GPSMAP 276C Owner's Manual v INTRODUCTION > CAUTION Caution Failure to avoid the following potentially hazardous situations may result in injury or property damage. The GPSMAP 276C is designed to provide you with route suggestions. It does not reflect road closures or road conditions, traffic congestion, weather conditions, or other factors that may affect safety or timing while driving. Use the GPSMAP 276C only as a navigational aid. Do not attempt to use the GPSMAP 276C for any purpose requiring precise measurement of direction, distance, location, or topography. The Global Positioning System (GPS) is operated by the United States government, which is solely responsible for its accuracy and maintenance. The government's system is subject to changes which could affect the accuracy and performance of all GPS equipment, including the GPSMAP 276C. Although the GPSMAP 276C is a precision navigation device, any navigation device can be misused or misinterpreted and, therefore, become unsafe. Map Data Information: One of the goals of Garmin is to provide customers with the most complete and accurate cartography that is available to us at a reasonable cost. We use a combination of governmental and private data sources, which we identify in product literature and copyright messages displayed to the consumer. Virtually all data sources contain inaccurate or incomplete data to some extent. This is particularly true outside the United States, where complete and accurate digital data is either not available or prohibitively expensive. vi GPSMAP 276C Owner's Manual GETTING STARTED > UNIT OVERVIEW GETTING STARTED Unit Overview The GPSMAP 276C is an all-in-one, versatile color chartplotter and automobile navigator--perfect for land or water. This portable GPS navigator features a 256-color TFT display that is easy to read in bright sun, a built-in basemap, and auto routing to provide you with automatically generated turn-by-turn directions. GPS antenna Detachable antenna collapses for storage. Be sure the antenna is up (as shown here) to receive satellite signals. See the Appendix, page 106, for instructions on removing the antenna. 256-Color TFT display with backlighting Battery pack. Press tab down to remove battery pack for replacement, if necessary. Backlit keypad for easy nighttime operation External power connector under USB connector weather cap under weather cap Slot for optional data card Serial number GPSMAP 276C Owner's Manual 1 GETTING STARTED > CHARGING THE GPSMAP 276C Charging the GPSMAP 276C Before using the unit, you might need to charge the battery in the GPSMAP 276C.

See the image on page 1 for connector location. 2. Align the notches and push the plug into the connector until fully seated. 3. Plug the 12 Volt adapter into an available AC outlet, or cigarette lighter receptacle if you have a cigarette lighter adapter. Use care when routing the cable; be certain that it does not interfere with vehicle operation. If you do not want to use the unit, but you would like to charge the battery, you can put the unit into Charge Mode. Connect the unit to an external power supply. Press and hold the POWER key. Instead of completely turning off, the unit now goes into Charge Mode. To charge the unit's battery: Charge Mode The unit begins charging as soon as external power is applied. Placing the unit in Charge Mode charges the unit more quickly than when the unit is turned on and reduces draw on the vessel or vehicle battery. NOTE: While in Charge Mode, the unit draws a small amount of current from the vessel or vehicle battery. To avoid discharging the vehicle's battery, disconnect the external power cable from the GPSMAP 276C when not in use for several days. Information About Charge Mode Applying external power to the GPSMAP 276C automatically turns on the unit for full operation. If the battery is present and needs to be charged, the external power source charges the battery while the unit is in use. 2 After using the unit a lot, you might notice that the lithium-ion battery in the unit is not holding a charge any more. This is common for lithium-ion batteries. Contact Garmin or your Garmin dealer to order a battery pack replacement if you are experiencing charging issues with your battery. GPSMAP 276C Owner's Manual GETTING STARTED > TURNING ON THE GPSMAP 276C Turning On the GPSMAP 276C The first time you turn on your new GPSMAP 276C, the GPS receiver must collect satellite data and establish its current location.

GPSMAP 276C Owner's Manual Backlight adjustment slider Volume adjustment slider 3 GETTING STARTED > GETTING SATELLITE SIGNALS Getting Satellite Signals After you turn on the GPSMAP 276C, the unit automatically begins searching for satellites. The GPS page appears while the unit is gathering satellite signals and acquiring a fix, which should take only a few minutes. While the GPSMAP 276C is getting satellite signals, the GPS page shows the status as "Acquiring Satellites." It might take a few minutes to acquire satellites and display your current location on the map. To get signals more quickly, be sure the antenna is raised to the up position shown in the image on page 1. Viewing GPS Status with the GPS Tab The GPS tab on the Main Menu provides a visual reference of satellite acquisition, receiver status, and accuracy. The sky view and signal strength bars give an indication of what satellites are visible to the receiver and whether they are being tracked. As the receiver locks onto satellites, a signal strength bar appears for each satellite in view, with the appropriate satellite number underneath each bar. The numbers below each bar represent the particular satellite that is being received. Numbers above 33 indicate WAAS satellites. The sky view shows a birds-eye view of the position of each satellite relative to the receiver's last known position. The outer circle represents the horizon (north up), the inner circle represents 45º above the horizon, and the center point represents a position directly overhead. You can also set the sky view to a Track Up configuration, causing the top of the sky view to align along your current track heading. Press MENU to change the configuration of the sky view. A power source indicator shows the unit is operating off battery power ( ), that the unit is charging ( ), or that an external power source is in use ( ). GPS Tab NOTE: While acquiring satellites, the Map Page may show the wrong location, such as China. This does not mean your unit has the wrong data loaded; it means you need to wait a few more minutes to acquire satellites and find your current location. 4 GPSMAP 276C Owner's Manual GETTING STARTED > GETTING SATELLITE SIGNALS Signal strength bars Receiver status field Sky view Power source indicator GPS Status The progress of satellite acquisition is shown in three stages: · No signal strength bars--the receiver is looking for the satellites indicated. · White signal strength bars--the receiver has found the satellite and is collecting data. · Green signal strength bars--the receiver has collected the necessary data from this satellite. When the GPSMAP 276C collects the necessary data from the best satellites in view to calculate a fix, the status field indicates the status of the receiver. The unit then updates the location, date, and time. Receiver Status The Receiver Status field shows one of the following conditions: · Searching the Sky--the receiver is looking for satellites. GPSMAP 276C Owner's Manual · AutoLocate--the receiver is looking for any satellite whose almanac was collected, which can take up to five minutes. · Acquiring Satellites--the receiver is looking for and collecting data from satellites visible at its last known or initialized location but has not acquired a fix. · 2D GPS Location--At least three satellites were acquired and a two-dimensional position fix was calculated. "2D Differential" appears when you are receiving DGPS corrections in 2D mode, and a "D" appears on the strength bar of satellites being corrected. · 3D GPS Location--At least four satellites were acquired and a three-dimensional fix was calculated. "3D Differential" appears when you are receiving DGPS corrections in 3D mode, and a "D" appears on the strength bar of satellites being corrected. · Lost Satellite Reception--the receiver is no longer tracking enough satellites for a 2D or 3D fix. · Receiver Not Usable--the receiver is unusable, possibly due to interference or abnormal satellite conditions. Turn the unit off and back on to reset. · Simulating GPS--the receiver is in Simulator Mode. · GPS Off--the GPS receiver is turned off. 5 GETTING STARTED > GETTING SATELLITE SIGNALS GPS Options Press MENU twice to open the Main Menu.

GPSMAP 276C Owner's Manual 23 BASIC OPERATION IN MARINE MODE > CREATING AND USING WAYPOINTS Waypoints are locations or landmarks you record and store in your GPS. They are locations you might want to return to later, such as checkpoints on a route or significant ground features. You can add waypoints to routes and even create a Go To directly to the selected waypoint. Save your current location as a waypoint by pressing and holding ENTER/MARK. You can also find waypoints using the map or the Find menu, and then store them in the unit before ever leaving home. The GPSMAP 276C stores up to 3,000 alphanumeric waypoints with a user-defined icon, comment, elevation, depth, and temperature available for each waypoint. Waypoints can be created using three basic methods: · ENTER/MARK--allows you to quickly mark your present location. · Graphically--allows you to define a new waypoint location from the map display using the ROCKER. · Text Entry--allows you to enter a new waypoint's location coordinates manually. Creating and Using Waypoints Use the ENTER/MARK key to quickly capture your present location to create a new waypoint. You must have a valid position (2D or 3D) fix to mark your present location. You can determine the satellite fix by looking at the GPS tab on the Main Menu. To mark your present location: 1. Press and hold ENTER/MARK until the New Waypoint Page appears, and then release it.
