bAsIc operAtIon > InItIAlIzInG the Gps receIver
Initializing the GPS Receiver
The GPSMAP 76 needs to be initialized the rst time
the unit is used, if it has been stored several months,
or if it has been moved over 600 miles. The Almanac
within unit stores each satellite’s orbital data that is
supplied in the satellite signals. The GPSMAP 76 uses
the Almanac to know which satellites to search for
and automatically updates each time the unit aquires
satellites. If you do not use your GPS for several
months or move the unit over 600 miles between
uses, the Almanac can become “cold” and the orbital
information is no longer valid. Your unit may have
trouble locking on to satellite signals using a “cold”
Almanac. If the unit is unable to receive enough
satellite signals to determine its location and update the
Almanac, it displays an options menu.
Initializing the GPS Receiver:
1. With fresh batteries installed, take the unit
outside for a clear 360° view of the sky.
2. Turn the unit on and hold it in front of you with
the top of the unit tilted upward. Follow the
screen prompts, pressing PAGE to display the
GPS Information page.
3. The initialization process is automatic. It should
take the GPSMAP 76 no longer than ve
minutes to acquire enough satellite signals to
become operational. When the unit is able to
navigate, it displays either 2D GPS Location or
3D GPS Location in the Receiver Status eld.

bAsIc operAtIon > InItIAlIzInG the Gps receIver
Initialization Options
If the GPSMAP 76 is unable to determine its location,
an options menu is displayed. Select the appropriate
option to help the unit acquire satellites. Highlight the
option and then press ENTER to select.
Start Simulator—is used for practicing with the unit
while inside and satellite signals are not available.
When you select Simulator, the GPS receiver is turned
off saving battery power.
New Location—is used when you have moved the unit
over 600 miles and are having trouble locking onto
satellite signals.
When you select New Location, another menu is
displayed. This menu contains the options Automatic
or Use Map. If you select Automatic, the unit switches
to the AutoLocate mode and begin searching for
satellites. This process may take longer to acquire
satellites. Use Map utilizes the pointer on the Map
page to select your approximate location. Then the unit
continues to acquire satellites normally.
Stored w/o Batteries—is used when the date stored
in the unit may be incorrect due to storage without
batteries. To check the date, highlight Stored w/o
Batteries and verify the date displayed. If the date is
incorrect, select Stored w/o Batteries to search
for satellites.
Continue Acquiring—is used when in an area where
the satellite signals are being temporarily blocked.
When initializing the receiver or trying to
receive satellite signals, orient the GPSMAP
76 so the top of the unit points toward the
sky. If the unit is held with the top of the unit
pointed toward the horizon, satellite reception
may be severly degraded.

Satellite Strength Indicator Bars
The Satellite Strength Indicator Bars not only show the
strength of the signal being received, they also show
the status of the signal. The bars are either shaded with
a light gray or lled with solid black. The gray bar
represents the GPS is in the process of storing orbital
data it is receiving from the satellite signal. When the
bar turns solid black, the GPS is using the satellite
signal for navigation. A “D” in or above the bar means
that differential corrections (WAAS or DGPS) are
being applied to that satellite.
Date, Time, and Current Location
The GPS gets date and time information from the
satellites on-board atomic clock. When the GPS

AppendIx > WAAs And dGps
What is WAAS?
The Wide Area Augmentation System (WAAS) is an
F.A.A. funded project to improve the overall integrity
of the GPS signal. It is a space-based system that
broadcasts integrity information and correction data
as determined by ground reference stations. WAAS
testing completed in September of 2003 conrmed
an accuracy of 2 to 3 vertical meters throughout the
majority of the continental U.S. and portions of Alaska.
For more information, go to
http://gps.faa.gov/Programs/WAAS/waas.htm
Note: If you are using the GPSMAP 76 outside
of the U.S., it is recommended that you turn off
WAAS for the most accurate location x.
What is Differential GPS (DGPS)?
The U.S. and Canadian governments (among others)
have set up Differential GPS (DGPS) stations to
transmit correction signals. They are operational in
coastal areas and on many navigable river systems. The
DGPS system is available for use without a fee.
Please refer to the U.S. Coast Guard’s Web site
http://www.navcen.uscg.gov/ for locations and the
status of the differential sites. Using DGPS requires
additional equipment.

Loran TD System
LORAN C is a radio navigation aid operated and
maintained in the United States by the United States
Coast Guard. The name LORAN is an acronym for
“LOng RAnge Navigation.” The LORAN system
covers the entire United States and the U.S. Coastal
Conuence Zone. From the perspective of a mariner,
the system is used for ocean and coastal navigation. It
can be used as a supplemental system for harbor and
harbor approach navigation, and it is used for inland
navigation by recreational vehicles.
LORAN TD Feature
The LORAN TD (Time Delay) feature eases the
transition from using LORAN to using GPS. The
GPSMAP unit automatically converts GPS coordinates
to LORAN TDs for those who have a collection of
LORAN xes for favorite shing spots and other
waypoints recorded as TDs. You can display your
position as a TD or enter waypoints as TDs. The
accuracy to be expected from this conversion is
approximately thirty meters. When the unit is placed
in the LORAN TD format mode, it simulates the
operation of a LORAN receiver. Position coordinates
may be displayed as TDs, and all navigation functions
may be used as if the unit was actually receiving
LORAN signals.
Using the LORAN TD Format
When creating new waypoints using LORAN TD
coordinates, you must set the correct LORAN chain
number and secondary stations in the Setup TD eld
before storing the waypoint. After the waypoint
is stored in unit memory, it will always reference
the LORAN chain number and secondary stations
GPSMAP 76 Owner’s Manual 69
AppendIx > lorAn td
currently selected in the Setup TD eld. If you enter a
different LORAN chain number, change the secondary
stations or offsets in the Setup TD eld, the active
waypoint information will reect those changes. Since
the GPSMAP 76 does not rely on the LORAN signal
for navigation, it can reference a different GRI chain
and/or secondary stations and still navigate to the
location stored in memory.
The Location Format eld is accessed in the Main
Menu under the Setup option’s Location tab. The
‘LORAN TD Setup’ window contains the elds to
select the Loran GRI-Chain Number, Primary and
Secondary Stations, and TD Offsets.
If the active GRI Chain, Secondary Stations, or Offsets
are changed, all waypoints stored in the units memory
will update and reference the the new settings when
displayed as a LORAN TD. It is important to note that
the saved coordinates of the waypoint are not being
modied, they are only being displayed in reference to
the different GRI Chain, Secondary Stations or Offsets.
Remember that the GPS is not relying on the LORAN
signal for navigation. The GPSMAP 76 converts the
TD coordinate to a LAT/LON coordinate before storing
a waypoint to memory. The unit can navigate to a
converted TD coordinate anywhere in the world.
To setup Loran TD from the Main Menu:
1. Using the ROCKER, highlight the Location
Format eld on the Location tab and press
ENTER.
2. Highlight Loran TD, press ENTER. This
displays the LORAN TD Setup window.
3. To change the settings of any of the ve elds,
highlight the eld, press ENTER, select/enter
the desired setting then press ENTER.
4. When done, press the PAGE key to return to
the Main Menu.
