GETTING ST ARTED Batter y Installation 3 The GPS III+ operates on 4 AA batteries (not included), which are installed at the base of the unit. These batteries provide up to 36 hours of continuous use (See page 87). Rechargeable NiCad or lithium batteries may also be used. NOTE : The on-screen batter y level indicator is calibrated for alkaline batte[...]

What is GPS? GETTING ST ARTED The Global Positioning System (GPS) is a system of 24 satellites which circle the earth twice a day in a ver y precise orbit and transmit information to earth. The GPS III+ must continuously “see” at least three of these satellites to calculate your position and track your movement. At times, additional satellites [...]

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 pos[...]

This usually provides a position fix in 1 minute. Y ou’ll know you have a fix when the unit automatically transitions from the Satellite Page to the Map Page, unless you have manually changed pages (shown left). Y our receiver is now ready to use! T o turn the unit off: 1. Press and hold the red power key for 1 second. T roubleshooting If you hav[...]

T o 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. Y ou can quickly scroll through the pages in either direction using the P AGE or QUIT keys. Let’ s briefly tour each of these pages in order to give you some insight into how they help you navigate. W e’ll[...]

Let’ s start with the Satellite Status Page, which is the page you’ll view while your unit is getting a position fix. If you’re not already on this page, press P AGE or QUIT until it appears. The Satellite Status Page shows you status information that helps you understand what the receiver is doing at any given time, and it’ s a page that y[...]

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’r e moving, while six user -selectable data fields belo[...]

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 desi[...]

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 gr eater emphasis on the straight-line desired course and the dis[...]

The GPS III+’ s Highway Page also provides graphic steering guidance to a destination waypoint. As you head toward your destination, the middle of the screen provides visual guidance to your waypoint on a moving graphic “highway .” Y our present position is at the bottom center of the highway display . The line down the middle of the highway [...]

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 de[...]

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. Y our GPS III+ can hold up to 500 waypoints. T o mark your present position: 1. Press and hold the ENTER/MARK key. The Mark Waypoint Page will appear , with a default three-digit nam[...]

Once you’ve stored a waypoint in memor y , 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 ma[...]

T o 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. T o cancel the current GOTO destination: 1. Press GOTO. 2. Press MENU. 3. Highlight ‘Cancel GOTO’ and press ENTER. [...]

The GPS III+ is a powerful navigation system providing detailed mapping informa- tion in a convenient, compact package.

Select a five mile scale by pressing zoom IN or OUT repeatedly . W orking from the Map Page is a simple process that centers around the use of a reference “arrow”. Controlled by the rocker keypad, the reference arrow is an important tool allowing you to pan to other areas on the map display , create waypoints, view waypoint information and crea[...]

4. A city symbol is assigned to the new waypoint, but let’ s use a special symbol to identify it. Highlight the waypoint symbol field, using the rocker keypad, and press ENTER. Use UP/DOWN on the rocker keypad to select the ‘Information’ icon (‘?’) and press ENTER. 5. T o save the new waypoint, highlight ‘Done’ with the rocker keypad [...]

T o 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. Let’ s call our present position ‘HOME’. (If you were at home when you initialized your GPS III+, you might want to keep this waypoint in memor y[...]

Notice the information on the map display is slowly moving? That’ s how it would look in actual use as well. The background map information and nearby waypoints will move across the screen, while your current position remains fixed in the center . The other primary navigation screens are the Compass and Highway pages, with the Compass Page appear[...]

T o view the Highway Page, press P AGE. The Highway Page pr ovides a graphic highway display that shows your movement relative to the desired course. The line down the middle of the highway represents your desired course. As you navigate toward your destination, the highway will actually move, indicating the dir ection you’re off course. T o stay[...]

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) un[...]

Y ou can use the sky view to help determine if any satellites are being blocked, and whether you have a current position fix (indicated by a ‘2D Navigation’ or ‘3D Navigation’ in the status field). Y ou can also set the sky view to a ‘T rack Up’ configuration, causing the top of the sky view to align along your current track heading. Wh[...]

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. T ur n the unit off and back on to reset, and reinitialize the receiver if necessary . Simulating Nav — the rec[...]

‘AutoLocate’ forces the r eceiv- er to search for all satellites (twelve at a time) until enough satellites are found to determine a position.

DOP measures satellite geometry quali[...]

With 2D coverage, you will need to enter your approx- imate altitude. Without an appr oximate altitude, your position error can be sub- stantial.
