INTRODUCTION > CARING FOR THE GPSMAP 376C
Caring for the GPSMAP 276C
The GPSMAP 276C case is constructed of high quality materials
and does not require user maintenance except cleaning.
Cleaning the Case
Clean the unit’s outer casing (except for the screen) using a cloth
dampened with a mild detergent solution and then wipe dry. Avoid
chemical cleaners and solvents that may damage plastic components.
Cleaning the Screen
The GPSMAP 276C screen should be cleaned using a soft, clean,

INTRODUCTION > CAUTION
Caution
Failure to avoid the following potentially hazardous situations may
result in injury or property damage.
The GPSMAP 276C is designed to provide you with route suggestions. It
does not reflect road closures or road conditions, traffic congestion, weather
conditions, or other factors that may affect safety or timing while driving.
Use the GPSMAP 276C only as a navigational aid. Do not attempt to use
the GPSMAP 276C for any purpose requiring precise measurement of
direction, distance, location, or topography.
Map Data Information: One of the goals of Garmin is to provide customers with the most complete and accurate cartography that is available to us at a reasonable
cost. We use a combination of governmental and private data sources, which we identify in product literature and copyright messages displayed to the consumer.
Virtually all data sources contain inaccurate or incomplete data to some extent. This is particularly true outside the United States, where complete and accurate
digital data is either not available or prohibitively expensive.
vi GPSMAP 276C Owner’s Manual
The Global Positioning System (GPS) is operated by the United States
government, which is solely responsible for its accuracy and maintenance.
The government’s system is subject to changes which could affect the
accuracy and performance of all GPS equipment, including the GPSMAP
276C. Although the GPSMAP 276C is a precision navigation device, any
navigation device can be misused or misinterpreted and, therefore, become
unsafe.

GETTING STARTED > TURNING ON THE GPSMAP 276C
Turning On the GPSMAP 276C
The first time you turn on your new GPSMAP 276C, the GPS
receiver must collect satellite data and establish its current location.
To ensure proper initialization, the GPSMAP 276C is shipped from
the factory in AutoLocate mode, which allows the receiver to “find
itself” anywhere in the world. Before you turn on the unit to start
initialization, be sure that the antenna is rotated up as shown on
page 1, and it has a clear and unobstructed view of the sky to receive
satellite signals.

GETTING STARTED > GETTING SATELLITE SIGNALS
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.
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.
GPS Tab
A power source indicator shows the unit is operating off
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.

The progress of satellite acquisition is shown in three stages:
• No signal strength bars—the receiver is looking for the
satellites indicated.
• White signal strength bars—the receiver has found the
satellite and is collecting data.
• Green signal strength bars—the receiver has collected the
necessary data from this satellite.
When the GPSMAP 276C collects the necessary data from the best
satellites in view to calculate a fix, the status field indicates the status
of the receiver. The unit then updates the location, date, and time.
Receiver Status
The Receiver Status field shows one of the following conditions:
• Searching the Sky—the receiver is looking for satellites.
• AutoLocate—the receiver is looking for any satellite whose
almanac was collected, which can take up to five minutes.
• Acquiring Satellites—the receiver is looking for and
collecting data from satellites visible at its last known or
initialized location but has not acquired a fix.
• 2D GPS Location—At least three satellites were acquired
and a two-dimensional position fix was calculated. “2D
Differential” appears when you are receiving DGPS
corrections in 2D mode, and a “D” appears on the strength bar
of satellites being corrected.
• 3D GPS Location—At least four satellites were acquired
and a three-dimensional fix was calculated. “3D Differential”
appears when you are receiving DGPS corrections in 3D
mode, and a “D” appears on the strength bar of satellites being
corrected.
• Lost Satellite Reception—the receiver is no longer tracking
enough satellites for a 2D or 3D fix.
• Receiver Not Usable—the receiver is unusable, possibly due
to interference or abnormal satellite conditions. Turn the unit
off and back on to reset.
• Simulating GPS—the receiver is in Simulator Mode.
• GPS Off—the GPS receiver is turned off.

GPS Tips
While the receiver is gathering information, your location on the
map might appear different from where you actually are located.
As soon as the receiver gathers enough satellite information, your
proper location appears on the map.
Any time you have traveled more than 600 miles with the GPS
receiver turned off, the receiver may take longer than normal to
initialize and find your location.
The GPS receiver can lose satellite signals due to interference from
such items as buildings, tunnels, and heavy tree cover. Monitoring
