Getting Satellite Signals
After you turn on the GPSMAP 276C, the unit automatically begins
searching for satellites. The GPS page is displayed 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 displays the status as “Acquiring Satellites.”
It may take a few minutes to acquire satellites and display your
current location on the map. Be patient as the unit acquires satellite
data. To get signals more quickly, be sure the antenna is raised to the
up position shown in the image on page 1.
GPS Page
NOTE: While acquiring satellites, the Map page may display the
wrong location, such as China. This does not mean your unit has
the wrong data loaded; it simply means you need to wait a few
more minutes to acquire satellites and find your current location.
Viewing GPS Status with the GPS page
The GPS page 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 displayed 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 ( ).
