However, there are some fringe areas of the U.S., including parts of Alaska,

that do not yet receive robust WAAS coverage. Continued WAAS develop-

ment is planned to extend WAAS coverage in the years to come.

WAAS boosts the accuracy of land GPS navigation, but the system is de-

signed for aircraft. The satellites are in a fixed orbit around the Equator, so

they appear very low in the sky to someone on the ground in North Amer-

ica. Aircraft and vessels on open water can get consistently good WAAS

reception, but terrain, foliage or even large man-made structures can some-

times block the WAAS signal from ground receivers.

You'll find that using your GPS receiver is both easy and amazingly accu-

rate. It’s easily the most accurate method of electronic navigation available

to the general public today. Remember, however, that this receiver is only

a tool. Always have another method of navigation available, such as a map

or chart and a compass.

Also remember that this unit will always show navigation information in the

shortest line from your present position to a waypoint, regardless of terrain!

It only calculates position, it can’t know what’s between you and your des-

tination, for example. It’s up to you to safely navigate around obstacles, no

matter how you’re using this product.

How to use this manual: typographical conventions

Many instructions are listed as numbered steps. The keypad and arrow

"keystrokes" appear as boldface type. So, if you're in a real hurry (or just

need a reminder), you can skim the instructions and pick out what menu

command to use by finding the boldface command text. The following

paragraphs explain how to interpret the text formatting for those com-

mands and other instructions:

Arrow Keys

The arrow keys control the movement of dotted cross-hair lines on your

mapping screen called the cursor. The arrow keys also help you move

around the Atlas menus so you can execute different commands. They are

represented by symbols like these, which denote the down arrow key, the

up arrow, the left arrow and the right arrow: ↓ ↑ ← →.

Keyboard

The other keys perform a variety of functions. When the text refers to a key

to press, the key is shown in bold, sans serif type. For example, the "En-

ter/Save" key is shown as

ENT and the "Menu" key is shown as MENU.

Menu Commands

A menu command or a menu option will appear in small capital letters, in a

bold sans serif type like this:

ADVANCED MODE. These indicate that you are to

select this command or option from a menu or take an action of some kind
