Getting Satellite SignalsAfter you turn on the GPSMAP 276C, the unit automatically beginssearching for satellites. The GPS page is displayed while the unitis gathering satellite signals and acquiring a fix, which should takeonly a few minutes. While the GPSMAP 276C is getting satellitesignals, the GPS page displays the status as “Acquiring Satellites.”It may take a few minutes to acquire satellites and display yourcurrent location on the map. Be patient as the unit acquires satellitedata. To get signals more quickly, be sure the antenna is raised to theup position shown in the image on page 1.GPS PageNOTE: While acquiring satellites, the Map page may display thewrong location, such as China. This does not mean your unit hasthe wrong data loaded; it simply means you need to wait a fewmore minutes to acquire satellites and find your current location.Viewing GPS Status with the GPS pageThe GPS page provides a visual reference of satellite acquisition,receiver status, and accuracy. The sky view and signal strength barsgive an indication of what satellites are visible to the receiver andwhether they are being tracked.As the receiver locks onto satellites, a signal strength bar appearsfor each satellite in view, with the appropriate satellite numberunderneath each bar. The numbers displayed below each barrepresent the particular satellite that is being received. Numbersabove 33 indicate WAAS satellites.The sky view shows a birds-eye view of the position of each satelliterelative to the receiver’s last known position. The outer circlerepresents the horizon (north up), the inner circle represents 45ºabove the horizon, and the center point represents a position directlyoverhead. You can also set the sky view to a Track Up configuration,causing the top of the sky view to align along your current trackheading. Press MENU to change the configuration of the sky view.A power source indicator shows the unit is operating off batterypower ( ), that the unit is charging ( ), or that anexternal power source is in use ( ).4 GPSMAP 276C Owner’s ManualGETTING STARTED > GETTING SATELLITE SIGNALS
