Section 3 contains short, easy-to-scan GPS lessons that follow one an-
other in chronological order. They're all you'll need to know to find your
way on the water or in the wilderness quickly.
After you've learned the basics (or if you already have some GPS expe-
rience), you may want to try out some of the GlobalMap 4800's many
advanced navigation features. That brings us to Section 4, Advanced
GPS Operations. This section contains the rest of the unit's GPS com-
mand functions, organized in alphabetical order.
When you come to a GPS menu command on the GlobalMap 4800's screen,
you can look it up in the manual by skimming over the table of contents,
just flipping through Section 3 or scanning through the command portion of
Section 4.
This unit is ready to use right out of the box, but you can fine tune and cus-
tomize its operation with dozens of options. We describe how to use general
system options along with GPS options in Section 5, System Setup and
GPS Setup Options. Section 5 is organized in alphabetical order.
In Section 6, we go into more detail on one of the GlobalMap 4800's
most remarkable capabilities — Searching. We'll introduce a search
example in the Basic GPS Operation section, but there are so many
map items you can search for, we had to give this function its own sec-
tion in the manual! For example, did you know this unit can look up
business phone numbers, functioning as a virtual Yellow Pages? We’ll
show you how in Section 6.
Finally, in Section 7, we offer Supplemental Material, including a list of
the GPS datums used, warranties and customer service information.
Now, if you're into the fine details, glance over the next segment on speci-
fications to see just how much GPS power your GlobalMap 4800 contains.
It's important to us (and our power users), but, if you don't care how many
watts of power the unit has, or how many waypoints it can store, skip
ahead to important information on how our GPS works, on page 4.
