Getting Started This section shows you how to use your receiver for the first time and explains: • Accuracy • Battery Installation • Primary Usage • Getting a Fixed Position Receiver Accuracy The satellite constellation that provides the GPS information used by the receiver is maintained by the Department of Defense (DoD). GPS positioning, for general use, provides 25 meter RMS accuracy or better. Since the signals generated by these satellites are publicly accessible, the DoD has introduced errors in the satellite signals for security reasons. These errors are referred to as Selective Availability (SA). At present, your GPS position will be accurate within 100 meters horizontally and 150 meters vertically. Due to these errors introduced by SA, it is possible to get readings outside of these values at times. Installing the Batteries The receiver uses two AA batteries that are installed at the back. To remove the battery cover, turn the ring of the battery door screw counter-clockwise until the battery cover can be removed. Insert the new batteries as shown, being sure to respect the polarities, and replace the cover. - + + - Replace the screw and turn the ring clockwise until the battery door is held in place securely. Avoid overtightening the battery door screw. Once the batteries have been removed, the receiver loses time and date after 20 minutes. Magellan GPS 315/GPS 320 3
