A CAREFUL NAVIGATOR NEVER RELYS ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION This GPS receiver,(like all GE'S navigation will show the shortest, most direct path to a waypoint.equipment) It provides navigation data to the waypoint regardless of obstructions.

NOTES: INTRODUCTION The GlobalNav represents one of the best values in GPS receivers today. It rivals other GPS units costing much more in both features and performance. The GlobalNav offers easy-to-use operation at the touchof a button. Although the GlobalNav has many features and functions, the "soft key" menu systemmakesit easy to use. Above all, don't be afraid to try different features and functions on the unit.
possible. For example, if you haveto extendthe power cable to the battery or power buss, attach the fuse holder directly to the battery or power buss. This will protect both the unit and the powercable inthe eventof a short. Thewhitewire is for a NMEA interface. The GlobalNavsendsdata for anotherelectronic navigation devices through this wire. If the white wire is not used, tape the end so that it cannotshort.
See the NMEA section in this manualfor more information. The GlobalNav automatically sends NMEA data out the while wire once it acquires and 'locks on" to the satellites. GPS MODULE INSTALLATION The GPS module can be installed on a flat surface or (with the suppliedadapter) on a pole. Mount the module in an area that guarantees a clear view of the sky at all times. In order for the module to receive the signals from the satellites, it must not be obstructed. An ideal location is on a cabin roof, or deck.
Surface Mounting - Without Access If you don't have access to the back side of the mounting sur- usethe "cleats" suppliedwith theGlobalNav. (Note:This is assuming you can "snake" the module's cable to a locationthat is accessable. A hole will still need to be drilled in the mounting surfaceforthe cable.) Using the gasket as atemplate, mark and drillthe 9/16" holefor the cable. Attachthe cable to the module face1 and drop the other end of thecablethroughthegasket and down the hole.

key adjacent to the "Use Position" label. The Globalwavreturns to the last used position, navigation, or plotter screen using the offset information you entered. To verify that PCF is in effect, switch to the position, navigation, or plotter screen. The letters "PCF" appearon these screens when POF is enabled. WAYPOINTRECALL- This key is usedto recall waypointsfrom memory. CLEAR - Use this key to exit from menus OFF - The Off key turns theGlobalNavoff.
As the receiver lacks on to each satellite, it calculates the distance from the satellite by measuring the length of time it takes the radio signal to reach it. The satellites have an extremely accurate clock and it tells the receiverwhen the radio transmission started. The receiver compares that time against its own clock, thus it knows how long it lookthe radio signal (travelling at thespeed of light!) to reach it. If you know time and speed, then you can calculate distance.
SYSTEM INFORMATION The codecontainedin the GlobalNav is numbered. This informalion can be obtained by pressing the MENU key, lhen the key adjacent to the MORE label two times. Next, press the key adjacentto the"System Info" label. A message similarto theone below will be displayed. GlobalNav Version: 1.0 Copyright 1991 Lowrance Electronics Pressthe key adjacent totheCLEAR label to erase this message and return to the sonar screen.
If you need to change any of this data, press the key adjacent to the "Change"label. The very first time you use the GlobalNav, you'll need to press this key. After pressing it, the screen shown belowappears.

DISPLAY CONTRAST The contrastof the display can be changedfor easier readingin differentlight conditions. To change the contrast, press the MENU key. Next, press the key adjacent to the MORE labelthree times. Now press the key adjacent to the Display Contrast label. The Disp. menu appears. Press the key adjacent to the up arrow to increase the display contrast. The key adjacent to the down arrow decreasesit. The bar graph changes with your selection. The numberin the menu box also changes.

For example, Eastern DaylightSavings Time becomes +6:00. Remember10 changeboth local time and Time Zone when changingto or from DaylightSavingsTime.
The unit of measure for all of the items on this menu are shown on this screen. To change one or all, simply press the key adjacent to the label that you wish to change. For example, to change Distance from miles to nautical miles, pressthe key next to the 'Distance"label until thelabel reads "Distance = NM." You can change the units of measure for all of the items on this screen at the same time. When you've modified the units of measureto the desired settings, press the CLEAR key.

The screen on the opposite page appears. Press the key adjacent to the up arrow in the XTE alarm's menu to increase the alarm's range. Press the key next to the down arrow to decreaseit. The XTE alarm's range is from .01 to 10 miles. ___I IJ___o__. .
GPS ALARMS The GlobalNavhasIwo GPS alarms; a CDI alarm arid an Arrival alarm. The CDI alarm sounds an audible tone when the CDI indicator moves past a preset limit. Both alarms are set and adjustedfrom thesame menu. ARRIVAL ALARM The arrival alarm sounds a tone when your positionis within the alarm's radius of a waypoint. For example, if the alarm's setting is .5 mile, then the alarm sounds a tone when you come within .5 miles of a waypoint.
Position Display The Position display shows your present position in latitude/ longitude coordinates. This is displayedin degrees,minutes,and thousands of a minute. (Not seconds.) Beneath the present position display is Course Over Ground (COG), Gross Track Error (XTE), Distance To Go (DTG), and Bearing to waypoint (BRG). Gross Track Error, Distance To Go, and Bearing are used only when a waypoint is recalled. See the section on waypointsfor more information.

Your present position appears near the top of the screen. Beneath this and to the left are the GOOP and HDOP displays. GDOP stands for Geometric Dilution Of Precision. This is a crossing angle indicator. It showsthe combination value of horizontal (HOOP), vertical (VDOP), and Time (TDOP). The smaller the GOOP number is, the better the crossing angles are. The GPS receiver selects satellites based on GDOP, therefore it always tries to use satellites that will result in good crossing angles.
