SONAR TABLE OF CONTENTS INTRODUCTION ................................................................................................................... ......... 1 MOUNTING .............................................................................
.
1 FRONT SLOT BREAK OUT SLOT You will need to drill a hole in the dash for the power and transducer cables. The smallest hole that will pass one power or transducer plug is one inch. After the hole is drilled, pass the transducer connector up through the hole first, then pass the power cable down through it.
2 IN-DASH MOUNTING The LMS-350A can be installed in the dash with the supplied hardware if the dash is 1/2" thick or less. Determining the dash thickness can be difficult, however, if you remove a gauge from the dash, you can easilly measure the thickness.
3 POWER CONNECTIONS The LMS-350A works from a twelve-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference.
4 50 kHz TRANSDUCER 192 kHz TRANSDUCER TRANSDUCER ADAPTER CABLE (MY-2) The white wire is for a NMEA interface. The LMS-350A sends data to another electronic navigation devices through the white wire. It receives data from a differential (DGPS) beacon receiver through the green wire.
5 OPTIONAL GPS MODULE INSTALLATION The GPS module can be installed on a flat surface or (with the supplied adapter) on a pole. Mount the module in an area that guarantees a clear view of the sky at all times. In order for the module to receive the signals from the satellites, it must not be obstructed.
6 Surface Mounting - Without Access If you don't have access to the back side of the mounting surface, use the "cleats" supplied with the LMS-350A. (Note: This is assuming you can "snake" the module's cable to a location that is accessable.
7 Pole Mount First, thread the pole mounting adapter onto the mounting pole or ratchet base. Align the pole mounting adapter so the module will face the bow of the boat. Install and tighten the set screw into the pole mounting adapter and tighten it securely.

9 WAYPT QUICK SAVE - Pressing this key instantly saves your position. MENU - Press this key to show the menus and gain access to most functions. CLR - This key clears menus and erases entries from the screen. ENT - This key is used to enter numbers and make selections.
10 WINDOWS You can change the displays on the LMS-350A by using the windows feature. This lets you customize displays to your own fishing or boating situations. This feature gives you 22 different window screens. The screens available in the windows mode are divided into two or more windows per screen.
11 To use the windows feature, first press the WINDOWS key. A screen similar to the one shown at left appears. The menu on the right side of the screen lets you switch between the “pages” of displays. These are lettered “A” through “V”. Group “A” shows first.
12 press the CLR key. VIEWING WINDOWS OPTIONS To see all of the available win- dow options, press the WIN- DOWS key, then press the MENU key. Now press the key adjacent to the “MAIN MENU” label. Finally, press the key next to the “VIEW ALL WIN- DOWS” label.
13 next to the “GROUP A” label was pressed. The screen shown at the top of the next page appears. The depth window appears in the upper right corner of the screen.
14 AUTOMATIC When the LMS-350A is first turned on, the Automatic fea- ture is enabled. This is indi- cated by the word “AUTO” at the top of the screen. The Auto- matic feature adjusts the sensi- tivity and range so the bottom signal is displayed in the lower half of the screen at all times.
15 SENSITIVITY The sensitivity key on the LMS-350A controls the ability of the unit to pick up echoes. A low sensitivity level excludes much of the bottom informa- tion, fish signals, and other target information. High sensitivity levels enables you to see this detail, but it can also clutter the screen with many undesired signals.
16 RANGE - Automatic When turned on for the first time, the LMS-350A automatically places the bottom signal in the lower half of the screen. This is called Auto Ranging and is part of the automatic function. The range cannot be changed manually while the unit is in automatic.
17 ZOOM Enlarging or “zooming” the picture is a common method used to show small detail and fish signals. The LMS-350A gives you two different zoom sizes, plus a split screen zoom option. The zoom operation and adjust- ment is different in the automatic and manual modes.
18 next to the “RESET ALL GROUPS” label. Turn the zoom feature on (or off) by pressing the key adja- cent to the “OFF/ON” label. Pressing the key adjacent to the “2X/4X” label enlarges ech- oes from two times to four times their normal size.
19 the bottom when it’s in the manual mode. MENU - PAGE 1 CHART SPEED The rate echoes scroll across the screen is called the chart speed. It’s adjustable by first pressing the menu key, then pressing the key adjacent to the “Adjust Chart Speed” label.
20 GRAYLINE ® OFF GRAYLINE ® ON GRAYLINE is adjustable. Since GRAYLINE shows the difference be- tween strong and weak signals, adjusting the sensitivity may require a different GRAYLINE level, also. The level chosen by the LMS-350A at power on is usually adequate for most conditions.
21 The micro-computer is sophisticated, but it can be fooled. It cannot distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending DISPLAY CONTRAST The unit’s display contrast is adjustable to suit different lighting conditions.
22 ALARMS The LMS-350A has three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines an echo or group of echoes is a fish. Another alarm is the Zone Alarm which consists of a bar. Any echo that appears inside this bar triggers the alarm.
23 DEPTH ALARMS The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm’s setting or deeper than the deep alarm’s setting. For example, if you set the shallow alarm to ten feet, the alarm will sound a tone if the bottom sig- nal is less than ten feet.
24 ZONE ALARM The zone alarm consists of a bar that appears on the right side of the screen. Any echo that appears on the screen between the top and bottom of the zone alarm’s bar will “trip” the zone alarm. Note: The zone alarm isn't available in the Windows mode.
25 SONAR FREQUENCY The LMS-350A operates from 50 or 192 kHz, either inde- pendently or simultaneously. The sonar unit comes with a 192 kHz transducer, other op- tional transducers are avail- able. See the transducer dia- gram on page 3 for single or dual transducer connections.
26 50 kHz 192 kHz CHART DUAL FREQUENCY OPERATION Sensitivity and Grayline ® adjust differently when the Dual Frequency feature is enabled. The LMS-350A lets you make changes to the sensitivity and Grayline on one side of the screen without affecting the other.
27 pressed. The bar chart also gives a graphical indication of the contrast level. You can see the change on the screen as you press the keys. After you’ve made the adjustment, press the CLR key to erase the menu. MENU - PAGE 2 ADJUST BACK LIGHT LEVEL The LMS-350A has internal lights for the display and keyboard.
28 TURN DIGITAL INSTRUMENT BOX OFF The digital box is displayed in the upper left corner of the full sonar screen. It has the digital depth and automatic/manual indicators. To turn this box off, press the MENU key then the key next to the "More" label, then the key adjacent to the “TURN DIGITAL INSTRUMENT BOX OFF” label.
29 label. Finally, press the key next to the “Turn Backlight On Off” label. This moves the black box from “OFF” to the “ON” position. To turn the backlights off, repeat the same steps. MENU - PAGE 3 DISPLAY ZOOM BAR When the unit is in the zoom mode, the zoom bar doesn’t normally show on the screen.
30 sonar screen as shown at right. This turns the zone alarm on at the same time. To turn the zone bar off, repeat the above steps, until the third menu page appears, then press the key adjacent to the “Re- move Zone Bar” label.
31 press the up or down arrow keys. This lets you move the cursor to verify a target's depth. To turn the chart cursor off, press the MENU key until the third menu screen appears. Now press the key next to the "Turn Chart Cursor Off" label.
32 SELECT UNITS OF MEA- SURE The LMS-350A can display the water depth in feet, fathoms, or meters, surface water tempera- ture in degrees Fahrenheit or Celsius, speed in statute miles per hour, kilometers per hour, or knots, and distance (log) in miles, kilometers, or nautical miles.
33 MENU - PAGE 5 ADJUST CHART SURFACE CLARITY The markings extending down- ward from the zero line on the chart are called “surface clut- ter.” These markings are caused by wave action, boat wakes, temperature inversion, and other natural causes. The Surface Clarity Control (SCC) reduces or eliminates surface clutter signals from the display.
34 ASP (Advanced Signal Processing) The ASP feature is a noise rejection system built into the LMS-350A that constantly evaluates the effects of boat speed, water conditions, and interference. This automatic feature gives you the best dis- play possible under most con- ditions.
35 PRESET SONAR AND GPS The LMS-350A has a built-in memory that saves all settings such as sensitivity, chart speed, keel offset, speed calibration, and more. Virtually all settings except for waypoint and route information is saved in this memory. (Waypoints, icons, and routes are saved in a separate memory.
36 IMPORTANT! The digital depth display is the only sonar that is affected by the keel offset feature! The chart will always show the distance from the face of the transducer. To adjust the keel offset, first press the MENU key then press the key next to the "More" label until the sixth menu page appears.
37 Your current boat speed and distance log are shown in the upper left coner of the screen. The calibration in percent is shown in the upper right cor- ner. Now enter the percent change that is needed to make the LMS-350's speed display match your actual speed.
38 that this doesn't turn the zone alarm off. See the Alarms section for more information on the zone alarm. TRANSDUCER 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.
39 A BC BOAT'S DIRECTION OF TRAVEL A B C Both 8 degree and 20 degree transducers 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 shallow edge of the signal shows you the true depth.
40 partial arch, or a shape similar to an arch if they’re in deep water. Large fish will arch, but turn the sensitivity up in deeper water to see the arch. Because of water conditions, such as heavy surface clutter, thermoclines, etc., the sensitivity sometimes cannot be increased enough to get fish arches.
41 the sonar unit’s power cable directly to the battery instead of through a fuse block or ignition switch 2. Inspect the transducer cable for breaks, cuts, or pinched wires. 3. Check both the transducer and power connectors. Make certain both are securely plugged in to the unit.
42 as fish or even structure from the display. Try using resistor spark plugs or routing the sonar unit’s power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish ID feature is off: 1. Make certain transducer is pointing straight down.
43 is causing the interference. VHF radio antenna cables radiate noise when transmitting, so be certain to keep the sonar’s wires away from it. You may need to route the sonar unit’s power cable directly to the battery to isolate it from other wiring on the boat.

52 GPS TABLE OF CONTENTS GPS - HOW IT WORKS .................................................................................................................. 5 3 ACCURACY ...............................................................................
53 GPS - HOW IT WORKS The Global Positioning System (GPS) is the best approach to navigation that has ever been devised. Conceived by the Department of Defense (DOD) and the United States military, the GPS system is an answer to their needs of 24 hour global positioning, 365 days a year.
54 ACCURACY You may have heard tales of extraordinary accuracy from GPS receivers. The DOD requires accuracy of 10 to 15 meters from the satellite system. However, only the military gets this precision. The way the military keeps us and other unauthorized people from using the more precise system is coding.
55 GETTING STARTED Initialization - Power On In order for the LMS-350A to lock onto the satellites, it must first find them. If you simply turn the unit on and wait, the unit will find the satellites by itself in 15 minutes or less. This is called “Cold Start.
56 Note: If you don’t use the “cold start” feature, then you will have to change all of the settings on this page to their correct values. In other words, you can’t simply enter your present position and have the unit find the correct values by itself.
57 below sea level. You would need to enter the numbers “35”, then press the key next to the "Altitude + -" label to change it to -35 feet.
58 If the unit can’t lock on to the satellites using the data you’ve given it, or if it has trouble finding the satellites, perhaps it is using the wrong data. This can happen if you’ve entered the wrong data by accident. For example, given it east longitude instead of west.
59 The LMS-350A has a five chan- nel GPS receiver. Data on each channel is shown at the top of the display. The channels are numbered one through five on the left side of the screen. Ev- ery satellite in the constellation has a number assigned to it, called the PRN.
60 (COG), Distance To Go (DTG) to waypoint, Bearing to way- point, Time To Go (TTG) to waypoint, and local time and date displays at the bottom of the screen. Your present position shows at the top of the screen in latitude/ longitude coordinates. This is shown in degrees, minutes, and thousandths of a minute.
61 a black box surrounding them, then the distance markers is showing the distance PAST the waypoint. In other words, if the numbers are sur- rounded by a black box, then you have passed the waypoint and need to turn around. The numbers immediately below the CDI are the CDI range in miles.
62 In this example, we changed the Speed Over Ground (SOG) display to XTE (Cross Track Error) by pressing the up arrow key eight times. To change another digital dis- play, press the left or right ar- row key. The label in the next digital display box changes as you press the arrow key.
63 The flashing cross is your present position. The solid line is your track, or path you have just traveled. The large square is a compass rose marked with North, South, East, and West. The square’s height and width shows at the bottom of the screen.
64 cursor position, distance, and bearing displays at the top of the screen. PLOTTING WITH A WAY- POINT Using the plotter with a recalled waypoint or route is an easy way to see the effects of wind and current on your boat. It also simplifies navigation.
65 SET RANGE Use the "Set Range" menu to change the plotter’s range or distance across the plotter’s display. The range is 1 statute mile when the LMS-350A is turned on for the first time. The available plotter ranges are .1, .2, .5, 1, 2, 5, 10, 20, 50, and 100 miles.
66 When you're finished, press the CLR key to exit. PLOTTER MENU -PAGE 2 GOTO CURSOR As mentioned previously, t he cursor lines can be used to place an icon or highlight a position. When you use the cursor lines, the position of the cross hairs on the display are shown at the top of the screen.
67 To use this feature, first move the cursor lines to the desired location on the plotter screen. Next, press the MENU key. Now press the key adjacent to the "More" label. Finally, press the key next to the “Go To User Cursor” label. The unit returns to the plotter screen.
68 SELECT UNITS OF MEASURE The LMS-350A can display dis- tance in miles, kilometers, or nautical miles, velocity in miles per hour, kilometers per hour, or knots, bearing in degrees magnetic or true, altitude in feet or meters, and time in 12 hour or 24 hour format.
69 EVENT MARKER The LMS-350A can place event markers or “icons” on the plot- ter to mark fishing spots, shal- low water, or other special lo- cations. There are five different icons to choose from and there are 100 of each icon for a total of 500.
70 ing the arrow keys. When it’s at the desired location, press the EVENT MARKER key, then select an icon. The LMS-350A places the icon at the intersection of the plotter cursor lines. To erase the cursor lines, press the CLEAR key. Erasing the Icons Although you can place icons on the plotter individually, you can’t erase them one at a time.
71 (Quick Save Feature) The LMS-350A lets you save your present position as a waypoint with only one key press. This “Quick Save” feature lets you easily save the position of a wreck or other locations. To save your present position as waypoint, simply press the WAYPT QUICKSAVE key.
72 the last used position, plotter, or steering screen. Enter New Waypoint To save a location other than your present position, first press the WAYPT key, then press the key next to the "WPT Save" label. Using the up and down arrow keys, move the black box down to the latitude/longitude position.
73 shown above appears. Use the keys on both sides of the screen to enter the way- point name. For example, to name a waypoint “COVE 1”, press the ALARM key repeat- edly until the letter “C” appears in the window. Next, press the right arrow key to move the black box to the next letter po- sition.
74 next page appears. Now press the key next to the “Increase WPT” or “Decrease WPT” label until the desired waypoint number appears on the screen. Or simply enter the waypoint number using the numbered keys. When it does, simply press the key next to the “Go to Waypoint” label.
75 pressing the key next to the "Increase" or "Decrease" RTE# labels. When the desired number appears, you can create or edit it. Name a Route To assign a name to a route, press the key next to the “Increase RTE#” or “Decrease RTE#” label to move through the list of routes.
76 the second waypoint line. Now enter the waypoint number for the second waypoint in the route. Press the key next to the "Accept" label. Continue entering the waypoints until all of the waypoints have been entered for the route. Then press the key next to the “Save RTE” label.
77 waypoint in the route, the arrival alarm sounds until you turn it off. IMPORTANT! Turning the arrival alarm off prevents the LMS-350A from sequencing to the next waypoint in the route.
78 as shown above. Now press the key next to the “Increase RTE#” or “Decrease RTE#” labels to cycle through the available routes. After you’ve selected the desired route, press the key next to the “ERASE RTE” label. This erases the route from memory.
79 The following section describes each GPS alarm and its limits. ARRIVAL ALARM The arrival alarm sounds a tone when your position is within the alarm’s radius of a waypoint. For example, the alarm sounds if you come within .1 mile of a recalled waypoint if the arrival alarm’s setting is .
80 SELECT NMEA The LMS-350A sends data out the white wire on the power cable according to standards set by the NMEA (National Marine Electronics Association). This allows the LMS-350A to send position, depth, and navigation information to “listener” units, such as charting instruments, autopilots, and other marine instruments.
81 DGPS (Differential GPS) BEACON RECEIVER SETUP You'll have to tell the LMS-350A which beacon receiver's data to expect and set up the parameters for that data. To do this, first press the MENU key, then press the key next to the "Change GPS Settings" label.
82 This page shows the station ID number, its frequency and bit rate, the "health" of the station (0 = best, 5 = worst), signal strength (the higher the num- ber, the better), and the signal- to-noise ratio (SNR). The high- er the SNR number, the better.
83 MAN OVERBOARD One of boating’s most terrifying events is having a friend or family member fall overboard. This situation can be deadly on any body of water, fresh or salt. It’s particularly dangerous at night or if you’re out of sight of land.
84 The LMS-350A doesn't save the Man Overboard position in the waypoint table. However, it does save the position on the Man Overboard screen. The LMS-350A always shows navigation data to the position shown on the Man Overboard screen whenever the Man Overboard key is pressed.
85 near the bottom of the screen. Contact the factory customer service department if the module fails the self test. Do not attempt to use this product if it fails the self test. To use the self test feature, press the MENU key, then press the key next to the "More" label.
86 PCF OFFSET The GPS navigation system relies on complex mathematical calculations to determine your position based on satellite data and other factors. One factor is the Earth's shape. Since the Earth is not a true sphere, variations in the calculations have to be made to accommodate deviations.
87 Press the key next to the "Ac- cept Offset" label when you've entered the desired latitude off- set. Repeat this procedure to change the longitude. In this example, we have entered 0 degrees,.012 minutes north lattitude and 0 degrees, .
