Alsocalled INTRODUCTION Welcome totheworld of sportfishlng sonar. Your Lowrance X-40 is ahighqualitysonardesigned forboth professionaland novice users.The findsand displays thebottomdepth,fish, and structure X-40automatically by justby turning it on. As you become familiarwith your X-40, try some of its remarkable features. "Fine tune" the unit to the surrounding to conditions getthe mostfrom your sonar. You can programtheX-40 to sound alarms whenthe boat goes shallower or deeperthan a presetdepth. An alarm will also soundwhena fish enters an alarm zone. Zoom in and separate fish from structure and each other. Only Lowrance gives you the power to adjust a sonar unit to its maximum potential. readtheinstallationsection. This TogetstartedwithyourX-40,first down iswhereit all begins, and improper installation can causeproblems theroad. Afteryou'vereadtheseinstructions and installedyour X-40, read the rest of this manual in detail. The more you knowwhen you getto the water, the moreyour X-40 will do foryou. Take this manual for reference whenyou head to thelake. INSTALLATION Mounting Install the X-40 in any convenient location, provided there is clearance whentiltedforthebestviewing angle. Holesinthe bracket base allow wood screw or through bolt mounting. Attach the bracket to aluminum panelswith sheet metal screws. Place apieceofplywood onthe back of thin fiberglass panels to secure the mountinghardware. Make certain there is enough room behind the unit to attach the power and transducer cables. "gain".

A measurement of frequency. Your Lowrance sonar operates at 192 Kilohertz. (192,000 cyclesper second). LCD-Liquid crystal display. Thescreenordisplay aLiquid Crystal Graph of sonar instrument. TheX-40 hasreverse polarityprotection. No damage will occur if thewiresare reversed. (However, theunitwill notwork until thewiresare attachedcorrectly.) LCG - Liquid Crystal Graph. NOISE - Any undesired signal. Electrical noise is caused by engine ignitions systems, radios, etc. Acoustic noiseis caused bythevibration of the engine or other mechanical sources. It appears on the display as random dots or lines. OPERATING FREQUENCY- Frequency that the sonar unit'stransmitter and receiverare tuned to. OUTPUT POWER-Theamplitude ofelectrical energytransmitted fromthe sonar unit to thetransducer. Measured in watts, the higher the output a power, thedeeper sonar unitcanread,and moredetailcan bedisplayed. PEAK-TO-PEAK 3-AMP - A measurementof the transmitter's poweroutput. PIXEL-The small dots or squares on a liquidcrystaldisplayor Crt. PIXELDENSITY -The number pixels per square inch on a liquid crystal of display. The bestresolution is obtained whena high number ofpixels are in the vertical. PULSE LENGTH - The amountof time that the sonar transmits. This is measured in micro-seconds. Theshorter the pulselength, the better the resolution. For example, a 30 micro-second pulselength is equal to a one inch resolution. RANGE - Thesectionofwatershown onthe sonar display.

Thealarm activates when the boat drifts into shallower or deeperwater than the alarm set points. Minimize electrical noise by routingthe power cable away from otherpossible sources ofelectrical interference. Oneofthelargestnoise generators is the engine'swiringharness that runs from the engine to the instrument panel. Thisharness usually containsawireforthe tachometer which radiates HF (radiofrequency) energy. For best results, keepthe power and transducer cables away from the engine wiring. Also, bilge pumpwiring cansometimes radiate noise so trytokeeptheX-40's cables awayfrom thosewires. byalight. BACKLIGHTEDAdisplayorkeyboardillUminatedfrombehitX1 Back-lighted displaysand keyboards are essential when night fishing or navigating. CAVITATION -Air bubbles created bythehighspeed movement ofa boat or transducer throughwater. VHFradio antenna cables radiate RFenergyathigherpowerlevels than eventhe engine'swiring harness. It is importantto keeptheX-40's power and transducercables as far away as possible from VHF radio cables. CHART SPEED -(1) The speed of the chart paper on a paper graph recorder. (2) Thespeed of an image acrossthe screen ofa liquid crystal graph. (Alsocalled "scroll speed"). CONE ANGLE-Width ofthe transducer's coneof sound. Lowrance has transducerswith coneanglesfrom 8to45degreestosuitthevaryingneeds offishermen. CRT -Abbreviation for Cathode RayTube. See VideoGraph. DEFINITION -The abilityof a sonar unit's displayto show detail. A high resolution displaycan show more detailthan a low resolution one. DISCRIMINATION -A featurethatallowsthe sonar toeliminate noiseand displayonlytruetargetinformation. Discrimination onLowrance products cuts outfalse signals from othersonar, noise, thermoclines, and more. FISH ALARM- An alarm that activates when a fish is detected. This noise is not electrical, but rather mechanically induced noise from the transducer. Stoptheboat, putthe engine in neutral, and increase the rpm. If the noise does not increase on the display, then it is cavitation. createacoustic of Usually, airbubblespassing overtheface thetransducer noise. Thefasteraboattravets, themoreairbubbles increaseand generate noise on the display. To eliminate this problem, read the transducer owner'smanual for propermounting techniques. If interference beginsat slowboat speeds, worsening astheboat speed increases, then a probable cause is acoustic noise, or cavitation. TRANSDUCER Installation instructions forthetransducer are withthetransducer in a separate package. Please read the instructions carefullybeforeyou install the transducer. FISHARCH - A sonar with good resolution displays fish signalswith an othertargets. upsidedown"V" orarch.
