Initializing Your GPS 12 for First-Time Use
The GPS 12 typically acquires a position fast
enough that initialization is not required. However, ini-
tialization may be necessary for the following:
• 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
after the first few minutes.
The receiver is shipped from the factory in
AutoLocate™ mode, which enables the GPS 12 to
determine its location anywhere in the world. To speed
up the initialization process, we recommend using the
graphic initialization described below, which will usual-
ly provide a fix in a few minutes.
To turn the GPS 12 on:
1. Press and hold
B
until the receiver turns on.
The welcome page will be displayed while the unit
conducts a self test.
Once testing is complete, the welcome page will be
replaced by the Satellite Page, and the EZinitprompt
may appear prompting you to select one of two initial-
ization methods:
•Select Country––allows you to initialize the
receiver by selecting your present position from a
list of countries in the GPS 12’s internal database.
This typically provides a position fix in under three
minutes.
•Autolocate
TM
––allows the GPS 12 to initialize
itself and calculate a position fix without knowing
your present position. This usually provides a posi-
tion fix in 3-5 minutes.
If the EZinit prompt has not automatically
appeared on the Satellite Page:
1. Press the
E
key.
Note: If the EZinitprompt ever appears afteryou
have initialized the receiver (due to the antenna’s view
of satellites being obstructed by trees, etc.), highlight
the ‘NO RE-INIT’ selection with the arrow keypad and
press
E
.

The EZinit prompt will
automatically appear if
the receiver needs to be
initialized. The pro m p t
may also appear during
normal use if the antenna
is shaded, thereby block-
ing satellite reception.
