vi WARNING! A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION When showing navigation data to a position (waypoint), a GPS unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only tak[...]

1 Section 1: Read Me First! How this manual can get you out on the road, fast! Welcome to the exciting world of digital sonar and GPS! We know you're anxious to begin navigating and finding fish, but we have a favor to ask. Before you grab the unit and begin installing it, please give us a moment or two to explain how our manual can help you g[...]

Wh en yo u c om e t o a so na r m en u c om ma nd on th e L MS -480 s cr ee n, yo u c an look it up in the manual by skimming over the table of contents, just flip- ping through Sectio[...]

3 Now, if you're into the fine details, glance over the next segment on specifications to see just how much sonar and GPS power your unit con- tains. It's important to us (and our power users), but, if you don't care how many watts of power the unit has, or how many waypoints LMS-480 can store, skip a head t o impor tant i nform atio[...]

4 LM S-480D F. It has 35 ° /12 ° cone angles. A sin- gle-frequency Skimmer transducer with built- in temperature sensor is packed with the LM S-480. It ha s a 2 0 ° cone angle.

6 The transmitter emits an electrical impulse, which the transducer con- verts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object (fish, structure, bottom) and bounces back to the transducer, which converts the sound back into an electrical signal. The receiver a[...]

7 location in relation to those satellites. Once LMS-480 figures its lati- tude and longitude, it plots that position on the moving map shown on the screen. The whole process takes place several times a second! The performance doesn't stop there. Stored in the permanent memory of each LMS-480 is a basic background map of the entire world. We l[...]

8 The other key GPS use for MMCs is storage of special high-detail, cus- tom maps, which you can produce on your computer with our MapCre- ate software. These MapCreate custom maps contain much greater de- tail than the basic background map. These Custom Map Files (file format *.lcm) can also be shared between LMS-480s, other Lowrance GPS or sonar/[...]

9 A minimum of three satellites are required to determine a 2D fix. The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level — also called altitude.) This is called a 3D fix. Remember, the uni[...]

13 Section 2: Installation & Accessories Preparations You can install the sonar and GPS systems in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drill- ing any holes in your vehicle or vessel! 1. Determine the approximate location for the sonar/[...]

14 Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Re- member, the transducer installation is the most critical part of a sonar installation. NOTE: The following installation types also call for these recommended tools and required supplies that you must provide[...]

15 at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine. 3. The transducer should be installed with its face pointing straight down, if possible. For shoot-thru applications: Many popular fishing boat hulls have a flat keel pad that offers a good mounting surface. On vee hulls,[...]

16 usually give you the best combination of smooth water flow and protec- tion from bangs and bumps. Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If y[...]

17 Second, the transducer angle cannot be adjusted for the best fish arches on your sonar display. (This is not an issue for flasher-style sonars.) Lack of angle adjustment can be particularly troublesome on hulls that sit with the bow high when at rest or at slow trolling speeds. Third, a transducer CAN NOT shoot through wood and metal hulls. Thos[...]

18 Place the ratchets into the bracket with the letter "A" aligned with the alignment mark mold ed into the br acket . Place the ra tchet s onto t he transducer with the letter "A" aligned with the 12 o'clo ck position on the transducer stem. These positions set the transducer's coarse angle adjustment for a 14 ° tran[...]

19 If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you ca[...]

20 Assemble transducer and bracket. 3. Assembling the transducer. A. One-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the following fig- ure. Don't tighten the lock nut at this time. Assemble transducer and bracket. B. Two-piece bracket: Once you determine the correct position for[...]

21 Position transducer mount on transom and mark mounting holes. Side view shown at 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 Sk[...]

22 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[...]

23 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.) Attach motor mounting bracket to transducer. 2. Slide the adjustable strap supplied wit[...]

24 Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the trans- ducer 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[...]

25 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. Epoxy the transducer to a solid portion of the hull. For example, some (but n[...]

26 To choose the proper location for shoot-thru-hull mounting, follow these testing procedures: (You may need a helper to complete these steps.) 1. Anchor the boat in about 30 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat in the wate[...]

27 4. Most people can get good results by following steps 1 through 3, so this step is optional . If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe the bottom signal. You'll need to figure some way to prop the transducer into [...]

28 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the package and place them on the paper plate. Thoroughly stir the two compounds together until the mixture has a uniform color and consistency. Do not mix too fast or bubbles will form in the epoxy. After mixing, you have 20 minutes to complete the installat[...]

29 Once you've determined the proper location for the unit, place the sen- sor on the transom. The bottom of the bracket should be flush with the hull's bottom. Using the sensor as a template, mark the hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of the slots. Mount the sensor to the hull using #8 sta[...]

30 sor's socket. If you have any questions concerning the installation of the sensor, please contact your local boat dealer. GPS Antenna/Receiver Module The LMS-480 series package includes the LGC-2000 GPS module. This device contains the unit's external antenna and receiver for GPS and WAAS signals. The antenna/receiver module comes with[...]

31 In an automobile, you may achieve good results by simply placing the external antenna on the top of the dash, at the base of the windshield. A piece of the rubber non-skid shelf liner material available in recreational vehicle supply stores will help hold the antenna in place. This may not work well if you have a cab-over design pickup truck cam[...]

32 2000 Power cable's red wire should be attached (with provided 3-amp fuse) to the boat battery's positive terminal, and the NMEA-2000 Power cable's black and shield wires should both be attached to the battery's negative terminal. NOTE: If the NMEA-2000 buss draws power directly from the boat's battery, the LGC-2000 will [...]

33 For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse. Power connections for the LMS-480 series sonar/GPS unit. NOTE: If you're powering a NMEA-[...]

34 An optional 8-foot, CA-4 external power cable with a cigarette lighter adapter is available from Lowrance.

36 Mounting the Unit: Bracket, In-Dash or Portable You can install the LMS-480 on the top of a dash with the supplied gimbal bracket. It can also be installed in the dash or mounted on a portable power supply. If you use the supplied bracket, you may be interested in the optional R-A-M  bracket mounting system. This converts the unit's gimb[...]

37 Install the gimbal bracket. Orient the bracket so the arms slope toward the front of your unit. Drill a 1-inch (25.4 mm) hole in the dash for the power, transducer and antenna cables. The best location for this hole is immediately under the gimbal bracket location. This way, the bracket can be installed so that it covers the hole, holds the cabl[...]

38 After drilling the hole, pass the transducer connector up through the hole from under the dash, followed by antenna connector. Pass the power cable's bare-wire end down though the hole from the top. If you wish, you can fill in the hole around the cables with a good ma- rine caulking compound. (Some marine dealers stock cable hole covers to[...]

39 Portable Installation Like many Lowrance products, the LMS-480 is capable of portable op- eration by using the optional PPP-11 portable power pack. The power pack, the magnet-equipped antenna module and an optional portable transducer expand the uses for your sonar/GPS unit. The PPP-11 makes it easy to transfer your unit from a boat to a car, re[...]
