INITIALIZATION
Initialization is the preparation you do before the receiver is used for the first
time or after memory loss. lt should also be done when the receiver is moved
300 miles or more from its last position fix. You can enter only the initial
position and the current date and time, or you can completely customize how
the receiver displays information.
This section describes how to enter the initial position, time, and date. Once
they have been entered, the receiver will check its internal almanac to
determine which satellites are likely to be visible at its location. (An almanac
is a schedule of where each satellite in the system is at any time.) The receiver
will locate these satellites and display a first position fix within a few minutes,
if you are in an unobstructed environment. Once the receiver has obtained
its first position fix at first use or after a memory loss, the time to first fix will
be shorter.
Not initializing the receiver will greatly increase the time to first fix.
