GPS III A 7/21/98 8:51 AM Page 3 GETTING STARTED The GPS III operates on 4 AA batteries (not included), which are installed at the base of the unit. These batteries provide up to 8 hours of continuous use. Rechargeable NiCad or lithium batteries may also be used. # ? Battery Installation Polarity Markings NOTE: The on-screen battery level indicator is calibrated for alkaline batteries, and will not be accurate when using NiCad or lithium batteries (see page 69). To install the batteries: 1.
GPS III A 7/21/98 8:51 AM Page 4 GETTING STARTED What is GPS? Hold the receiver at a comfortable height with the antenna pointing up. When new (or if a position cannot be determined after 10 minutes), the GPS III will prompt you to initialize the receiver. The unit needs a starting position to determine 4 which satellites are in view. The Global Positioning System (GPS) is a system of 24 satellites which circle the earth twice a day in a very precise orbit and transmit information to earth.
GPS III A 7/21/98 8:51 AM Page 5 GETTING STARTED Once the GPS III has calculated a position fix, you’ll usually have anywhere from five 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.
GPS III A 7/21/98 8:51 AM Page 6 GETTING STARTED Initialization This usually provides a position fix in 1 minute. You’ll know you have a fix when the unit automatically transitions from the Satellite Page to the Map Page (shown left). Your receiver is now ready to use! To turn the unit off: 1. Press and hold the red power key for 1 second. To initialize the GPS III, designate your approximate location directly on the map display.
GPS III A 7/21/98 8:51 AM Page 7 GETTING STARTED Main Page Sequence Satellite Status Page Position Page Press the PAGE key to move through each of the main pages in normal fashion. Active Route Page Highway Page Map Page Compass Page To turn the GPS III back on, press and hold the red power key. The GPS III features six main pages which are linked together in a chain. You can quickly scroll through the pages in either direction using the PAGE or QUIT keys.
GPS III A 7/21/98 8:51 AM Page 8 GETTING STARTED Satellite Status Page The signal strength bars give you an indication of what satellites are visible to the receiver, whether or not they’re being used to calculate a position fix, and the signal quality. 8 If satellite reception is lost, or an insufficient number of satellites are available, you will be alerted with a ‘Poor Coverage’ receiver status and message.
GPS III A 7/21/98 8:51 AM Page 9 GETTING STARTED The Position Page shows you where you are, what direction you’re heading, and how fast you’re going—and it’s the page you’ll want to use when you don’t have a destination selected. A graphic compass display at the top of the page shows your direction of travel (track) while you’re moving, while six user-selectable data fields below display your current speed, average speed, trip odometer, trip timer, and sunrise/sunset times at your current position.
GPS III A 7/21/98 8:51 AM Page 10 GETTING STARTED Map Page The Map Page shows your movement using a real-time track log (an electronic breadcrumb trail that appears directly on the map as you’re traveling), and your present position as a pointer icon in the center of the map. The Map Page also shows any nearby lakes, rivers, highways and towns. Use the zoom keys (IN and OUT) to adjust the map to the desired scale. To change the map scale: 1.
GPS III A 7/21/98 8:51 AM Page 11 GETTING STARTED The GPS III features two different navigation pages: Compass and Highway. The Compass Page is first. This page provides graphic steering guidance to a destination waypoint, with an emphasis on the bearing to your destination and current direction of travel. (The Highway Page places greater emphasis on the straight-line desired course and the distance and direction you are off course.
GPS III A 7/21/98 8:51 AM Page 12 GETTING STARTED Highway Page If you move off course the highway display will move, indicating the direction you are off course. To stay on course, simply move toward the center of the highway. 12 As you approach your destination, the graphic highway will stop at the destination waypoint. You have arrived when the waypoint is at the bottom center of the display. The GPS III’s Highway Page also provides graphic steering guidance to a destination waypoint.
GPS III A 7/21/98 8:51 AM Page 13 GETTING STARTED The GPS III’s Main Menu provides access to additional pages (submenus) that are used to create or edit waypoints, create routes, list nearby waypoints, review trip information and timers or make changes to system settings. These six pages are divided into categories by function. The waypoint and route management features of the Main Menu are described in more detail in the Reference section of this manual.
GPS III A 7/21/98 8:51 AM Page 14 GETTING STARTED Marking Waypoint Positions GPS is really about marking and going to places called ‘waypoints’. Before we can use the GPS III to guide us somewhere, we have to mark a position as a waypoint. Your GPS III can hold up to 500 waypoints. To mark your present position: 1. Press and hold the ENTER/MARK key. The Mark Waypoint Page will appear, with a default three-digit name for the new waypoint in the upper-left portion of the page.
GPS III A 7/21/98 8:51 AM Page 15 GETTING STARTED Once you’ve stored a waypoint in memory, you can use the GPS III to guide you to it by using the GOTO feature. A GOTO is really nothing more than a straight-line course from your present position to the destination you’ve selected. A GOTO can be performed several ways: by specifying the destination from the GOTO Page, graphically from the map display or by highlighting the waypoint name on any page (such as the Nearest Waypoints List).
GPS III A 7/21/98 8:51 AM Page 16 GETTING STARTED Cancel GOTO/Active Route To cancel the current GOTO destination, simply select another destination. If no destination is currently desired, or you want to resume a previously selected route, the GOTO operation may be cancelled from the GOTO Options Page. To cancel the current GOTO destination: 1. Press GOTO. 2. Press MENU. 3. Highlight ‘Cancel GOTO’ and press ENTER. To cancel the current GOTO destination, select ‘Cancel GOTO’ from the GOTO Options Page.
GPS III A 7/21/98 8:51 AM Page 17 SIMULATOR TOUR The GPS III is a powerful navigation system providing detailed mapping information in a convenient, compact package.

If you pass the waypoint the pointer will 24 swing around, pointing down. To view the Highway Page, press PAGE.
GPS III A 7/21/98 8:51 AM Page 25 REFERENCE The GPS III’s Satellite Status Page provides a visual reference of various receiver functions, including current satellite coverage, receiver operating mode, battery level and position accuracy. As the receiver locks onto satellites, a signal strength bar will appear for each satellite in view, with the appropriate satellite number (01-32) underneath each bar.
GPS III A 7/21/98 8:51 AM Page 26 REFERENCE Satellite Status Page ‘2D Navigation’ means the GPS III has determined a horizontal position (latitude/ longitude), but is unable to determine altitude. Additional satellites may be needed. 26 ‘3D Navigation’ means the GPS III has determined a horizontal and vertical position (latitude, longitude and altitude). The receiver is ready for navigation.
GPS III A 7/21/98 8:51 AM Page 27 REFERENCE Poor GPS Coverage— the receiver isn’t tracking enough satellites for a 2D or 3D fix due to bad satellite geometry. Not Usable— the receiver is unusable, possibly due to incorrect initialization or abnormal satellite conditions. Turn the unit off and back on to reset, and reinitialize the receiver if necessary. Simulating Nav— the receiver is in simulator mode.
GPS III A 7/21/98 8:51 AM Page 28 REFERENCE Satellite Status Page When screen backlighting is on, a bulb icon will appear in the lower-left corner of the Satellite Status Page. EPE and DOP The Satellite Status Page also indicates the accuracy of the position fix, using Estimated Position Error (EPE) and Dilution of Precision (DOP) figures. DOP measures satellite geometry quality (i.e., number of satellites received and where they are relative to each other) on a scale from one to ten.
GPS III A 7/21/98 8:51 AM Page 29 REFERENCE The following Satellite Status Page options are available: Satellite Status Page Options Start Simulator— allows you to activate the GPS III’s built-in simulator mode.
