gps ii + 8/4/98 3:28 PM Page 1 What is GPS? What is GPS? GPS is a system of 24 satellites which circle the earth twice a day in a very precise orbit and transmit information to earth. The GPS II+ must continuously “see” at least three of these satellites to calculate your position and track your movement.
gps ii + 8/4/98 3:28 PM Page 2 Satellite Acquisition To prevent accidental battery power loss, the GPS II+ will automatically shut off 10 minutes after the last keystroke if the unit is not tracking at least one satellite and has not acquired a position fix. 2 Satellite Acquisition Because the GPS II+ relies on satellite signals to provide you with navigation guidance, the receiver needs to have an unobstructed, clear view of the sky for best performance.
gps ii + 8/4/98 3:28 PM Page 3 Battery Installation Battery Installation The GPS II+ operates on 4 AA batteries (not included), which are installed at the base of the unit. These batteries provide up to 24 hours of use. To install the batteries: Polarity Markings 1. Flip up the metal ring at the base of the unit, and turn the ring 90˚ counter clockwise. 2. Install the batteries (Fig. 3), and close the battery compartment door. 3.

The GPS II+ features five main pages which are linked together in a chain (Fig. 10). You can quickly scroll through the pages in either direction using the PAGE or QUIT keys. Let’s briefly tour each of these pages in order to give you some insight into how they help you navigate.
gps ii + 8/4/98 3:28 PM Page 11 Getting Started Tour Satellite Page Fig. 11 Let’s start with the Satellite 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 PAGE or QUIT until it appears. The Satellite Page shows you status information that helps you understand what the receiver is doing at any given time, and it’s a page that you’ll want to occasionally refer back to as you use your unit.
gps ii + 8/4/98 3:28 PM Page 12 Getting Started Tour Fig. 12a Position Page The Position Page (Fig. 12a) 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 an active destination selected. A graphic compass display at the top of the page shows your direction of travel while you’re moving, while five data fields below display your track and speed, a trip odometer, and your position and altitude.
gps ii + 8/4/98 3:28 PM Page 13 Getting Started Tour To rename the waypoint: 1. Use the keypad to highlight the name field, and press ENTER. 2. Enter the waypoint name ‘HOME’ (Fig. 13a), and press ENTER. (See p. 6 for data entry.) The ‘waypoint symbol’ field will become highlighted. Each waypoint may also be assigned a custom waypoint symbol for easy waypoint recognition on the map page. To change the waypoint symbol: Fig. 13a 1. Highlight the waypoint symbol field (Fig. 13b), and press ENTER. 2.
gps ii + 8/4/98 3:28 PM Page 14 Getting Started Tour Using the Position Page You can even time yourself with the GPS II+’s on-screen clock. Now that you’ve marked a position, it’s time to take a brisk walk using the Position and Map Pages to watch your every move. You should still be on the Position Page. To get the most from this tutorial, walk in a straight line for 3-4 minutes at a fast pace and watch the Position Page.
gps ii + 8/4/98 3:28 PM Page 15 Getting Started Tour Map Page The GPS II+’s next page, the Map Page, shows your movement as a real-time track log (an electronic breadcrumb trail that “flashes” at a map scale of less than 5 miles), and your present position as a diamond icon in the center of the map. Use the zoom keys (IN and OUT) to change the map scale until you see the waypoint you just created (‘HOME’). We’ll cover more about this page in the reference section. 1.
gps ii + 8/4/98 3:28 PM Page 16 Getting Started Tour Going To a Waypoint Once you’ve stored a waypoint in memory, you can use the GPS II+ to guide you to it by performing a simple GOTO. A GOTO is really nothing more than a straightline course from your present position to the destination you’ve selected. To see how it works, let’s try navigating back to our starting position, the HOME waypoint. Fig. 16a To select a GOTO destination: 1. Press GOTO. 2. Highlight the ‘HOME’ waypoint, (Fig.
gps ii + 8/4/98 3:28 PM Page 17 Getting Started Tour Compass Page Whenever you select a destination waypoint, the GPS II+ provides graphic steering guidance with the Compass Page (the default navigation page). The ‘compass ring’ in the middle of the page shows your direction of travel while you’re moving (indicated by the top of the ring), and the pointer arrow points to your destination (selected waypoint).
gps ii + 8/4/98 3:28 PM Page 18 Getting Started Tour Menu Page You’ve already seen the first four pages in action by acquiring satellites, marking a position, and navigating to a destination. The last page available from the main page sequence is the Menu Page (Fig. 18a), which provides access to the GPS II+’s waypoint management, route, and setup features. To view the Menu Page: Fig. 18a 1. Press PAGE. To select a menu option: 1. Highlight the desired field, and press ENTER (18b).
gps ii + 8/4/98 3:28 PM Page 19 Getting Started Tour Clearing the Track Log After you’ve practiced and used the GPS II+ for a few trips, you may find that your map display has become cluttered with track plots. To get a feel for how the map and track features work, let’s clear the track log (the plot points left on the Map Page) we’ve just created during the Getting Started tour. To clear the track log: 1. Scroll to the Map Page, and press ENTER. Fig. 19a 2.
gps ii + 8/4/98 3:28 PM Page 20 Reference Fig. 20a Fig. 20b 20 Satellite Page The GPS II+’s Satellite Page provides a visual reference of satellite acquisition and position. As the receiver locks onto satellites, a signal strength bar will appear for each satellite in view, with the appropriate satellite number (1-32) underneath each bar. The progress of satellite acquisition is shown in three stages: • No signal strength bars— the receiver is looking for the satellites indicated.
gps ii + 8/4/98 3:28 PM Page 21 Reference Sky View and Signal Strength Bars The sky view and signal strength bars give you an indication of what satellites are visible to the receiver, whether or not they are being used to calculate a position fix, and the signal quality. The satellite sky view shows a bird’s-eye view of the position of each available satellite relative to the unit’s last known position.
gps ii + 8/4/98 3:28 PM Page 22 Reference Fig. 22a Fig. 22b 22 Receiver Status and EPE Receiver status is indicated at the top left of the page, with the current horizontal accuracy (estimated position error, in feet or meters) at the top right. The status will be shown as one of the following conditions: Searching— the GPS II+ is looking for any available satellites in view (Fig. 22a). AutoLocate— the GPS II+ is initializing and collecting new almanac data.
gps ii + 8/4/98 3:28 PM Page 23 Reference 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. Simulator— the receiver is in simulator mode (Fig. 23a). EZinit Option Prompt The Satellite Page also provides access to the EZinit prompt whenever a position fix has not been calculated (Fig. 23b).
gps ii + 8/4/98 3:28 PM Page 24 Reference Battery Level Indicator The Satellite Page also features a battery level indicator, located to the left of the sky view, which displays the strength of the unit’s batteries (Fig. 24). The battery indicator will not appear if the receiver is operating off external power. Fig. 24 # ! The battery level indicator is calibrated for alkaline batteries. Ni-Cad and lithium batteries will display the battery level differently due to voltage differences.
gps ii + 8/4/98 3:28 PM Page 25 Reference Screen Backlighting The GPS II+’s backlight feature illuminates the screen display for a user-defined interval (the default is 15 seconds) after every keystroke. There are three stages of backlighting. When backlighting is on, a bulb icon will appear at the bottom left of the sky view (Fig. 25). To adjust the duration of the screen backlighting, refer to the operation setup section (see p. 75). To turn the screen backlighting on: 1.
gps ii + 8/4/98 3:28 PM Page 26 Reference The graphic compass display is designed to show your current track and doesn’t serve as a true magnetic compass while you’re standing still. 26 Position Page The second page in the GPS II+’s main page sequence is the Position Page. This page shows you where you are, what direction you’re heading, and how fast you’re going, and it’s most useful when you are traveling without an active destination waypoint.
gps ii + 8/4/98 3:28 PM Page 27 Reference The following user-selectable options are available on the Position Page: Trip Odometer (TRIP)— total distance traveled since last reset. Trip Timer (TTIME)— total (cumulative) time in which a ground speed has been maintained since last reset. Elapsed Time (ELPSD)— hours and minutes since last reset. Average Speed (AVSPD)— average speed traveled. Maximum Speed (MXSPD)— maximum speed traveled since last reset. Altitude (ALT)— vertical distance above sea level.
gps ii + 8/4/98 3:28 PM Page 28 Reference Maximum Speed Field To obtain the most accurate reading of average speed, keep in mind that due to the sensitivity of the GPS II+’s antenna, your maximum speed value may include the effects of rapid movement, such as swinging your arm while holding the unit. To reset the maximum speed field: 1. Highlight the ‘maximum speed’ field, and press ENTER. Fig. 28a 2. Press ENTER to confirm the ‘RESET?’ prompt (Fig. 28a).
gps ii + 8/4/98 3:28 PM Page 29 Reference Marking a Position The GPS II+ allows you to mark, store, and use up to 500 positions as waypoints. Waypoints serve as electronic markers that let you keep track of starting points, destinations, navaids, etc. A waypoint position can be entered by taking an instant electronic fix, by manually entering coordinates (see p. 34), or by referencing a bearing and distance to a known position (see p. 35). To mark your present position: 1. Press MARK.

To select a waypoint page: Use the function prompts on the left side of the waypoint definition page to review, rename, or delete stored waypoints and to create new waypoints manually. 1.
gps ii + 8/4/98 3:28 PM Page 32 Reference Nearest Waypoints Page The nearest waypoints page shows the nine nearest waypoints that are within 100 miles of your present position, with the bearing and distance noted for each waypoint (Fig. 32a). This page will also let you retrieve a waypoint definition page or GOTO a selected waypoint right from the list. To review the waypoint definition page of a selected waypoint: Fig. 32a 1. Highlight the desired waypoint. 2. Press ENTER.
gps ii + 8/4/98 3:28 PM Page 33 Reference Waypoint List Page The waypoint list page provides a complete list of all waypoints currently stored in the GPS II+ and their respective waypoint symbols. The total number of empty and used waypoints is also indicated. From the waypoint list page, you can retrieve a waypoint definition page, delete all user-defined waypoints, delete waypoints by symbol, or review and perform a GOTO to a selected waypoint (see p. 32). To delete all user-defined waypoints: Fig.
gps ii + 8/4/98 3:28 PM Page 34 Reference Fig. 34a Waypoint Definition Page The waypoint definition page lets you create new waypoints manually or review and edit an existing waypoint’s coordinates, symbols, and comments. It is also used to delete an individual waypoint from memory (see p. 38). To create a new waypoint manually, you’ll need to know its position coordinates or its approximate distance and bearing from an existing waypoint. To create a waypoint by entering coordinates: 1.
gps ii + 8/4/98 3:28 PM Page 35 Reference Reference Waypoints To create a new waypoint manually without knowing its position coordinates, you’ll need to enter its bearing and distance from an existing waypoint or your present position.

To delete a stored waypoint: 1. Highlight ‘DELETE?’, and press ENTER. 2. Highlight the ‘Yes’ prompt, and press ENTER.
gps ii + 8/4/98 3:28 PM Page 39 Reference Scanning Waypoints As you manually enter a waypoint’s name, the GPS II+’s waypoint scanning feature will automatically display the first numerical or alphabetical match of the character you have entered to that point. This helps eliminate the need to always enter a waypoint’s complete name. To scan waypoints from a waypoint field: 1. Highlight the waypoint name field, and press ENTER. 2. Press the left side of the keypad to clear the name field. 3.
gps ii + 8/4/98 3:28 PM Page 40 Reference Selecting a GOTO Destination The GPS II+ provides four ways to navigate to a destination: GOTO, MOB, TracBack, and route navigation. The most basic method of selecting a destination is the GOTO function, which lets you choose any stored waypoint as the destination and quickly sets a direct course from your present position. To activate the GOTO function: Fig. 40a 1. Press GOTO. 2. Select the waypoint you want to navigate to (Fig. 40a), and press ENTER.
gps ii + 8/4/98 3:28 PM Page 41 Reference Man Overboard Function The GPS II+’s man overboard function (MOB) lets you simultaneously mark and set a course to a position for quick response to passing positions. To activate the MOB mode: 1. Press GOTO twice. The GOTO waypoint page will appear with ‘MOB’ selected (Fig. 41a). 2 Press ENTER to begin MOB navigation (Fig. 41b). Fig. 41a The GPS II+ will now guide you to the MOB waypoint until the MOB GOTO is cancelled.
gps ii + 8/4/98 3:28 PM Page 42 Reference TracBack Navigation GARMIN’s patented TracBack feature allows you to quickly retrace your path using the track log automatically stored in the receiver. This feature eliminates the need to mark waypoints along the way and manually create and activate a route back to where you began your trip. You may select one of three track recording options: Fig. 42a Off—no plot will be recorded. Fill—a track plot will be recorded until track memory is full.
gps ii + 8/4/98 3:28 PM Page 43 Reference To activate a TracBack route: 1. Press GOTO, highlight ‘TRACBACK?’ (Fig. 43a), and press ENTER. Fig. 43b Fig. 43a Once the TracBack function has been activated, the GPS II+ will take the track log currently stored in memory and divide it into segments called legs (Fig. 43b). Up to 30 temporary waypoints will be created to mark the most significant features of the track log in order to duplicate your exact path as closely as possible.
gps ii + 8/4/98 3:28 PM Page 44 Reference Tips on Creating and Using the TracBack Feature To get the most out of the TracBack feature, remember the following tips: • Always clear your track log at the exact point that you want to go back to (trail head, truck, dock, etc.). • The ‘record’ option on the track log setup page can be set to either the ‘wrap’ or ‘fill’ positions (see p. 42). • There must be at least two track log points stored in memory to create a TracBack route.
gps ii + 8/4/98 3:28 PM Page 45 Reference TracBack Tips (cont.) • If the receiver is turned off or you lose satellite coverage during your trip, the TracBack route will simply draw a straight line between any point where coverage was lost and where it resumed. • If the changes in direction and distance of your track log are very complex, 30 waypoints may not be enough to accurately mark your exact path.
gps ii + 8/4/98 3:28 PM Page 46 Reference Route Definition Page The last form of navigating to a destination with the GPS II+ is by creating a user-defined route. The GPS II+ lets you create and store up to 20 routes of 30 waypoints each. C B D A Fig. 46 46 The route navigation feature lets you plan and navigate a course from one place to another using a set of pre-defined waypoints.
gps ii + 8/4/98 3:28 PM Page 47 Reference Route Definition Page (cont.) The right side of the route definition page features several ‘function’ fields which let you copy, clear, invert, or activate the displayed route. Routes 1-19 are used as storage routes, with route 0 always serving as the active route you are navigating. If you want to save a route that’s currently in route 0, be sure to copy it to another open route, as it will be overwritten by the next route activation.
gps ii + 8/4/98 3:28 PM Page 48 Reference Creating and Navigating Routes To create a route from the route definition page: 1. Highlight the ‘route number’ field, and press ENTER. 2. Enter a route number, and press ENTER. (Only open routes will be available.) 3. Press ENTER to begin entry of a route comment, if desired (Fig. 48a). Fig. 48a 4. Enter your comment, and press the ENTER key. 5. Enter the first waypoint of your route, and press ENTER.
gps ii + 8/4/98 3:29 PM Page 49 Reference Activating and Inverting Routes After a route has been entered, it can be either activated in sequence or inverted from the route definition page. The process of activating or inverting a stored route takes a storage route (routes 1-19) and copies it into the active route (route 0) for navigation. The storage route is now no longer needed and will be retained in its original format under its existing route number.
gps ii + 8/4/98 3:29 PM Page 50 Reference Fig. 50a Active Route Page Once a route has been activated, the active route page will display the waypoint sequence of your route with the estimated time enroute (ETE) at your present speed and the distance to each waypoint (Fig. 50a). As long as you are navigating an active route, the active route page will become part of the main page sequence of the unit.
gps ii + 8/4/98 3:29 PM Page 51 Reference Copying and Clearing Routes The route definition page is also used to copy a route to another route number. This feature is useful when you make changes to the active (or TracBack) route and want to save the route in its modified form for future use. To copy a route: 1. Highlight the ‘route number’ field, and press ENTER (Fig. 51a). 2. Enter the route number to be copied, and press ENTER. Fig. 51a 3. Highlight the ‘copy to’ field, and press ENTER. 4.
gps ii + 8/4/98 3:29 PM Page 52 Reference Editing Routes Once a route has been created and stored, it can be edited at any time. To edit a route from the active route page or the route definition page: 1. Select the waypoint you want to edit, and press ENTER (Fig. 52a). Fig. 52a Fig. 52b 52 An on-screen menu of editing choices will appear, with options for reviewing, inserting, deleting, or changing the waypoint field highlighted (Fig. 52b).
gps ii + 8/4/98 3:29 PM Page 53 Reference On-Route GOTOs At the beginning of this section, we mentioned that the GPS II+ will automatically select the route leg closest to your position as the active leg. This will give you steering guidance to the desired track of the active leg. Note that the first waypoint selected as the destination waypoint will be of the route leg closest to your present position.
gps ii + 8/4/98 3:29 PM Page 54 Reference Fig. 54a Fig. 54b 54 Selecting a User-Defined Navigation Page Once you’ve selected a GOTO destination or activated a TracBack, MOB, or route, the GPS II+ will provide graphic steering guidance to the destination with one of two navigation pages: •The Compass Page (default) provides a directional pointer to the destination, with a rotating compass display to show your direction of travel (Fig. 54a).
gps ii + 8/4/98 3:29 PM Page 55 Reference Selecting a User-Defined Navigation Page (cont.)
