Turning On the GPSMAP 276C
The fi rst time you power up your new GPSMAP 276C, the receiver must collect satellite data and
establish its present position. To ensure proper initialization, the GPSMAP 276C is shipped from the
factory in AutoLocate mode, which allows the receiver to “ fi nd itself” anywhere in the world. Before you
turn on the unit to start initialization, be sure the antenna is rotated up as shown on page 1, and that it
has a clear and unobstructed view of the sky to receive satellite signals.
To turn On and Off the GPSMAP 276C:
1. Press and hold the red POWER key. When the unit powers on, a tone sounds and a Warning/
Information Page displays.
2 To acknowledge that you have read and understand the warning, press the
ENTER/MARK key to
continue.
3. To turn off the GPSMAP 276C, press and hold the red
POWER key again.
Initializing the GPSMAP 276C
As soon as you turn the GPSMAP 276C on, it begins searching for satellites in your area and should
acquire a fi x within a few minutes. At the top of the screen, the unit displays the status as “Acquiring
Satellites.” While viewing the GPS Tab of the Main Menu, a signal strength bar for each satellite the unit
is trying to acquire appears at the top of the screen with the satellite numbers displayed below each bar.
The progress of satellite acquisition is shown in three stages:
• No signal strength bars – the receiver is looking for the satellites indicated.
• Hollow signal strength bars – the receiver has found the indicated satellites and is collecting data.
• Solid signal strength bars – the receiver has collected the necessary data and the satellites are
ready for use.
Once the receiver has collected information from, and is fi xed on, at least three satellites, the unit is
“ Ready to Navigate” and the display automatically switches to the Map Page.
