TABLE OF CONTENTS TRANSDUCER -The element of a sonar system that convertsthe electrical energy from the transmitter Into ultrasonic sound waves. When a return echo strikes the transducer, it converts the sound waves into electrical POWER CONNECTIONS 2 energy which is received and displayed by the sonar unit.

A remote doesn't have a transmitter or receiver. However, it does have ft's own features that are adjustable and operate separately from the master[...]

Power Connections TheX-40 operates from a 12 volt battery system. Attach the power cable to an accessory or power buss. If you have problems with electrical interference, then attach the cable directly to the battery. Electrical Interference shows as random dots on the display whenever the boat's engine or an accessory is on. The power cable h[...]

KEYBOARD BASICS This section gives a brief explanation of the keyboard. Read the Operation section for a detailed description of each key's operation. GRAYLINE SET Press this key to adjust the grayline level. DIGITAL SONAR The X-40 is really two sonars in one housing. The mostobvious is the graph, designed to show all return echoes. The other [...]

BAIT FISH The importance of bait fish to successful fishing can't be over- emphasized. They are the principle food of all game fish In most waters. Baitfish arethe planktonfeeding foragefish, suchas minnows and shad. Bait fish can also be the young of game fish, such as crappies, bluegill, and bass. Most bait fish concentrate within five feet [...]

DISPLAY INTERPRETATION Now let's look at the display. First, we'll turn on the X-40 by pressing the ON key. The lights will flash for six seconds. The chart scrolls the return echoes across the screen and the digital searches for the bottom depth. It's flashes 0 untIl it finds the bottom. Once it finds the bottom, the depth is displa[...]

Mostfish don'tspawn unlessthewatertemperature iswithin rather narrow limits. To find the different temperatures, a surface temperature meter, such as the LDT-3000 is a valuable aid to your boat. This unit provides an extremely quick response to identifying the desired surface water spawning temperatures for various species. Trout can't su[...]

11/Vs AUTO When the horizontal bar reaches the far right hand side of the screen, the sensitivity level is at maximum. With high sensitMty settings, a second bottom echo (second echo) may appear. This is normal. It's caused by the returning signal reflecting off the surface of the water. Then it makes a second trip to the bottom and back again[...]

pick upthe bottom signal, then add in the level you programmed. If desired, you can add sensitivity up to the maximum. To adjust the sensitivity while the X-40 is in the automatic mode, simply press the right arrow key to increase it. Press the left arrow key to decrease the sensitivity. As you press the arrow key, the sensitivity barwill move righ[...]

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 aflashlight. The angle between the outside edges of the cone is the cone angle. Lowrance offers a choice of transducers with either an 8 or 20 degree cone angle. These will interchange with any of the 1[...]

LOWER LOWER LIMIT LIMIT To change the lower limit, first make certain the word "AUTO" Is off at thetop ofthescreen. Thisindicatesthat the automatic mode is off. (Note: This also disables the automatic sensitivity function.) If the automatic mode is on, press the AUTO key once to disable It. Next, pressthe lower limitdesired from 10 to 999[...]

121 0 t J PULSE PULSE There isa relationship between resolution and transmitter pulse length. Resolution, in this case, is the ability of a C sonar to separate targets. The shorter the pulse length, the better the sonar's — ability to separate targets. However, in deep water, the shorter the pulse length, the less likely a return echo will b[...]
