Copyright © 1996, 1997, 1998 Lowrance Electronics, Inc. All rights reserved. AirMap™ 100 is a trademark of Lowrance Avionics. Lowrance® is a registered trademark of Lowrance Electronics, Inc. Jeppesen® is a registered trademark of Jeppesen Sanderson, Inc. WARNING! USE THIS UNIT ONLY AS AN AID TO NAVIGATION. A CAREFUL NAVI- GATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSI- TION INFORMATION. Never use this product while operating a vehicle. The background map built into this unit is not intended for navigation and its accuracy has not been verified. This map is derived from U.S. govern- ment sources which rely on ground and aerial surveys and satellite data. Since there can be inaccuracies in the data used to create the maps and in the map’s resolution, plus position inaccuracies in the navigation sys- tem, use caution when using this product. CAUTION When showing navigation data to a position (waypoint), this unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent naviga- tor will not only take advantage of all available navigation tools when trav- elling to a waypoint, but will also visually check to make certain a clear, safe path to the waypoint is always available. The operating and storage temperature for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 to +75 degrees Celsius). Extended storage temperatures higher or lower than specified will cause the liquid crystal display to fail. Neither this type of failure nor its consequences are cov- ered by the warranty. For more information, consult the factory customer service department. All features and specifications subject to change without notice. Lowrance Avionics may find it necessary to change or end our policies, regulations, and special offers at any time. We reserve the right to do so without notice. All screens in this manual are simulated.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interfer- ence in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accor- dance with the instructions, may cause harmful interference to radio com- munications. However, there is no guarantee that interference will not oc- cur in a particular installation. If this equipment does cause harmful inter- ference to radio or television reception, which can be determined by turn- ing the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the factory customer service department for help.

INTRODUCTION Thank you for purchasing a Lowrance Avionics AirMap 100. With its large LCD screen, easy to use menus, and outstanding performance, we think you’ll be happy with your AirMap 100 for many years. No other handheld GPS receiver on the market today has the AirMap’s combination of 12 channel receiver, Jeppesen® database with obstacles (U.S. only), ground and hydrographic mapping capability, and programmable screens in a handheld unit. The Global Positioning System (GPS) was developed by the United States Department of Defense as a 24-hour a day, 365 days a year global navi- gation system for the military. Civilian availability was added (but with less accuracy) using the same satellites. Twenty-four satellites orbit the Earth. Three of these satellites are spares, unused until needed. The rest virtu- ally guarantee that at least four satellites are in view of anyplace on Earth at all times. The system requires 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.) called a 3D fix. Remember, the unit must have a clear view of the satellites in order to receiver their signals. Unlike radio or television, GPS works at very high frequencies. The signals can be blocked easily by trees, buildings, even your body. Fortunately, they do travel through glass and plastic, so your receiver will work in the aircraft, if it has a clear view of the satellites through the windshield or side windows. Let someone else drive if you use it in a car or other vehicle. Never use this GPS receiver while operating a vehicle! The first time you use this unit, walk outside and turn it on in your back- yard, an open field or park. Once it locks onto the satellites, you can ex- periment with it around buildings and trees. This will give you some idea of its sensitivity to blockage. Like most GPS receivers, this unit doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the satellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for it to determine direction of travel, you must be moving and the faster, the better. This is not to say that it won’t work at walking speeds - it will. There will simply be more “wandering” of the data shown on the display. 1

SA - What is it? Another factor that greatly influences the receiver’s ability to determine position is SA. The United States government intentionally degrades the satellites signal for civilian users. They introduce small errors into the satellite’s signals that makes the GPS receiver less accurate. These er- rors are called selective availability, or SA. How bad is it? They guarantee that the position reported by a GPS receiver that meets their specifica- tions is within 100 meters horizontally and 150 meters vertically 95% of the time. (The position can be better than that or worse than that the other 5% of the time.) In other words, the position shown on your receiver is within 100 meters of your actual position, 95% of the time. That’s over 300 feet! Not exactly pinpoint accuracy, but then few people need positioning accuracy greater than this. However, if you do want better performance, (and who doesn’t?) many manufacturers (including Lowrance) sell a DGPS receiver that attaches to your GPS receiver. The DGPS system transmits correction signals that nullify the effects of SA. The DGPS receiver takes signals from these land-based transmitters and gives them to the GPS receiver which then uses them to show a more accurate position. The ironic part is the federal government implemented SA and is also operat- ing many DGPS transmitters. (You can use the signals from all of the Coast Guard DGPS stations for free, by the way.) The downside to this is it requires another piece of electronic gear (the DGPS receiver) which usually isn’t small enough to carry with you, but will work nicely on a vehicle. And you have to be close enough to a station to receive the DGPS signals. Don’t Get Lost Generally, you find that using your GPS receiver without DGPS is both easy and amazingly accurate. It’s easily the most accurate method of electronic navigation available to the general public today. Remember, however that this receiver is only a tool. Always have another method of navigation available, such as a chart or map and a compass. It’s a good idea to carry spare batteries with you, especially if you’re venturing into unknown territory. Also remember that this unit will always show navigation information in the shortest line from your present position to a waypoint, regardless of terrain! It only calculates position, it can’t know what’s between you and your camp, for example. It’s up to you to safely navigate around obstacles, no matter how you’re using this product. 2
