There, however, are some fringe areas of the U.S., including parts of 

Alaska, that do not yet receive robust WAAS coverage. Continued WAAS 

development is planned to extend WAAS coverage in the years to come. 
WAAS boosts the accuracy of land GPS navigation, but the system is 

designed 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 America. Aircraft and vessels on open water can get consis-

tently good WAAS reception, but terrain, foliage or even large man-made 

structures can sometimes block the WAAS signal from ground receivers. 
You'll find that using your GPS receiver is both easy and amazingly 

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

available to the general public today. Remember 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 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 destination. It’s up to you to safely navigate around obstacles, 

no matter how you’re using this product. 

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 fol-

lowing paragraphs explain how to interpret text formatting for those 

commands and other instructions: 
Arrow Keys 

The arrow keys control the movement of dotted crosshairs lines (the 

cursor) on your mapping screen. The arrow keys also help you move 

around the iFINDER 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: 

↓ ↑ ← →. 

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 

"Enter/Save" key is shown as 

ENT 

and the "Menu" key is shown as 

. 

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

in a bold sans serif type like this:

are to select this command or option from a menu or take an action of
