CAUTION The GPS system is operated by the government of the United States which is solely responsible for its accuracy and maintenance. The system is under development and is subject to changes which could affect the accuracy and performance of all GPS equipment. Although the GPS 50 is a precision electronic NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted, and therefore become unsafe. Use the GPS 50 at your own risk. To reduce the risk, carefully review and understand al

Pressing the MSG/SET key allows you to view new messages when the "MSG" banner is flashing. (See Section 2.6 and Appendix A.) Pressing the MSG/SET key also selects the Setup Pages which allow you to view satellite tracking status and customize the unit as you like. (See Section 3.2 and Chapter 4.) Pressing the GOTO/MOB key once allows you to initiate the GOTO function, which will set an instantaneous course to any waypoint. (See Section 3.8.) Pressing the GOTO/MOB key twice in succession al

The Satellite Status Page may be displayed by pressing the SET key. This page shows the number of satellites tracked and visible, dilution of precision (DOP), and estimated position error (EPE). DOP is a measure of the satellite geometry quality and hence the relative accuracy of your position (1 meaning the best and 10 meaning poor). EPE, which is computed using the satellite geometry (DOP), signal, and data quality, receiver tracking status and other factors, is an overall measure of your p
