reducingits effectiveness.

WINDOWS BAIT FISH The importance of baitfish to successful fishing can't be over-emphasized. They are the principle food of all game fish in mostwaters. Baitfisharethe plankton feeding foragefish, such as minnows and shad. Baitfishcanalso betheyoungofgamefish, suchascrappies, bluegill, and bass. Most bait fish concentrate within five feet of the surfacewhere sunlight promotes the growth ofthe plankton on which theyfeed. Onemethodof fishing isto usethe X-55to findthe baitfishfirst.

The easiestwayto dothison the X-55is with the Zoomfeature.This featureexpands the echoes,making it easierto see detail. For the bestresults, turn the sensitivityup as high as possible withoutgetting too much noise on the screen. In mediumto deep water,this method should work to displayfish arches. If yousee fish signalswhen the unit is in the manual mode, but don't get fish symbols whenthe Fish l.D.feature is on,tryincreasing thesensitivity. AND THERMOCLINES WATERTEMPERATURE Watertemperature hasan important-it not controlling-influence upon the activitiesofall fish. Fish are cold blooded and their bodiesare alwaysthe temperature of the surrounding water. During the winter, colderwater slows down their metabolism. At this time, they need about a fourth as much food as they consume in the summer. Mostfishdon'tspawn unlessthewatertemperature iswithin rather narrow limits. A surface temperature meter helps identifythe desired surface waterspawningtemperatures forvariousspecies. Troutcan'tsurvivein streams that get too warm. Bass and otherfish eventuallydie out when stocked in lakes that remaintoo cold duringthesummer. Whilesomefish tolerance thanothers,each hasacertain range have awidertemperature within whichit triesto stay. Schooling fish suspended over deep waterlie at the level that provides thistemperature. We assume theyarethe most comfortable here. VIEWING WINDOWS OPTIONS To seeall of the available window options, press the WINDOWS key, then press the MENU key.

MODIFYING GROUPS The temperature of water in the lake is seldom constant from top to bottom. Layers of different temperatures form,andthejunctionofawarm and cool layerof water is called a thermocline. The depth and thickness ofthethermoclinecan varywiththeseason ortime of day. In deep lakes theremaybetwo or moreat different depths. Thermoclines are important to fishermenbecause they are areas wherefish are active. Manytimes baitfish will be abovethethermocline while largergame fish will suspend in or just below it.

Thisallowsyoutoviewall incoming echoesbefore theyare processed by the ASPfeature. The sensitivity key on theX-55 controls the ability of the unitto pick up echoes. A low sensitivity level excludes much ofthe bottom information, fish signals, and othertarget information. High sensitivity levels enables youtoseethisdetail,but itcanalso clutterthescreen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Graylineand somesurfaceclutter. Whenthe X-55 is in the Automaticmode,thesensitivity is automatically adjustedto keep a solid bottom signal displayed, plus a little more. This gives it thecapabilityto showfish and other detail. However,situations occur where it becomes necessary to increase or decreasethe sensitivity. This typically happens when you wish to see more detail, so an increase in sensitivity is indicated. The procedureto adjust it isthesamewhethertheunitis in the automatic or manual mode. Toadjustthe sensitivity, presstheSENSkey. Thesensitivity adjustmenu appearsat thebottom of the screen.

Then press the key nextto the "ADJUST LEVELOF CHARTASP" labeluntil the desired level is obtained. SIGNAL INTERPRETATION Your X-55 gives an accurate picture of the bottom that your boat is passing. A bottom of firm sand, gravel, shell, or hard clay returns a fairly widesignal. Ifthe automatic mode isoff and thesignal narrows down,then it means thatyouhave moved overa mud bottom. Mud absorbsthesound wave and returns a weaksignal. Turn up the sensitivity to see a better bottom signal. Big rocks or stumps on a smooth bottom send back signals above the bottom level signal. The height of the signal depends on the target's height. Asyou passover apost, it shouldbe clearly visibleas ashort line extending abovethe bottomsignal. A steep slope returns a wide signal, the steeper the wider. Signals returned from a high underwater cliff are usuallythe widestof all. When the Fish ID. mode is off, the depth of the water will affectthe size and shapeofthe fish arch due to the coneanglediameter. For example, ifthe conepassesoverafish inshallowwater,the signal displayed on the X-55 maynot arch at all. Thisis due tothenarrowconediameter and the resolution limitations of the display. To decreasethe sensitivity level, press the key adjacent to the leftarrow. The bargraph and percentage will decrease. Whenthe sensitivity is atthe desired level, release the key. Whenyou reach either the maximum or minimum limit, a tone sounds.

ADJUST CHARTSURFACE CLARITY Themarkings extending downward from the zero line on the chart are called "surfaceclutter." These markings are caused by wave action, boat wakes, temperature inversion, and othernatural causes. RANGE- Automatic When turned onforthefirsttime,theX-S5automatically placesthebottom signal in the lower half of the screen. This is called Auto Ranging and is part of the automatic function. The range cannot be changedmanually whilethe unit is in automatic. RANGE- Manual The X-55givesyoucontrol overthe range when it's inthe manual mode. Tochange therange,firstmake certaintheX-55 isinthemanual mode. Next, presstheRANGE key. The range adjustment menu appearsinthe lowerright cornerofthe display. Pressthe up or down arrow keys to decrease or increase the range. The available range.s are 0-5, 10, 20, 30, 40, 60, 100, 150, 200, 300, 500, 800, and 1000 feet. After the desired rangeis displayed, press the CLEAR key to erase the rangemenu. TheSurfaceClarityControl (5CC) reduces or eliminates surface clutter signals from the display. 3CC varies the sensitivity of the receiver, decreasing it nearthe surface and gradually increasing it as the depth increases. Themaximum depth that5CCwill affect is75%oftheselected depth range. For example, on a 0-60 foot range with maximum 8CC, surface clutter will be reduced down to 45 feet. There are three levels of 8CC available on the X-55: low, medium, and high. When it'sturnedon forthe firsttime,the8CC level is low. To change it, press the MENU key five times, then press the key adjacent to the "ADJUST CHARTSURFACE CLARITY" label until the black boxisonthe desired 3CC level. Press the key nextto the "EXIT" label when you're finished. 9&3FTks
