The GPS 310 is an easy-to-use GPS receiver designed to get you out in the "Great Outdoors" rather than spending hours reading a User's Manual. There are, however, a few items that you need to be familiar with so it is suggested that you follow along at least through the chapter on Basic Operation. Before you begin, make sure that your package includes the items listed on the GPS 310 box. If any items are missing or damaged, contact your Magellan dealer or retailer. GPS 310 Description The GPS 310 is a self-contained hand-held GPS receiver designed for general purpose position locating and navigation. It has a built-in antenna located at the top of the receiver, a backlit display, and keypad. Using two AA batteries, inserted from the battery door found at the back of the receiver, the GPS 310 will operate for up to 20 hours. 1 Magellan GPS 310 Key Functions GPS Antenna G P S 31 0 The ENTER key confirms data entries or menu selections. The NAV key accesses the Position and Navigation screens. The GOTO key is used to create a direct route to any landmark stored in memory. The MENU key is used to access the route, landmark and setup functions. The PWR key turns the receiver on and off. ENTER NAV GOTO MARK MENU The MARK key is used to create landmarks and store the current position. PWR The LIGHT key turns the light on and off. The ARROW pad is used to enter landmark names, and scroll through the series of screens and menu selections. 2 Getting Started Installing the Batteries The GPS 310 uses two AA alkaline batteries that are installed at the back of the receiver. To remove the battery cover, turn the ring of the battery door screw counterclockwise until the battery cover can be removed. Insert the new batteries as shown, being sure to respect the polarities, and replace the battery cover. + + - Replace the screw and turn the ring clockwise until the battery door is held in place securely. While the battery door does provide the waterproofing seal to the batteries, you should avoid overtightening the battery door screw. Getting Signals from Satellites Since the GPS 310 receives information from satellites orbiting the earth, the antenna needs to have a relatively unobstructed view of the sky. Large obstructions such as buildings, cliffs, and overhangs may interfere with signal reception causing your GPS 310 to take additional time to compute your location. 3 The GPS 310 is designed to fit comfortably in your hand. Hold the receiver with the antenna towards the sky. Initializing the Receiver - EZStart Before using your GPS 310 for the first time, the receiver needs to know its approximate location. Using Magellan's EZStart procedure, the GPS 310 will prompt you for the information it requires when you turn it on for the first time. You do not need to initialize your receiver each time you use it. Follow these steps to initialize the GPS 310 if this is the first time you are using it. Press PWR to turn the GPS 310 on. SELECT REGION. Use the ARROW pad to change the flashing text to select the appropriate region for your present location. Press ENTER SELECT COUNTRY or STATE. Use the ARROW pad to change the flashing text to select the country or state for your present location. Press ENTER 4 ENTER ELEVATION. Use the ARROW pad to enter the approximate elevation for your position. If unknown, leave the elevation at 0. Press ENTER ENTER TIME. Use the ARROW pad to enter your present time. Press ENTER ENTER DATE. Use the ARROW pad to enter the date. Press ENTER The GPS 310 then displays the POSITION screen and automatically begins searching for satellites that it knows are in this area for the date and time you entered. The display shown here may differ from yours depending upon the information you selected in steps 2 and 3. As the GPS 310 scans the sky, the arrow in the circle will swing around pointing to a satellite and displays, in the center of the circle, that satellite's elevation above the horizon. Computing a Position The GPS 310 will begin to acquire information from the satellites and use this information to compute your current position (called a position fix). Whether you have just 5 completed the initialization process or have just turned your GPS 310 on, the GPS 310 will display the following screens in the order shown. As the GPS 310 searches for satellites, some of the small circles around the large circle will become black indicating that the GPS 310 is tracking that satellite and receiving information. The number at the bottom right of the screen displays how many satellites are being tracked. After the GPS receiver has received positioning data from at least three satellites (approximately 2-3 minutes), it will begin computing a position fix based upon the information it is receiving. As soon as a position fix is computed, the receiver switches to the navigation screen displaying the moving compass. The word "TRACKING" is displayed in the lower right corner indicating that the receiver is computing position fixes. Note: If the receiver has not acquired a position fix in approximately 10 minutes, refer to the troubleshooting section of this manual. More information on these screens and the information they display can be found in the next chapter. 6 Basic Operation Saving a Position Fix Position fixes can be saved in memory for use later when you want to return to that position. Saved position fixes are referred to as landmarks or LMK. To save (mark) your current position press Receiver-Generated Name: The GPS 310 prompts you to enter a name or accept the receiver-generated name for this landmark. To accept the receiver-generated name (LM01 - LM99), press ENTER MARK . To quickly save a position fix, press MARK MARK . User-Created Name: To create a name (up to four characters), use the UP/DOWN arrows to change the character and the LEFT/RIGHT arrows to move the cursor to the left or right respectively. After you have input the desired landmark name press Press ENTER . ENTER to accept the current latitude and press ENTER again to accept the current longitude. MARK at Shortcut: Press anytime while viewing this screen to quickly save the position. 7 Creating a Landmark To create a landmark at a location which is not your current position, use the same procedure as saving a position with the additional step of inputting different latitude/longitude coordinates. To create a landmark press MARK . The GPS 310 prompts you to enter a name or accept the receivergenerated name for this landmark. When the desired name is displayed at the top of the screen press ENTER . Use the ARROW pad to change the latitude and press ENTER to accept. Use the ARROW pad to change the longitude and press ENTER to accept. The newly created landmark is stored in memory and you are returned to the screen that was displayed when you pressed the MARK key. Shortcut: Press MARK at anytime while viewing this screen to quickly save the position. 8 Viewing the POSITION Screen The POSITION screen displays the coordinates for your last computed position and information about any satellites that are visible. It can be accessed by pressing the NAV key. Latitude and Longitude North Indicator Satellite Pointer Number of satellites being used. Satellite Elevation Degrees above the horizon of the satellite indicated by the satellite pointer. Satellite Icons Visible but not tracked. Satellite is being tracked. Tracking Indicator Appears when the receiver has acquired enough information from the satellites to compute a position fix. You m ...
