The GPS II+ represents GARMIN's continuing commitment to provide quality navigation information in a versatile and userfriendly flexible design you'll enjoy for years. To get the most from your new GPS, take the time to read through the owner's manual in order to understand the operating features of the GPS II+. This manual is organized into three sections for your convenience: Section One takes you through step-by-step instructions to initialize the receiver for first-time use. Section Two (Getting Started Tour) introduces you to the basic features of the unit and provides a quick-start orientation to the GPS II+. Section Three (Reference) provides details about the advanced features and operations of the GPS II+ by topic. Before getting started with your GPS, check to see that your GARMIN GPS II+ package includes the following items. If you are missing any parts, please contact your dealer immediately. Standard Package: · GPS II+ Unit · Wrist Strap · GPS II+ Owner's Manual · Velcro Mount i Cautions The Global Positioning System (GPS) is operated by the government of the United States, which is solely responsible for its accuracy and maintenance. The system is subject to changes which could affect the accuracy and performance of all GPS equipment. Although the GPS II+ is a precision electronic NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted and, therefore, become unsafe. For vehicular applications, it's the sole responsibility of the owner/operator of the GPS II+ to secure the GPS unit so that it will not cause damage or personal injury in the event of an accident. Do not mount the GPS II+ over airbag panels or in a place where the driver or passengers are likely to have an impact with it in an accident or collision. The mounting hardware provided by GARMIN is not warranted against collision damage or the consequences thereof. For vehicular operations, it is the sole responsibility of the operator of the vehicle to operate his or her vehicle in a safe manner, maintain full surveillance of all driving conditions at all times, and never become distracted by the GPS II+ to the exclusion of safe operating practices. It is unsafe to operate the GPS II+ while you are driving. Failure by the operator of a vehicle equipped with a GPS II+ to pay full attention to operating the vehicle and road conditions while the vehicle is in motion could result in an accident or collision with property damage and personal injury. ! ! ! ii FCC Compliance This device complies with Part 15 of the FCC limits for Class B digital devices. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. There is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to other equipment, which can be determined by turning the affected equipment off and on, the user is encouraged to try and correct the interference by relocating the equipment or connecting the equipment to a different circuit than the affected equipment. Consult an authorized dealer or other qualified service technician for additional help if these remedies do not correct the problem.

What is GPS? GPS is a system of 24 satellites which circle the earth twice a day in a very precise orbit and transmit information to earth. The GPS II+ must continuously "see" at least three of these satellites to calculate your position and track your movement. By using an almanac (a timetable of satellite numbers and their orbits) stored in the receiver's memory, the GPS II+ can determine the distance and position of any GPS satellite and use this information to compute your position. Your GPS receiver can only see satellites above the horizon, so it needs to know what satellites to look for at any given time. To use this almanac data, your GPS needs to either be told its general location or given the opportunity to find itself, or "initialize." Once you initialize the unit to a position, it will usually compute a fix within a few minutes. We'll show you how to initialize your new GPS on p. 7. Initialization is only necessary under the following conditions: · The first time you use your receiver (from the factory). · After the receiver has been moved over 500 miles from the last time you used it (with the power off). · If the receiver's memory has been cleared and all stored data has been lost. 1 Satellite Acquisition Satellite Acquisition Because the GPS II+ relies on satellite signals to provide you with navigation guidance, the receiver needs to have an unobstructed, clear view of the sky for best performance. In a nutshell, the GPS receiver's view of the sky will generally determine how fast you get a position fix--or if you get a fix at all. GPS signals are relatively weak and do not travel through rocks, buildings, people, metal, or heavy tree cover, so remember to keep a clear view of the sky at all times for best performance. Once the GPS II+ has calculated a position fix, you'll usually have anywhere from four to twelve satellites in view. The receiver will then continuously select the best satellites in view to update your position. If some of the satellites in view get blocked or "shaded," the receiver can simply use an alternate satellite to maintain the position fix. Although a GPS receiver needs four satellites to provide a three-dimensional (3D) fix, it can maintain a two-dimensional (2D) fix with only three satellites. A threedimensional fix means the unit knows its latitude, longitude, and altitude, while a two-dimensional fix means the unit knows only its latitude and longitude. To prevent accidental battery power loss, the GPS II+ will automatically shut off 10 minutes after the last keystroke if the unit is not tracking at least one satellite and has not acquired a position fix. 2 Battery Installation Battery Installation The GPS II+ operates on 4 AA batteries (not included), which are installed at the base of the unit. These batteries provide up to 24 hours of use. To install the batteries: 1. Flip up the metal ring at the base of the unit, and turn the ring 90° counter clockwise. 2. Install the batteries (Fig. 3), and close the battery compartment door. 3. Lock the door in the closed position by rotating the metal ring 90° clockwise. Polarity Markings Battery life varies due to a variety of factors, including temperature and backlighting. You may find that the battery life varies in different conditions and that lithium batteries provide longer life in colder conditions. When replacing the GPS II+'s batteries, observe the polarity markings engraved in the plastic case. An internal 10-year lithium battery will retain your data while you're changing batteries.
