Start-Up and Satellite Acquisition
Find a location where you have a clear view of the sky. If you
are starting up for the first time or you have moved over 600
miles since last using the GPSMAP 76CSx, it must initialize
(determine its location by searching for satellites that are in
position over your current location). Press MENU to open
the Satellite Page Options Menu and mark your approximate
location on the Map Page, so it looks for only those satellites
above your location.
1. Turn on the GPSMAP 76CSx by pressing and
releasing the POWER key. A Welcome Page briefly
appears before opening the Satellite Page.
2. On the Satellite Page, GPS messages appear at the
top of the page.
• “Acquiring Satellites” message appears as the
GPSMAP 76CSx begins to search for satellites
overhead.
• Your Location Coordinates appear when four or
more satellites are fixed (enough to determine an
approximate elevation as well as ground location).

MicroSD and Battery
Installation
A MicroSD Card is required to load optional MapSource
data. The MicroSD card is located in
the battery compartment. To install the
card, slide the card in until you hear a
click. Press down and slowly release to
remove the card.
The GPSMAP 76CSx requires two
AA batteries (not included), which are
located in the back of the unit under the
D-Ring. Alkaline or NiMH batteries
can be used (see the Owner’s Manual
for setting the battery type). Stored data
is not lost when batteries are removed.
Install the batteries, observing the proper
polarity. A polarity diagram can be
found molded into the battery compartment. Extensive use
of backlighting, WAAS, and key beep tones can significantly
reduce battery life.
