Garmin 76s Manuale Proprietario

7

The Reference Manual will describe the Main Display Pages and their options 

in detail.  The Quick Start Guide described the process of navigating the Main 
Display Pages and the Option Menus.  While the Reference Manual will provide 
some direction on how to select an item, its main intention is to describe each 
Main Page and it’s Option Menu in detail.
Initializing the GPS Receiver

Before the GPSMAP 76S can be used for GPS navigation, the GPS receiver 

must be initialized.  The GPS receiver should only need to be initialized the first 
time the unit is used, or if it has been stored several months.

The GPSMAP 76S stores orbital data for each satellite in an Almanac.  The 

orbital data is supplied in the satellite signals.  Each time the unit receives satellite 
signals, the Almanac is updated.  This is how the GPSMAP 76S knows which 
satellites to search for.  If you do not use your GPS for several months, or move 
the unit several hundred miles between uses, the Almanac can become “cold”, 
that is to say that the orbital information is no longer valid. If the Almanac is 
“cold”, your unit may have trouble locking on to satellite signals.  If the unit is 
unable to receive enough satellite signals to determine its location, it will display 
an options menu. 

1.  With fresh batteries installed, take the unit outside where a clear 360° view 

of the sky can be obtained.

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 76S 

no longer than five minutes to acquire enough satellite signals to become 
operational.  When the unit is able to navigate, it will display either “2D GPS 
Location” or “3D GPS Location” in the Receiver Status Field.
