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 ahead to important information on how LMS-480 sonar works, on page 5.
Page 12 LMS-480DF. It has 35°/12° cone angles. A sin- gle-frequency Skimmer transducer with built- in temperature sensor is packed with the LMS-480. It has a 20° cone angle. Transducers operate at speeds up to 70 mph (61 kts). LMS-480: 1,000 feet/305 meters.

Zoom range:... 39 ranges; 0.02 to 4,000 miles. NOTE: The above memory capacities refer only to LMS-480's on-board memory. The amount of GPS or sonar data you can record and save for recall later is only limited by the number of MMC cards you have.
Page 14: How Lms-480 Gps Works
First, think of your LMS-480 as a small but powerful computer. (But don't worry — we made the LMS-480 series easy to use, so you don't need to be a computer expert to find your way!) The unit includes a keypad and a screen with menus so you can tell LMS-480 what to do.
Page 15 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 lock it in here at the factory — you can't change or erase this map.
Page 16: Introduction To Gps And Waas
Introduction to GPS and WAAS Well, now you know the basics of how LMS-480 does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page 13, so you can mount your unit and plug in the power. Or you might want to see how our text formatting makes the manual tutorials easy to skim.
Page 17 These signals can be easily blocked by trees, buildings, an automobile roof, even your body. Like most GPS receivers, LMS-480 doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the sat- ellites to calculate a position.
Page 18: How To Use This Manual: Typographical Conventions
Alaska, that do not yet receive robust WAAS coverage. Continued WAAS development is planned to extend WAAS coverage in the years to come. WAAS boosts the accuracy of land GPS navigation, but the system is designed for aircraft. The satellites are in a fixed orbit around the Equator, so they appear very low in the sky to someone on the ground in North America.
Page 19 Instructions = Menu Sequences Most functions you perform with LMS-480 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.

Page 21: Sec. 2: Installation & Accessories
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.
Page 22: Selecting A Transducer Location
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 (supplies listed here are not included): Single-frequency transom installations...
Page 23: How Low Should You Go
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.
Page 24: Shoot-Thru-Hull Vs. Transom Mounting
usually give you the best combination of smooth water flow and protec- tion from bangs and bumps. Transducer centerline 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 you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be coming out of the water as you cross waves or wakes.
Page 25: Transom Transducer Assembly And Mounting
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.
Page 26 Place the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket. Place the ratchets onto the transducer with the letter "A" aligned with the 12 o'clock position on the transducer stem. These positions set the transducer's coarse angle adjustment for a 14°...
Page 27 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.

Page 30 Flat-bottom 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.
Page 31: Trolling Motor Bracket Installation
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.) Bolt Attach motor mounting bracket to transducer. 2.

Transducer aimed too far back Full fish arch 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.
Page 33 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. Fill with polyester resin Flotation material Epoxy to hull first...
Page 34 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 water.
Page 35 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.
Page 36: Speed/Temperature Sensors
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.
Page 37 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 stainless steel wood screws (not included).

Y-adapter extension cable as shown in the following dia- gram. To connect it to the LMS-480, insert the cable's splitter plug into the Network socket on the back of the unit and your system is ready to use.
Page 39: Power Connections
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 camper or motor home.
Page 40: Powering Your Unit
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 remain on (drawing power) all the time.

Page 69: Calibrate Speed
A good way to gauge your speed sensor's performance is to compare its reading with the ground speed measured by your unit's GPS functions. When you make a run to compare GPS ground speed to speed sensor speed, perform your test in relatively calm water free of current, if pos- sible.
Page 70: Chart Speed
Chart Speed The rate that echoes scroll across the screen is called the chart speed. The default is maximum; we recommend that you leave the speed set there for virtually all fishing conditions. However, you might consider experimenting with chart speed when you are stationary or drifting very slowly.

Page 104 3. The water may be deeper than the sonar's ability to find the bottom. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously. It may change the range to limits far greater than the water you are in. If this hap- pens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity.
Page 105 To eliminate or minimize the effects of electrical noise, first try to de- termine the cause. With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make sure the engine is also off.

Page 111 You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north. The GPS receiver is tracking satellites that are in bold type. The re- ceiver hasn't locked onto a satellite if the number is grayed out, there- fore it isn't being used to solve the position.
Page 112: Navigation Page
This also gives you an indicator of the fix quality the unit currently has. The smaller the position error number, the better (and more ac- curate) the fix is. If the position error flashes dashes, then the unit hasn't locked onto the satellites, and the number shown isn't valid. (For details, see the Customize Page Displays entry in Sec.
Page 113 When navigating to a waypoint, the Navigation screen looks like the following figure. Your ground speed, track, distance and bearing to waypoint, and course are all shown digitally on this screen. NOTE: Remember, when the Speed, Track and Position information dis- plays are flashing, satellite lock has not been achieved and no posi- tion fix has been determined.
Page 114: Map Page
The cross track error range is shown on the compass rose as a wide, white, corridor enclosing the course line. The outer edges of this white corridor represent lines that show the current cross track error range. The default for the cross track error range is 0.20 miles. For example, if the present position symbol touches the right cross track error line, then you are 0.20 miles to the right of the desired course.
Page 115 The arrow in the center of the screen is your present position. It points in the direction you're traveling. The solid line extending from the back of the arrow is your plot trail, or path you've taken. The map zoom range is the distance across the screen. This number shows in the lower right corner of the screen.
Page 116: Background Map Vs. Mapcreate Map Content
What's more important is the large scale map detail that allows your GPS unit to show a higher level of position accuracy. For example, the background map would show you the general outline and approximate shape of a coastline or water body, but the higher detail in MapCreate shows the shoreline completely and accurately (finer detail).
