Magellan Meridian - Manual (Page 12)

4 Magellan Meridian GPS Receiver
The Meridian will walk you through the process of setting up the receiver
for first time use. This procedure is commonly referred to as “Initializing
the Receiver.” The purpose of this initializaion is to provide the Meridian
with a general knowledge of its approximate location.
This may seem a little confusing at first as why does a device that is used to
compute its position need to know where it’s at? The Meridian uses
information from the GPS satellites that orbit the earth and if the Meridian
has an approximate idea as to its location, it will refer to the almanac it has
in memory to select what satellites are overhead. From this information,
the Meridian can then select the satellites that will give it the best
information for computing its location. Under normal use, the Meridian
will save the last position it calculated and use that position the next time it
is turned on. However, when the Meridian is new (or when memory has
been completely erased), the Meridian has no last position information.
Thus, it can either start polling the satellites to see which ones are overhead
or you can provide it with your approximate location allowing the Meridian
to begin computing the initial position, known as “first fix.”
Note: You can skip the initialization process by pressing the [NAV] key
anytime after selecting the language you want the Meridian to use and
agreeing to the Warning Page. If the Meridian is able to collect satellite
data (i.e., have a clear view of the sky) it will begin to self-initialize.
This could take anywhere from 3 to 8 minutes to compute its initial
position.
Follow these instructions to initialize the Meridian.
Step 1: Turn the Meridian On
Press [PWR]
The Meridian turns on and displays the start-up
screen, followed by the language selection
screen.
