GETTING STARTED Satellite Status Page The signal strength bars give you an indication of what satellites are visible to the receiver, whether or not they're being used to calculate a position fix, and the signal quality. Let's start with the Satellite Status Page, which is the page you'll view while your unit is getting a position fix. If you're not already on this page, press PAGE or QUIT until it appears. The Satellite Status Page shows you status information that helps you understand what the receiver is doing at any given time, and it's a page that you'll want to occasionally refer back to as you use your unit. It features a sky view of available satellites, corresponding signal strength bars, the status of your current position fix (acquiring, 2D, 3D, etc.), and your estimated position error (EPE). You can also tell how much battery power is remaining, and you can adjust the screen contrast/backlighting by pressing the rocker keypad. Satellites are indicated on the sky view and the signal strength bars by their corresponding number, from 01 through 32. The sky view shows where it is looking in the sky for each satellite, by indicating the direction and elevation (angle above the horizon). The signal strength bars depict the relative strength of the signal from each satellite being received. The taller the bar, the stronger the signal. Receiver Status Signal Strength Bar If satellite reception is lost, or an insufficient number of satellites are available, you will be alerted with a 'Poor Coverage' receiver status and message. 8 Battery Level Indicator Satellite Status Page Sky View
