Transom Transom

Position transducer mount on transom and mark mounting holes. Side view shown, left, and seen from above at right.
5. Attaching transducer to transom. A. One-piece bracket: Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures.
For single-frequency Skimmer, route cable over bolt and through bracket. Side view shown, left, and seen from above at right.
Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the sealant. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn. Don't over tighten the lock nut! If you do, the transducer won't "kick-up" if it strikes an object in the water.

Bottom of hull

Flat-bottom hull Deep-"vee" hull Align transducer centerline with hull bottom and attach transducer to transom. Rear view of dual-frequency Skimmer shown.
6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires. WARNING: Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed. If you need to drill a hole in the transom to pass the connector through, the required hole size be 1". Caution: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the mounting screws. 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull!
Trolling Motor Bracket Installation (single-frequency only) 1. Attach the optional TMB-S bracket to the transducer as shown in the following figure, using the hardware supplied with the transducer. (Note: The internal tooth washer is supplied with the TMB-S.)

Internal tooth washer Bolt Nut TMB-S bracket
Flat washer Attach motor mounting bracket to transducer.
2. Slide the adjustable strap supplied with the TMB-S through the slot in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the water. Tighten the strap securely. 3. Route the transducer cable alongside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the trolling motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use.

Transducer Orientation and Fish Arches If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds. 17

Partial fish arches

Transducer aimed too far forward
Full fish arch Proper transducer angle Transducer angles and their effects on fish arches.
If the arch slopes up but not back down then the front of the transducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation. Shoot-Thru-Hull Preparation
Hulls With Floatation Materials
The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area. See the following figure. 18
WARNING: Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications.

Face Cover

Your unit comes with a white protective cover that snaps on and off the front of the unit. This cover is intended for use when your unit and the vehicle it's mounted in are idle. 33
WARNING: When the unit is mounted in an unprotected area, such as an open boat cockpit, the protective face cover must be removed when the vehicle is moving at high speed. This includes towing a boat on a trailer at highway speeds. Otherwise, wind blast can pop off the cover.
Section 3: Basic Sonar Operation
This section addresses the unit's most basic sonar operations. The instructions presented here in Sec. 3 follow a chronological order. Sec. 4, Sonar Options & Other Features, will discuss options and other more advanced functions and utilities. The material in Sec. 4 is arranged in alphabetical order. Before you turn on the unit, it's a good idea to learn about the different keys, the Main Menu, the Sonar Menu, the five Page options and how they all work together. BUT, if you just can't wait to get on the water, turn to the one-page Quick Reference on page 43.

Keyboard

1. PWR/LIGHT (Power & Light) The PWR key turns the unit on and off and activates the backlight. 2. PAGES Pressing this and the arrow keys switches the unit between the five different page options. (Full Sonar Chart, Split Zoom Sonar Chart, Split Frequency Sonar Chart, Digital Data and FlashGraf.) 3. MENU Press this key to show the menus and submenus, which allow you to select a command or adjust a feature. 35
4. ARROW KEYS These keys are used to navigate through the menus, make menu selections, move the sonar chart cursor and enter data. 5. ENT (Enter) This key allows you to accept values or execute menu commands. 6. EXIT The Exit key lets you return to the previous screen, clear data or erase a menu. 7. ALARM The Alarm key is a quick shortcut to the sonar alarms menu. It allows you to choose which alarms to use and when. 8. ZOUT (Zoom Out) This key lets you zoom the screen out. This key returns you to a full sonar chart display, showing the entire water column from surface to bottom. 9. ZIN (Zoom In) This key lets you zoom the screen in. It enlarges fish signals, bottom detail and other sonar returns.

Power/lights on and off

To turn on the unit, press PWR. To change the backlight, press PWR again. The X-510c and X-515cDF have three backlight levels. Repeatedly pressing PWR will cycle through the backlight settings, turn off the backlight, then turn it back on again. Turn off the unit by pressing and holding the PWR key for about 3 seconds.
Your sonar unit will work fine right out of the box with the factory default settings. You only need to learn a few basic functions to enhance your viewing. We'll discuss them briefly here, then talk about them and all the other commands in more detail in the next section, which begins on page 49. Your unit has three primary menus that control its operation. They are the Main Menu, the Sonar Menu and the Pages Menu. Main Menu The Main Menu contains some basic function commands and some setup option commands. You access the Main Menu by pressing MENU|MENU. You run a command by using the or to highlight the command and then pressing ENT. To clear the Main Menu screen and return to the Page display, press EXIT. (Remember, our text style for "MENU|MENU" means "press the Menu key twice." See a full explanation of our instruction text formatting on page 4, Instructions = Menu Sequences.) 36
Main Menu. Main Menu Commands
There are four "basic" Main Menu commands that you'll really want to read more about. They are: Screen: changes the contrast or brightness of the display screen. Use this command to adjust how the screen looks under various lighting conditions. Sounds: enables or disables the sounds for key strokes and alarms, controls the volume and sets the alarm style. If you don't like to hear a beep each time you press a key, you can turn this off, or select tunes or sound effects instead. The sounds are especially useful when used with the Fish I.D. fish symbol feature and fish alarm feature. Sonar Alarms: turns alarms on or off and changes alarm thresholds. The fish alarm, used with Fish I.D., is the most popular use. It tells you when the sonar sees a fish. You can also set deep or shallow depth alarms and zone alarms. Popup Help: turns the pop-up help boxes on or off. When you select a menu command, these information boxes appear to tell you what the command does or how to use the command. The default setting is on, which is really handy while you're learning. The remaining Main Menu commands are for more advanced functions, mostly setting various sonar options. (They're all detailed in Sec. 4.) Transparency: adjust the level of transparency for menus. Units of Measure: selects the units of measure used for showing speed/distance, depth and temperature. Set Keel Offset: calibrates the unit to show depth under the keel or actual depth from the surface. 37

The Pages Menu has two tabs, one for sonar, the other for radar. The Sonar tab has six major display options: Full Sonar Chart, Split Zoom Sonar Chart, Split Frequency Sonar Chart (X-515cdf only), Digital Data, Flasher and Sonar with Custom Gauges. Select the Radar tab to display the radar page. You can access the Pages Menu by pressing the PAGES key. You select a display option by using or to highlight the option and then pressing ENT. (You can clear the Pages Menu by pressing EXIT.)
Sonar Page Display options (left). Radar Page (right). Remember: the Split Frequency Sonar Chart will not be listed on the X-510c menu since it does not have a dual frequency transducer.
The Full Sonar Chart is the main display option. This is a "crosssection" view of the water column beneath the boat. The chart moves across the screen, displaying sonar signal echoes that represent fish, structure and the bottom.

Section 4, but to show you how easy the sonar unit is to operate, the following page contains a simplified, 10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory.
Basic Sonar Quick Reference
1. Depress the PWR key to turn on the unit. 2. Head for your fishing grounds. Your unit automatically displays digital depth and surface water temperature in the corner of the screen. The auto settings will track the bottom, displaying it in the lower portion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water. 3. As you're watching the sonar returns, you can change the display by: Zoom in to enlarge the chart for more detail: press ZIN. Zoom out to return to full chart mode: press ZOUT. 4. If necessary, adjust sensitivity to improve chart readability. Press MENU|ENT and the Sensitivity Menu will appear on the left of your screen. Use and to change the setting. Boosting sensitivity will show more information on your screen, which may cause clutter. Reducing sensitivity will filter out some information, but could omit important images. We recommend adjusting sensitivity until the background is lightly "peppered" that is, scattered dots appear, but individual objects (like fish arches or bottom structure) can be easily picked out of the background. 5. Watch the display for the appearance of fish arches. When you see arches, you've found fish! Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart. 6. Gauge the fish depth by visually comparing the fish arches with the depth scale on the right side of the screen, or get a more accurate measure with the Depth Cursor. Press MENU| to DEPTH CURSOR|ENT. Press (or ) to align the cursor line with the fish arch. The exact depth appears in a box at the right end of the cursor line. To clear the cursor, press EXIT. 7. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom. 8. To turn off the unit, press and hold PWR key for three seconds.

Fish Alarm Use the fish alarm for a distinctive audible alarm when fish or other suspended objects are detected by the Fish I.D. feature (Fish I.D. must be turned on for the Fish Alarm to work). a different tone sounds for each fish symbol size shown on the display.

Sonar Page menu with ColorLine command selected (left). The ColorLine control bar (right).

Colorline

lets you distinguish between strong and weak echoes. It "paints" a brighter color on targets that are stronger than a preset value. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddy or weedy bottom returns a weaker signal which is shown with a narrow, colored line (dark blue tinged with red or a little yellow.) Since fish are among the weakest echoes, they show up mostly as blue arches. A hard bottom or other relatively hard target returns a strong signal which causes a wider brightly colored line (reddish yellow to bright yellow.) If you have two signals of equal size, one with red to yellow color and the other without, then the target with brighter color (yellow) is the stronger signal. This helps distinguish weeds from trees on the bottom, or fish from structure. ColorLine is adjustable. Experiment with your unit to find the ColorLine setting that's best for you. To adjust the Colorline level 1. From the Sonar Page, press MENU| to COLORLINE|ENT. 2. The Colorline Control Bar appears. Press to decrease Colorline; press to increase Colorline. 3. When it's set at the desired level, press EXIT.

Frequency (Change Transducer Frequency) (X-515cDF only)
The "DF" in your unit's name refers to its dual-frequency transducer, which operates with both 200 kHz and 50 kHz. The 200 kHz frequency has a 12 cone angle and the 50 kHz frequency has a 35 cone angle. The default frequency is 200 kHz, which is best for use in shallow water (about 300 feet or less). This frequency is the best choice for about 80 percent of the fresh and saltwater sport fishing applications. When you get into very deep saltwater 300 to 500 feet or deeper the 50 kHz frequency is the best choice. The 200 kHz transducer will give you better detail and definition, but less depth penetration. The 50 kHz transducer will give you greater depth penetration, but a little less detail and less definition. (Remember, all sonar units typically read deeper in fresh water than in saltwater.) There is a common exception to these rules. Some fishermen, who use downriggers on freshwater lakes (or the ocean), like to see their bait on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle. 62

Full Sonar Chart This is the default mode used when the unit is turned on for the first time or when it's reset to the factory defaults. The bottom signal scrolls across the screen from right to left. Depth scales on the right side of the screen aid in determining the depth of targets. The line at the top of the screen represents the surface. The bottom depth and surface temperature (if equipped with a temperature sensor or a transducer with a temp sensor built in) show at the top left corner of the screen. The FasTrack display is just to the right of the depth scale. This changes all echoes into short horizontal bars, replicating a flasher sonar. The zoom bar on the far right shows the area that's magnified when the zoom is in use. (See the Zoom section on page 86 for more information.)

WARNING: Microwave Radiation Hazard The microwave energy radiated by a radar antenna is harmful to humans, especially to the eyes. NEVER look directly into an open waveguide or into the path of radiation from an enclosed antenna. Radar and other radio frequency radiation can upset cardiac pacemakers. If someone with a cardiac pacemaker suspects abnormal operation, immediately turn off the radar equipment and move the person away from the antenna. Turn off the radar whenever it is necessary to work on the antenna unit or other equipment in the beam of the radar. WARNING: Turn Off Radar When Docked The radar beam can be harmful to humans in close proximity (within 20 yards, or 18.3 meters). When docked, be considerate of other boats and pedestrians nearby and remember to turn off your radar. If your boat is in a covered marina and the radar is on, a metal roof can act as a reflector, bouncing microwave energy back at your boat and passengers.

Section 1: Introduction

Thank you for buying a Lowrance Radar with the RIM 200 radar interface module. Your radar consists of three main components: the radar scanner unit (antenna), your display unit (sold separately) and the RIM 200 radar interface module which connects the scanner and display units. WARNING: Radar radiation can be harmful to you and bystanders. Radar misuse or misunderstanding radar operation could lead to a collision, which could result in property damage, personal injury or death. You must be familiar with the procedures and all warnings and cautions described in the installation and operation manuals in order to operate your radar safely and effectively. We know youre eager to begin using your radar, but first, we want you to take note of the three instruction manuals you need to read to get started. First is the Read Me! Insert for Radar Display Unit Software Update (part number 988-0161-023). It tells you how use the memory card in your package to update your display unit software to make it radarready. (For your convenience, this information is also repeated below.) Second is the Radar and RIM 200 Installation Manual (part number 988-0161-041). It tells you how to install your radar's hardware. Third is this Radar Operation Manual (part number 988-0161-012). After installing the radar scanner unit, the RIM 200 and the new display software, you need to read this manual to learn how your display unit and radar antenna work together. To get the highest level of performance from your radar, it is a good idea to keep this manual and your display unit's sonar or GPS instruction manual handy for reference.

What is radar?

The word "radar" is an acronym for "RAdio Detecting And Ranging." In simple terms, this is how it works: A radio transmitter sends out a quick microwave pulse. A receiver listens for that signal's echo when it bounces back from something in its path. When the echo returns, it is processed by a computer to determine relative distance, position and bearing of the object that reflected the signal. This information is displayed on the display unit's screen. Other boats or ships, navigational markers, landmasses and the like are referred to as targets. By knowing how long it takes for a signal to return, the distance to a target can be determined. As the radar antenna scans through a 360 degree rotation, it can show where the target is relative to your position. By repeated scans, you can see which direction another vessel is moving. The following two pages show the basic components of your radar display screen, which is commonly referred to as the PPI, an old term from the early days of radar.
How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type, so you can easily skim the instructions and pick out what menu command to use. Arrow Keys The arrow keys control the movement of dotted cross-hair lines on your mapping screen called the cursor. The arrow keys also control a horizontal line depth cursor on the sonar screen. The arrow keys also help you move around the menus so you can execute different commands. They are represented by symbols like these, which denote the down arrow, up arrow, left arrow and right arrow: . Keyboard The other keys perform a variety of functions. When the text refers to a key to press, the key is shown in bold. For example, the "Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU. Menu Commands A menu command or a menu option will appear in small capital letters, in a bold sans serif type like this: ROUTE PLANNING. These indicate that you are 3

to select this command or option from a menu or take an action of some kind with the menu item. Text that you may need to enter or file names you need to select are show in italic type, such as trail name. Instructions = Menu Sequences Most functions you perform with this unit are described as a sequence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading. For example, instructions for accessing the My Trails menu would look like this: 1. From the Map Page, press MENU|MENU| to MY TRAILS|ENT. In clearer terms, step 1 (above) means: "From the Map Page, press the Menu key twice. Use the arrow keys to select (highlight) My Trails menu and press Enter."
