Initializing Your GPS 48 for First-Time UseThe GPS 48 does not require initialization undernormal day-to-day use. However, initialization mayreduce the time it takes to compute a position fix afterone of the following events:• After memory loss• When the receiver has been moved more than500 miles with the power off.Additionally, it may be necessary to initialize theunit the first time you use it, if it does not acquire a fixin a few minutes.The receiver is shipped from the factory inAutoLocate™ mode, which enables the GPS 48 todetermine its location anywhere in the world. Anothermethod is the graphic initialization described below,which usually provides a fix in a few minutes.To turn the GPS 48 on:1. Press and hold B until the receiver turns on.The welcome page is displayed while the unit con-ducts a self test, followed by a warning page.Once testing is complete, the warning page isreplaced by the Satellite Page, with the EZinit promptready for you to select one of two initializationmethods:•Select Country––allows you to initialize thereceiver by selecting your present position from alist of countries in the GPS 48’s internal database.This method usually provides a position fix in afew minutes.•AutolocateTM ––allows the GPS 48 to initializeitself and calculate a position fix without knowingyour present position. This usually provides a posi-tion fix in 3-5 minutes.The EZinit prompt can be activated from the satel-lite page by pressing the E key if the unit has notacquired satellites.Note: If the EZinit prompt appears after you haveinitialized the receiver (due to the antenna’s view ofsatellites being obstructed), highlight the ‘NO RE-INIT’selection with the arrow keypad and press E.Initializing theReceiverGETTINGSTARTED6Hold the receiver parallel tothe ground and rotate theantenna perpendicular tothe receiver.Welcome Page
