Initialization for First-Time Use
MobileMapper Pro’s software will walk you through the pro-
cess of setting up the receiver for first time use. This proce-
dure is commonly referred to as “Initializing the Receiver.”
The purpose of this initialization is to provide MobileMapper
Pro with a general knowledge of its approximate location.
It may seem a little confusing that a device that is supposed
to compute its own position must first be told where it is. The
truth is that the receiver does not need to be told where it is,
but selecting an approximate location the first time will allow
the receiver to compute its position more quickly. You do not
have to type in coordinates because the software will let you
select a geographic location that is closest to your country,
state or province. Once you do this, a file preloaded into the
receiver during manufacture - called an almanac - will tell the
receiver which GPS satellies are currently orbiting overhead.
The receiver then looks only for these satellites when calculat-
ing its first location.
Under normal use, MobileMapper Pro will save the last posi-
tion it calculated and use it the next time it is turned on to
quickly estabish a first fix. In most cases, therefore, Mo-
bileMapper Pro does not need to be initialized when it is
turned back on. However, you should initialize your receiver
when it is new, has not been used for several months, has
been moved several hundred kilometers since its last fix or
when you have cleared its memory (such as when you upload
a new version of software).
Follow these instructions to initialize MobileMapper Pro:
1. Turn MobileMapper Pro on by pressing the PWR
button. The unit turns on and displays the start-
up screen, followed by the Database Copyright
screen and the language selection screen.
2. Select your language using the up/down arrow to
move the cursor to this language. With the
desired language highlighted, press the ENTER
button.
Skipping Initialization
You can skip the initial-
ization process by
pressing the NAV key
anytime after selecting
the language you want
MobileMapper Pro to
use and accepting the
agreement. If
MobileMapper Pro is
able to collect satellite
data (i.e., have a clear
view of the sky) it will
begin to self-initialize.
It could take anywhere
from 3 to 14 minutes
to compute its posi-
tion, depending on how
many weeks have
elapsed since it was
last used.
