Garmin GPS 12XL Owner's Manual (Software Version 2.00-3.62) - Page 17

Receiver Status Receiver status is indicated at the top left of the page, with the current horizontal accuracy (estimated position error, in feet or meters) at the top right. The status will be shown as one of the following conditions: Searching- the GPS 12XL is looking for any available satellites in view. AutoLocate- the GPS 12XL is initializing and collecting new almanac data. This process can take 5 minutes, depending on the satellites currently in view. Acquiring- the receiver is collecting data from available satellites, but has not collected enough data to calculate a 2D fix. 2D Nav (2D Navigation)- at least three satellites with good geometry have been locked onto and a 2-dimensional position fix (latitude and longitude) is being calculated. '2D Diff' will appear when you are receiving DGPS corrections in 2D mode. 3D Nav (3D Navigation)- at least four satellites with good geometry have been locked onto, and your position is now being calculated in latitude, longitude and altitude. '3D Diff' will appear when you are receiving DGPS corrections in 3D mode. Poor Cvg (Poor GPS Coverage)- the receiver isn't tracking enough satellites for a 2D or 3D fix due to bad satellite geometry. Not Usable- the receiver is unusable, possibly due to incorrect initialization or abnormal satellite conditions. Turn the unit off and back on to reset, and reinitialize the receiver if necessary. Simulator- the receiver is in simulator mode. EZinit Option Prompt The Satellite Page also provides access to the EZinit prompt whenever a position fix has not been calculated. (The unit must be in searching, AutoLocate, acquiring, simulator, or poor coverage mode.) This allows you to reinitialize the unit (see Appendix A), and is useful if you have traveled over 500 miles with the receiver off and must initialize your new position. (The EZinit prompt will automatically appear if the receiver needs to be initialized. The prompt may also appear during normal use if the antenna is shaded or the unit is indoors. REFERENCE Receiver Status & EZinit The signal strength bars at the bottom of the page will not appear until the GPS 12XL has found the satellites indicated at the bottom of the screen. If you travel more than 500 miles with the receiver off, reinitialize the unit to your new position by using the EZinit feature. To access EZinit, press ENTER from the Satellite Page before any satellites are acquired. 13
