Receiver Status and EPEReceiver status is indicated at the top left of the screen,with the current horizontal accuracy (estimated positionerror, in feet or meters) at the top right. The status willshow one of the following conditions:Searching— the GPS 45XL is looking for any availablesatellites in view.AutoLocateTM— the GPS 45XL is initializing and col-lecting new almanac data. This process can take 7.5 to15 minutes.Acquiring— the receiver is collecting data from avail-able satellites, but has not collected enough data to cal-culate a 2D fix.2D Navigation— at least three satellites with goodgeometry have been locked onto and a 2-dimensionalposition fix (latitude and longitude) is being calculated.‘2D Diff’ will appear when you are receiving DGPS cor-rections in 2D mode.3D Navigation— at least four satellites with goodgeometry have been locked onto, and your position isnow being calculated in lat itude, longitude and altitude.‘3D Diff’ will appear when you are receiving DGPS cor -rections in 3D mode.Poor GPS Coverage— the receiver is no longer track-ing enough satellites for a 2D or 3D fix.Not Usable— the receiver is unusable, possibly due toincorrect initialization or abnormal satellite conditions.Turn the unit off and back on to reset.Simulating Navigation— the receiver is in simulatormode.EZinit Option PromptThe satellite status page also provides access to theEZinit prompt whenever a position fix has not been calcu-lated (the unit must be in searching, AutoLocate, acquiring,simulator or poor coverage mode). This allows you to man-ually reinitialize the unit (see page 5-8 for instructions),and is useful if you have travelled over 500 miles with thereceiver off and you know it must be initialized to yournew position (the GPS 45XL will automatically offer theEZinit prompt after 10 minutes of unsuccessful satelliteacquisition).18ReferenceSatelliteStatus PageA ‘Poor Coverage’ statuswill appear if the receiverhas lost the satellitesrequired to compute a fix.Make sure the internalantenna is not covered andhas a clear view of the sky.If you travel more than 500miles with the receiver off,you may have to reinitializeit to your new location. Toaccess the EZinit prompt,press ENTER from the statuspage before the receiver hasacquired any satellites.
