The GPS 310 will begin to acquire information from the satellites and use this information to compute your current position called a position fix Whether you have just completed the initialization process or have just turned your GPS 310 on the GPS 310 will display the following screens in the order shown As the GPS 310 searches for satellites some of the small circles around the J1 CEAR large circle will become black indicating ee ae that the GPS 310 is tracking that seems TN satellite and receiving information The yp fo number at the bottom right of the bao a screen displays how many satellites are I being tracked After the GPS receiver has received positioning data from at least three me Gees satellites approximately 2 3 minutes it 777 gt will begin computing a position fix gab gad based upon the information it is am ma receiving As soon as a position fix is oN computed the receiver switches to the ee navigation screen displaying the moving U m compass The word TRACKING is displayed in the lower right corner indicating that the receiver is computing position fixes Note If the receiver has not acquired a position fix in approximately 10 minutes refer to the troubleshooting section of this manual More information on these screens and the information they display can be found in the next chapter Basic Operation Saving a Position Fix2.
