- LCD Liquidcrystal display. The screen or display of a Liquid Crystal Graph sonar instrument. LCG - Liquid Crystal Graph. - NOISE Any undesired signal. Electrical noise is caused by engine ignitions systems, radios, etc. Acoustic noise is causedby the vibration of the engine or other mechanical sources. Noise appears on the displayas random dots or lines. OPERATING FREQUENCY- Frequency of a sonar unit's transmitter and receiver. (See kHz.
Electrical interference shows as random dots on the display whenever the boat's engineor an accessory is on. The power cable has two wires, red is the positive lead and black is negative or ground. Attachthe in-linefuse holderto the red wire on the powercable with thecrimpconnector. The other end ofthefuseholder attaches to the battery or accessory buss. If the cable is not long enough, spliceordinary#18 gauge wire onto it.

BAIT FISH The importance of bait fish to successful fishina can't be over-emohasized. They are the principalfood of all game fish in mostwaters. Bait fish are the plankton feeding forage fish, such as minnows and shad. Bait fish can also be the young of game fish, such as crappies, bluegill, and bass. Most bali fish concentratewithin five feet of thesurface where sunlight promotesthegrowth of the plankton on which theyfeed. One method of fishing is to usethe unitto find the baitfish first.
stay. Schooling fish suspended over deep water lie at the level that provides this temperature. We assumethey are the most comfortable here. The temperature of water in the lake is seldom constant from top to bottom. Layers of different temperatures form, and the junction of a warm and cool layer of water is called a thermocline. The depth and thickness ofthe thermocline can vary with the seasonor time of day. In deep lakes there maybe two or moreat differentdepths.
WATERTEMPERATUREAND THERMOCLINES Water temperature has an important-if not controlling-influence upon the activities of all fish. Fish are cold blooded and their bodies are always the temperatureof the surrounding water. During the winter, colder water slows down their metabolism. At this time, they need about a fourth as muchfood as they consume in the summer. Most fish don't spawn unless the water temperature is within rather narrow limits. The surface temperature meterbuilt into the Fish l.D.
BOATS DIRECTION OF TRAVEL OPERATION SENSITIVITY Theunit is in the AUTO SEARCH mode when ft's first turned on. The micro-computer automatically adjuststhe sensitivity and range to find and lock onto thebottom. The digitaldepth flashes"0" until it finds and locks onto the bottom. You can leave the sensitivity in the automatic mode or manually adjust it to suit conditions. You mayneed to increase thesensitivity to showfish symbols when the unit is in automatic. To do this, first pressthe SENS. key.
With highsensitivity settings,a second bottomecho (secondecho) may appear. This is normal. It'scaused by the returning signal reflecting off the surface of thewater. Then it makes a second trip to the bottom and back again. Both 8 degree and 20 degreetransducers give accurate bottom readings, even though the bottom signal is much wider on the 20 degree model. This is because you are seeing more of the bottom. Remember, the shallowedge of the signalshowsyou the true depth.
TRANSDUCERS AND CONE ANGLES The sound waves from the transducer spread out into the water in a cone shaped beam. This looks much like the beam from a flashlight. The angle between theoutside edges of the cone is the coneangle. Eagleoffers a choiceof transducers with either an 8 or 20 degreecone angle. Typically, wide cone angle transducers (20 degrees) are ideal for operating in shallow to medium water depths. The 20 degree cone angle allows you to see more of the underwater world.
RANGE The range automatically changes to keep the bottom signal on the display when the unit is in automatic. The range cannot be changed when the unit is in the automatic mode. The range can be changed in manual mode. There are six ranges available:0-5, 15, 30, 60, 120, and 180 feet. To changetherange, first make certainthewordAUTO is off. Then press the RANGE key. The word RANGEwill flash on the right side of the screen.
ZOOM- Manual Mode Zoom operates differently when the unit is in the manual mode. First presstheZOOM key. The bottomhalf of the range is enlarged, just like the automatic zoom feature. However, if you press an arrow key, the range shifts in one foot increments. The down arrow key to shiftsthe range down in one toot increments. The up arrow keyshifts the range up in one foot increments.
FISHI.D. The Fish I.D. featureis automatically on when theunit is first turned on. The computerinsidethe unitanalyzes all echoes,filteringoutunwanted signals. It helps eliminatesurface clutter, thermoclines,and other undesirable signals. The remaining suspended targets are usually fish. Targets that are identified by the unit as fish are displayed as small, medium, or large fish symbols on the display. These symbols are shownaccording to therelative size ofthefish as seenby theunit. The Fish l.D.
MODE The Fish I.D. hasfive differentscreen modes. The Fish I.D. Plus has seven. To change modes on both units, press the MODE key. Keep pressingthe MODE key until the desired screen appears. A summary of the differentscreen modes follows. - Fishl.D.andl.D. This is the default Plus when the unit is mode used on. It has thefolfirst turned lowingfeatures: MODE 1 - Mi(FO.

CHART ALARM To setthe ChartAlarm, press the CHARTALARMkey on the keyboard. The words "Chart Alarm"flashesin thelower right cornerofthescreen. A verticalbar also displays on the left side of the screen. It will stay on the screen foreight seconds or foreight seconds afteryou havefinished adjustingit. This is theChart Alarm's "window."Any echothat appears between the top and bottom of this bar will sound the alarm. Adjust deep end of thisbar to make a smalleror largeralarm "window.
