This screen shows a graphical view of the satellites that are in view. Each 

satellite is shown on the circular chart relative to your position. The point in 

the center of the chart is directly overhead. The small inner ring represents 

45° above the horizon and the large ring represents the horizon. North is at 

the top of the screen. You can use this to see which satellites are obstructed 

by obstacles in your immediate area if the unit is facing north. 
The GPS receiver is tracking satellites that are in bold type. The re-

ceiver hasn't locked onto a satellite if the number is grayed out, there-

fore it isn't being used to solve the position. 
Beneath the circular graph are the bar graphs, one for each satellite in 

view. Since the unit has twelve channels, it can dedicate one channel 

per visible satellite. The taller the bar on the graph, the better the unit 

is receiving the signals from the satellite. 
The "Estimated Position Error" (horizontal position error) shown in the 

upper left corner of the screen is the expected error from a benchmark 

location. In other words, if the EPE shows 50 feet, then the position 

shown by the unit is estimated to be within 50 feet of the actual loca-

tion. This also gives you an indicator of the fix quality the unit cur-

rently has. The smaller the position error number, the better (and more 

accurate) the fix is. If the position error flashes dashes, then the unit 

hasn't locked onto the satellites, and the number shown isn't valid. 
The Satellite Status Page has its own menu, which is used for setting 

various options (Options and setup are discussed in Sec. 5.). To access 

the Satellite Status Page Menu, from the Status Page, press

This screen has a compass rose that not only shows your direction of 

travel, but also the direction to a recalled waypoint. To get to the Navi-

gation Page: Press
