Since introducing the world's first commercial, hand-held GPS receiver in 1989, Magellan has led the way with innovative GPS products to meet a wide range of positioning and navigation needs. The receiver is designed to get you out into the "Great Outdoors" rather than spending hours reading the user's manual. In order to get you outdoors quickly, the manual is designed with key sequences rather than wordy sentences. Before you begin, make sure that your package includes the items listed on the box. If any of these items are missing, please contact your local Magellan dealer or distributor. Conventions Used in this Manual The manual is divided into chapters: Introduction, Getting Started, Basic Operation, Reference, Customizing, Troubleshooting and Glossary. There are also subchapters that describe NMEA, Datums and Accessories. It is very important that you read through the Getting Started chapter first as it prepares your receiver for use and provides basic instruction. The Basic Operation chapter describes the features found in your receiver including step-by-step instructions on their use. The Reference section contains information to help you navigate using waypoints, routes and auxiliary functions. Following is the Customizing chapter, that allows you to establish options you want set in the receiver. The Troubleshooting chapter gives you a problem and answer series to guide you. The final chapter, Glossary, defines terms that may be unfamiliar to you. The manual is to be used with either the GPS 315 or the GPS 320. These differ in that the GPS 315 has a database of worldwide cities consisting of major, large and medium cities. The GPS 320 has a database of worldwide cities as well as lighthouses, fixed navaids, buoys, large and medium cities for three different regions of the world (North/ Central/South America, Europe/Africa and Australia/Asia). Magellan GPS 315/GPS 320 1 GPS 315/320 Receiver Quadrifilar antenna The QUIT key cancels the operation of the last key press and can be used to back through the NAV screens. The ENTER key confirms data entries or menu selections. The NAV key accesses the navigation screens. The GOTO key creates a direct route to any waypoint stored in memory. The MARK key creates waypoints and stores the current position. The MENU accesses waypoint, route and setup functions. The LIGHT key turns the light on and off. The PWR key turns the receiver on and off. The ARROWs enter information and scroll through menus. 2 Magellan GPS 315/GPS 320 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 Proper Handling - Signal Reception Clear View of the Sky. Because the receiver attains information it needs from satellites orbiting the earth, the antenna needs to have a relatively unobstructed view of the sky. This allows the receiver to choose from all satellites currently available. If the view of the sky is poor, (large cliffs or buildings, heavy foliage or other obstructions) the satellite signals can be blocked and the receiver may take longer to compute a position fix. Holding the Receiver. The receiver is designed to fit comfortably in your hand. Hold the receiver in the palm of your hand with the antenna pointing towards the sky. Power On PWR If after powering the receiver on, you do not press ENTER within 10 seconds, the receiver will shut off automatically. Initialize You do not need to initialize your receiver each time you use it unless the memory has been cleared or if it has been transported more than 300 miles while turned off. Initialize for First Time Use If the Initialize screen does not appear, then the receiver has already been initialized. The other steps in this procedure are not required. PWR Select ENTER language Select area Enter time INITIALIZE screen ENTER Select region ENTER ENTER Enter * elevation Enter date ENTER ENTER ENTER * If you do not know your elevation, press 4 ENTER . Magellan GPS 315/GPS 320 Selecting Primary Usage A screen will be displayed asking your primary use for your receiver, MARINE or LAND. The default is MARINE. ENTER You have completed the Initialization. The STATUS screen will appear on your receiver. The following chart shows the terminology that your receiver uses while in land or marine mode. For purposes of this manual, it will be assumed that the receiver is in the marine mode.

The receiver will begin acquiring data from the satellites in view and will display the progress on the STATUS screen. Once the receiver has computed a fixed position, the POSITION screen will be displayed. Saving Your Waypoint Once the receiver has computed your current position, you may save (MARK) this position as a waypoint. Saving Your Position with a Receiver-Created Name. This is a fast way to save your position. MARK MARK Saving Your Position with a User-Created Name. MARK ENTER Enter data MARK You can save up to 500 waypoints in your receiver and refer back to them at any time. Creating a GOTO A GOTO is a route that guides you from your current position to any waypoint in the receiver's memory. Select category Select waypoint GOTO ENTER ENTER This completes the Getting Started section. The following Basic Operation section will familiarize you with the NAV screens and more detailed functions. 6 Magellan GPS 315/GPS 320 Basic Operation Entering Information Throughout this user manual there are some key presses that will be used often, so please keep them in mind while setting up and navigating.
