INTRODUCTION Welcome to the exciting world of GPS! Whether you’re a first-time user or a professional navigator, you’ll find the GlobalNav 12 is a full-featured GPS receiver at a price that was impossible just a few years ago. The ® Rockwell receiver built inside has 12 channels that will track all of the satellites that are in view of your location. It’s acquisition time and tracking ability are second to none in its class. The Global Positioning System (GPS) was developed by the United States

S/A - 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 horizontal

GETTING STARTED Power The Expedition operates from four AA batteries, or one DURACELL® NiMH rechargeable battery, or from 5 to 16 volts DC using the external power cable. If the power cable is used, the Expedition automatically switches to it if the external power is greater than the battery voltage. If for any reason the external power fails, the unit automatically switches to the batteries. BATTERIES The unit requires four AA batteries. We recommend you use alkaline bat- teries for the best tr

Replace the compartment cover and follow the charging instructions included with the BR-1. (Note: The DR-121 is the only battery that can be recharged in this unit! Using the ex- ternal power cable alone does not charge the battery! You must use a charger supplied by Eagle in order to charge the battery. Also, this charger will only charge a DR-121. It will not charge any other type of battery, including ni- cads or rechargeable alkallines.) External Antenna Although this GPS receiver is extreme

show in addition to the normal menus. If the navigation screen is showing, and you press the MENU key, plotter menu items won’t show on the list. This helps you find the item you need without scrolling through unneces- sary menus. Turning Power On To turn the unit on, simply press the PWR key. A screen similar to the one at right appears. Read the message on the screen, then press the EXIT key to erase it or wait a few seconds and it automatically clears. The screen shown below appears next. Sat

quality the unit currently has. The smaller the expected error number, the better (and more accurate) the fix is. If the expected error is flashing, then the unit has not locked onto the satellites, and the number shown is not valid. A battery level indicator on the lower right side of the screen shows the approximately how much life is in the batteries. This runs from “F” (fully charged) to “E” (expired). A light bulb indicator at the top right corner of the screen appears when the backlights a

Quick Initialization If you don’t want to wait for the Auto Search, then you can speed up the initialization process by using the “Quick Initialization” feature. To do this, first turn the unit on, then press the MENU key. The screen shown at right appears. Now press the down arrow key until the “GPS SETUP” label is highlighted. Press the right arrow key.

The unit returns to the full initialization screen. Repeat this for each of the other settings until they’re correct for your location and time. Note: The position doesn’t have to be very accurate. If you enter a posi- tion within one degree of your actual location, the unit will be able to acquire the proper satellites. Press the EXIT key to erase the full initialization menu. The unit will use the data you entered to find the satel- lites that are currently in view. The receiver should lock on

distance you are off-course to the side of the desired course line. The course line is an imaginary line drawn from your position when you started navigating to the destination waypoint. It’s shown on the screen as a vertical dotted line. The default for the cross track error range is 0.25 mile. For example, if the present position symbol touches the right cross track error line, then you are .25 mile to the right of the desired course. You need to steer left to return to the desired course.

in the center. If you drift off course to the left, the line moves to the right. This signifies that you need to steer to the right to get back on course. This is called “chasing the needle”. If you steer towards the line (needle), you’ll always be heading in the correct direction to get back on course. The CDI’s range shows in the upper right corner of the CDI box. You can adjust the range by selecting the “ALARMS/CDI” label on the main menu. The default is 0.25 mile. This is also shown by the

Plot-3 (see at the top of the next page) is similar to plot-2. The major difference is the steering arrow and waypoint information at the bottom of the screen. When you navigate to a waypoint, the waypoint’s name and number show at the bottom of this screen. The steer- ing arrow always points in the direction to the waypoint. The Z-IN and Z-OUT keys zoom-in and out all plotters to enlarge or reduce their coverage area. The available ranges are: 0.1, 0.15, 0.2, 0.3, 0.4, 0.6, 0.8, 1, 1.5, 2, 3, 4

Plotter Orientation Normally, the plotter shows north at the top of the screen. This is the way most maps and charts are printed. This is fine if you’re travelling north- ward. Waypoints on the plotter’s left side should also be to your left, and so on. However, if you travel an

The course-up mode locks the top of the screen into the original bearing to the waypoint when navigation was first started. (See the navigation section for more information on course, track, and waypoint navigation.) To select a plotter orientation, highlight the “ROTATE” label on the “Plotter Options” menu. Press the right or left arrow keys until the desired mode appears. Press the EXIT key to erase the menu. PLOT TRAILS The line extending from the present position is your plot trail, or path

ICONS The plotter has 28 symbols or “icons” available that can be placed any- where on the screen. They can be used to mark fishing or hunting loca- tions, landmarks, boat ramps, and virtually any point of interest. An icon can be placed at your present position or at the cursor’s location.
