46Initializing Your GPS 12CX for First-Time UseThe GPS 12CX typically acquires a position fastenough that initialization is not required. However, ini-tialization may be necessary for the following:• After memory loss• When the receiver has been moved more than 500miles with the power off.Additionally, it may be necessary to initialize theunit the first time you use it, if it does not acquire a fixafter the first few minutes.The receiver is shipped from the factory in AutoLo-cate™ mode, which enables the GPS 12CX to deter-mine its location anywhere in the world. To speed upthe initialization process, we recommend using thegraphic initialization described below, which will usu-ally provide a fix in a few minutes.To turn the GPS 12CX on:1. Press thePOWER key until the receiver turns on .The welcome page will be displayed while the unitconducts a self test. Once testing is complete, the wel-come page will be replaced by the Satellite Page, andthe EZinit prompt may appear prompting you to selectone of two initialization methods• Select Country – allows you to initialize the receiver byselecting your present position from a list of countriesin the GPS 12 CX’s internal database. This typicallyprovides a position fix in under three minutes.• AutolocateTM – allows the GPS 12CX to initialize itselfand calculate a position fix without knowing your presentposition. This usually provides a fix in 3-5 minutes.If the EZinit prompt has not automatically appearedon the Satellite Page:1.
