Carry Lanyard Attachment Slots 3 GPSmap 76C Getting Started Initialization & the Satellite Page Starting Up the GPS Receiver When you turn on the GPSmap 76C, the GPS receiver begins to search for satellites in order to determine (fix) its location. This process is called "initialization" and can take from 5 to 15 minutes the first time you use your unit. Thereafter, if you haven't moved more than 600 miles from your original location, it takes only seconds to minutes. In order to receive satellite signals, you must be outdoors and have a clear view of the sky. Satellite signals cannot pass through solid materials (except glass) or dense overhead tree cover. To shorten the time required for initialization, select "New Location" from the options menu, then use the Map Page to determine your general location so the GPSmap 76C can search for those satellites above you. To initialize your GPSmap 76C: 1. Press and release the POWER key to turn on the unit. 2. Observe the "Power On" Page followed by the Satellite Page. 3. While the GPS receiver is searching for the satellite signals, a "Locating Satellites" message is replaced by an "Acquiring Satellites" message until enough signals are acquired to fix its location. If the unit cannot get a satellite fix, a list of solutions appears. Highlight the appropriate solution and press ENTER. You can also observe a sky view array of the satellites overhead with your position centered in the array. The outer circle represents the horizon and the inner circle a position 45o from the horizon. The numbers displayed indicate the number assigned to each satellite. A bar graph at the bottom of the page displays the strength of signals from each satellite. The GPSmap 76C locates satellites above its position Heading Bug indicates your direction of movement. Options Menu Satellite Page Acquiring Satellite Signals 4 GPSmap 76C Getting Started 4. When the receiver has signals from at least three satellites, the display at the top of the page will change to indicate position accuracy and location coordinates. The Status Bar at the top of the display indicates the GPS status and status of other features. If, for any reason, you have difficulty initializing your GPSmap 76C, the solution could be as simple as moving slightly to avoid objects that are blocking or deflecting the satellite signals. 5. Press and release the PAGE key until the Map Page is displayed. You are now ready to begin GPS aided navigation. Active Navigation is supported by three of the Main Pages: Initialization & The Satellite Page Map Item Details Position Arrow Map Scale The Map Page graphically shows you map details, your current location, marks your route to a destination with a route line, and leaves a trail (track log) of where you've been. The Compass Page indicates direction to go and direction of travel. The Trip Computer Page records and displays travel data. There are three methods of navigating to a destination when using the GPSmap 76C', each graphically displayed on the Map Page. Go To - A direct path to a selected destination (waypoint, city, address, etc.). Track - A previous path of travel that has been stored (logged) in the GPSmap 76C. A Track allows you to repeat or retrace a path. Route - A path to a destination consisting of intermediate stops along the way (waypoints, cities, exits, points of interest, intersections, etc.). Refer to the sections on Tracks, Routes and Waypoints for details.

The Map Page displays a detailed map of the area surrounding your current location. It allows you to pan the map with the ROCKER key as well as view your progress when navigating. When in the "Track Up" mode (oriented in the direction of travel), a north reference arrow appears at the top left corner to orient the map. When in the "North Up" mode the map is oriented like a paper map. When you activate the Track Log feature, your path of movement is indicated by a dotted line. The map display can be changed to "Night" mode for easier viewing in dim light. The factory set default automatically changes the display at sunrise and sunset. The map also displays geographic details such as rivers, lakes, highways, towns and Tide Prediction Stations contained in the basemaps included with the unit. The maps to the left show a higher level of detail than the basemaps provided with the unit (i.e. residential streets, parks, etc.) because Garmin MapSource® detailed mapping data has been downloaded from a CD-ROM program. You can use the Map Page to: · Determine your current location and progress while moving. · Select and save a map point as a waypoint. · Locate and navigate to map items by following a Route displayed on the map. · Customize the map display to your requirements.

Map Declutter "Off" Map Declutter "On" 13 GPSmap 76C GPS Navigation The Compass Page Using the Compass Page The Compass Page is your guide to accurate and efficient navigation. It uses traditional navigation displays to provide navigation information. Whenever navigation is in progress, the Compass Page provides navigation data and directions. It uses a graphic compass display and a bearing pointer along with digital data fields to display information such as current speed, distance to the next point on the route, estimated arrival time, etc. You can choose from three or four data fields and select the type of data displayed in each from a list of options. When moving, the rotating graphic compass indicates the direction you are heading. The Bearing Pointer indicates the direction (bearing) to your destination, relative to your current heading direction. The compass dial and bearing pointer work independently to show your direction of movement and the direction to your destination. You can choose between a Bearing Pointer or a Course Pointer for guidance. The compass does not function as a magnetic compass when you are stationary. However when you move, the dial rotates to keep you oriented in relation to North. This is especially helpful when using a paper map in conjunction with your unit for navigation. The Compass Ring moves to indicate North orientation when you are moving. Compass Page The Course Pointer indicates your course of travel and the distance you drift off course. The Bearing Pointer always indicated the direction to your destination. Course Pointer Bearing Pointer 14 GPSmap 76C GPS Navigation To use the Compass Page Options: 1. Press the MENU key to display the Options Menu. 2. The first option is "Stop Navigation" which can be highlighted and activated by pressing ENTER to stop navigating. 3. The second option is "Course Pointer" or "Bearing Pointer". The Bearing Pointer and Compass Ring work independently of the direction of your movement and the direction to your destination. The Bearing Pointer always points directly to the destination, no matter what your current location might be. For example: if the arrow is pointing straight up, you are going directly to your destination. If it points any direction other than up, turn towards that direction until the arrow is pointing up and then continue in that direction. If you are using the `Course Pointer' option instead and you drift away from the line of travel to your destination, the Course Deviation Indicator (CDI) provides graphic indication of drift (right or left) and displays the distance off course. 4. The third option is "Data Fields". Highlight the data fields option and press ENTER to display the "Show: 3 Data Fields or 4 Data Fields" options. Highlight your selection and press ENTER. 5. The next option is "Change Data Fields" which allows you to determine what data is displayed in the fields. When you select this option, the topic of the first data field on the page will be highlighted. When you press ENTER, a list of data options will appear. Refer to page 11 for details on changing data fields.
