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.

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.
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 ( ).
