Glossar y INTRODUCTION 2 The GPS 48 is a powerful navigation tool that can guide you anywhere in the world. T o better understand its operation and capabilities, it may be helpful to review the basic terms and concepts briefly explained below .
3 INTRODUCTION Glossar y Estimated Time Enroute (ETE) The time left to your destination at your present speed. Grid Coordinate system that pr ojects the earth on a flat surface, using square zones for position measurements. UTM/UPS and Maidenhead formats are grid systems.
NORTH “ACTIVE FROM” WAYPOINT NORTH DTK CROSSTRACK ERROR BRG TRK GROUND SPEED DISTANCE “ACTIVE TO” WAYPOINT “ACTIVE LEG” Navigation Basics INTRODUCTION 4 The GPS 48 provides steering guidance and navigation information using degrees, a measurement measur ed in a clockwise direction fr om a north reference.
5 INTRODUCTION Keypad Usage & Data Entr y DA T A ENTR Y The arr ow keypad is used for all data entry . Use the U and D keys to select letters, numbers, and menu options; use the L and R keys to move the cur- sor forwar d or back- war d along the line.
Initializing Y our GPS 48 for First-Time Use The GPS 48 does not require initialization under normal day-to-day use. However , initialization may reduce the time it takes to compute a position fix after one of the following events: • After memory loss • When the receiver has been moved mor e than 500 miles with the power off.
T o initialize the receiver: 1. If the ‘COUNTRY’ option is not highlighted, press the D key repeatedly to move the field highlight to the ‘COUNTRY’ option. 2. Press the E key . 3. Use the D key to scroll through the list options until the country of your present location appears.
Primary Pages Before we start the tour , let’ s briefly look at the five primary information pages used for the GPS 48. Switch between pages by pressing either the Q or J keys. Satellite Page The Satellite Page shows satellite positions and signal strength.
Map Page The Map Page acts as a window . It allows you to view your position, the “path” you have traveled over , and nearby navaids, cities and waypoints. A diamond icon in the center of the screen repr e- sents your current position. As you move, you will see a thin line - called a track log - appear along the path you have just covered.
Getting Started T our Now that you’ve seen the primary pages, let’ s get started by taking a simple tour to show you the basics about using your GPS 48. The tour assumes that your unit has been turned on, initialized, and that none of the factory settings (units of measure, selectable fields, etc.
Using the Position Page W alk at a brisk pace for 3-4 minutes and watch the Position Page. The direction you are moving (track), your speed, trip distance, and altitude are shown on the upper half of the screen. The latitude and longitude of your position are displayed in the middle of the page, with the time of day shown below .
Highway Page The GPS 48’ s Highway Page pr ovides graphic steering guidance to a destination waypoint, with emphasis on the straight-line desired course, the distance and direc- tion you are of f course. As you head toward your destination, the middle of the screen pr ovides visual guidance to your waypoint on a moving graphic “highway .
Clearing a Cluttered Map Display After you’ve used the GPS 48 for a few trips, you may find that your map display has become a bit messy from keeping track of your every move. For practice, let’ s clean up the screen by clearing the track log (the plot points left on the Map Page) we’ve just created during the Getting Started tour .
Satellite Page The GPS 48’ s Satellite Page displays the status of vari- ous receiver functions. The status information will help you understand what the GPS 48 is doing at any given time, and will tell you whether or not the receiver has calculated a position fix.
If you travel over 500 miles with the r eceiver off, you may r einitialize the unit to your new posi- tion by using the EZinit featur e. T o access EZinit pr ess ENTER fr om the Satellite Status Page befor e any satellites ar e acquir ed.
Batter y Level, Backlighting & Emergency Erase REFERENCE 16 When backlighting is on, a bulb icon will appear on the Satellite Page. Use the icon to determine if backlighting is turned on during daylight hours. Upon activating the Emergency Erase Function, you will be asked to confirm your decision.
Position Page The second page in the GPS 48’ s primary page sequence is the Position Page. This page shows you where you are, what dir ection you’re heading, and how fast you’re going, and it’ s most useful when you are travel- ing without an active destination waypoint.
Position Page (cont) T o reset timer , speed measurement, or odometer: 1. Highlight the user -selectable field, and press E . 2. Press E to confirm or Q to exit.
19 REFERENCE Map Page Note: A map scale r epr e- sents the distance shown fr om the bottom to the top of the Map Page. For example, when viewing the 10 mile scale, the dis- tance r epr esented between the top of the scr een and bottom is 10 miles.
Marine Database The GPS 48 contains an updateable, marine database that displays city locations and nautical navaids on the moving map. Check the Garmin website for possible nautical navaid updates. City locations are depicted by a small square icon, cities are displayed at the zoom scale specified on the city setup menu (see page 26).
Marine Database (cont) Lit and unlit navaids are designated by the primary color . The navaid symbol will have the first letter in the primary color displayed in the symbol.
Zooming, Panning, and Configuring There are thr ee main functions you can perform from the Map Page— zooming, panning, and configur- ing (changing the map and track setup). Each of these functions has its own “field”, which may be selected and activated for use.
Zooming, Panning, and Configuring (cont.) From the waypoint definition page, you can also define how each individual waypoint is displayed on the map. The GPS 48 displays waypoints as a name with a corresponding symbol (e.g., “nearest fuel” and a gas pump symbol), a symbol only (e.
Using the Cursor to Mark and Go to (cont.) Y ou can activate a direct GOTO to any user waypoint or navaid displayed on the map. T o GOTO a user waypoint or navaid: 1. Highlight the user waypoint or navaid by panning the map cursor to the point and press E .
Map Setup Page and Orientation (cont.) • ’Nearest’— shows the nine nearest user waypoints to your position (black diamond) on the map. • ’Names’— displays the waypoint name for the nine nearest waypoints. • ’T rack Log’— displays and plots track points on the map.
Managing and Clearing the T rack Log The rest of the track setup window displays the per- centage of available memory currently used to store track log data, and a function fields to clear the track log memory . Note: Clearing the track log will not erase way- points.
Labels contain informa- tion about the navaid. Labels can be activated by panning the map cur- sor to the navaid or by r eaching the selected map zoom scale Navaid Setup Page The navaid setup page lets you select the zoom scale where navaids become visible on the map.
Selecting a User Defined Navigation Page Once you have selected a GOTO, T racback, MOB or route the GPS 48 will pr ovide navigation using one of two user defined navigation pages.
Selecting a User Defined Navigation Page (cont) The ‘ETE’ field, located in the middle-bottom of both pages, is a user -selectable field that allows you to display a variety of navigation values for your trip. T o access the user -selectable field: 1.
In this example, the Compass Page indicates that you ar e traveling in an easterly (91 degr ees) dir ec- tion and the destination waypoint is south (177 degr ees) of your curr ent dir ection of travel. Using the Compass Page The Compass Page provides better steering guidance than the Highway Page for travel at slower speeds (ex.
Using the Highway Page The GPS 48’ s Highway Page pr ovides graphic steer- ing guidance to a destination waypoint, with a greater emphasis on the straight-line desired course and the distance and direction you are of f course.
Marking a Position The GPS 48 allows you to mark and store up to 500 position as waypoints. A waypoint can be entered by taking an instant electronic fix, by manually entering coordinates (pg. 35), or by using the bearing and dis- tance to a known position (pg.
W aypoint Pages The GPS 48 has three waypoint pages that let you quickly manage up to 500 waypoints. These pages— nearest waypoints, waypoint list, and waypoint defini- tion—can be accessed through the Menu Page. T o select a waypoint page: 1. Access the Menu Page, and highlight a waypoint page option.
W aypoint List Page (continued) An options page will appear , asking if you want to delete all user -defined waypoints or if you want to delete waypoints by symbol type. 1. Highlight either ‘ALL ’ or ‘SYMBOL ’, and press E . If you highlight ‘SYMBOL,’ you’ll be asked to select a symbol.
The GPS 48’ s advanced waypoint planning fea- tur es allow you to cr eate new waypoints and prac- tice navigation without ever setting foot outside. If you cr eate a new way- point by entering coor di- nates fr om a map, you may want to r e-mark the waypoint’ s exact position once you get ther e.
Reference W aypoints (cont.) 1. From the waypoint definition page, highlight ‘NEW?’, and press E . 2. Enter a waypoint name, and press E . 3. Highlight the ‘REF’ field, and press E . 4. Enter a reference waypoint name (or leave the field blank to use your present position), and press E .

Selecting a GOTO Destination The GPS 48 provides four ways to navigate to a des- tination: GOTO, MOB, T racBack, and route navigation. The most basic method of selecting a destination is the GOTO function, which lets you choose any stored way- point as the destination and quickly sets a direct course from your pr esent position.
T racBack Navigation GARMIN’ s patented T racBack feature allows you to quickly retrace your path using the track log automati- cally stored in the receiver . This feature eliminates the need to mark waypoints along the way and manually create and activate a r oute back to where you began your trip.
Tips On the T racBack Feature • Always clear your track log at the exact point that you want to go back to (trail head, truck, etc.). • The ‘RECORD’ option on the track log setup page can be set to either the ‘WRAP’ or ‘FILL ’ positions.
Route Navigation The last form of navigating to a destination with the GPS 48 is by creating a user -defined route. The route navigation featur e lets you plan and navigate a course from one place to another using a set of pr e- defined waypoints.
Route Definition Page The GPS 48 lets you create and store up to 20 routes of 30 waypoints each. The bottom of the route definition page featur es several ‘function’ fields which let you copy , clear , invert, or activate the displayed route.
