Initializing Your GPS 48 for First-Time Use
The GPS 48 does not require initialization under
normal day-to-day use. However, initialization may
reduce the time it takes to compute a position fix after
one of the following events:
• After memory loss
• When the receiver has been moved more than
500 miles with the power off.
Additionally, it may be necessary to initialize the
unit the first time you use it, if it does not acquire a fix
in a few minutes.
The receiver is shipped from the factory in
AutoLocate™ mode, which enables the GPS 48 to
determine its location anywhere in the world. Another
method is the graphic initialization described below,
which usually provides a fix in a few minutes.
To turn the GPS 48 on:
1. Press and hold
B
until the receiver turns on.
The welcome page is displayed while the unit con-
ducts a self test, followed by a warning page.
Once testing is complete, the warning page is
replaced by the Satellite Page, with the EZinit prompt
ready for you to select one of two initialization
methods:
•Select Country––allows you to initialize the
receiver by selecting your present position from a
list of countries in the GPS 48’s internal database.
This method usually provides a position fix in a
few minutes.
•Autolocate
TM
––allows the GPS 48 to initialize
itself and calculate a position fix without knowing
your present position. This usually provides a posi-
tion fix in 3-5 minutes.
The EZinit prompt can be activated from the satel-
lite page by pressing the
E
key if the unit has not
acquired satellites.
Note: If the EZinit prompt appears after you have
initialized the receiver (due to the antenna’s view of
satellites being obstructed), highlight the ‘NO RE-INIT’
selection with the arrow keypad and press
E
.
