Introduction Welcome to the Magellan GPS 310 Congratulations on your purchase of the Magellan GPS 310 satellite navigator. 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.
Magellan GPS 310 Key Functions GPS Antenna G P S 310 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. ENTER NAV MARK The MARK key is used to create landmarks and store the current position. The LIGHT key turns the light on and off. 2 GOTO MENU The MENU key is used to access the route, landmark and setup functions.
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.
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.
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.
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.
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 MARK . 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 To quickly save a position fix, press MARK MARK .
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.
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 Latitude and Longitude Satellite Elevation Degrees above the horizon of the satellite indicated by the satellite pointer. NAV key. North Indicator Satellite Pointer Number of satellites being used. Satellite Icons Visible but not tracked. Satellite is being tracked.
Viewing the Navigation Screens Without an Active Route. Without an active route the navigation screen displays your heading and the speed at which you are traveling. The lower portion of the screen displays a moving compass. The triangle at the top of the compass points in the direction you are traveling and the arrow points to north.
With an Active Route. When you have an active route the navigation screen still displays your heading and speed but also includes the bearing and distance to your destination. The moving compass is then replaced with steering information. You can use the graphical representation or the steering indicator to assist in directing you towards your final destination.
A second navigational screen is also provided while you have an active route. This screen is very similar to the first screen except that the distance to the destination has been replaced with XTE (cross track error, the distance left or right that you are off course) and heading has been replaced with TTG (time to go). This screen provides you additional information to aid you in navigating to your destination.
Creating a GOTO Route The simplest form of a route is a one-leg route called a GOTO route (you are GOing TO a destination). This is routing you from your current position to a landmark stored in memory All that is required to create a GOTO route is that you have saved a landmark indicating the location of your destination. To create (activate) a GOTO Route: From any screen, press GOTO screen appears. GOTO .
If the receiver is not tracking sufficient satellites to compute a position fix, the start of the newly created GOTO route will be the last position computed, which may not be the current position. This GOTO route will remain the active route until a new GOTO route is created, a multileg route is activated, or the receiver is turned off. Turning off the receiver deactivates any GOTO route. Summary This completes the basic operation of the GPS 310.
Working with Landmarks Viewing a Landmark To view a stored landmark press MENU until LMKS appears at the top of the screen. Press ENTER . The BEARING/DIS- TANCE screen for the first landmark in the receiver’s memory is displayed with the bearing and distance from the last computed position fix to that landmark. To select a different landmark, use the LEFT/RIGHT arrows until the name of the landmark you wish to view is at the top of the screen.
Editing a Landmark Following the instructions under Viewing a Landmark, use the LEFT/RIGHT arrows to select the landmark you wish to edit. Press the UP ARROW until the screen displays PRESS ENT TO EDIT, then press ENTER . You can modify the landmark name and/or the coordinates for the landmark by using the UP/DOWN arrows to change the information and press ENTER to move to the next line.
Working with Routes The route function allows you to link a series of landmarks and travel, point by point, to a final destination. D Leg 1 g C Leg 2 Le A 3 B The route depicted here is a three-leg route. Leg 1 extends from landmark A to landmark B, leg 2 from landmark B to landmark C, and leg 3 from C to D. The GPS 310 gives you information on the NAV screens that directs you to the destination of each leg sequentially.
The receiver prompts you for a starting landmark for the route. The first landmark, *POS, is your present position. Use the ARROW pad to scroll through the list of landmarks. When the desired landmark is displayed (and flashing) press ENTER . The display changes to allow the selection of the landmark to be used as the end of the first leg in the route. Use the ARROW pad to scroll through the list of landmarks. When the desired landmark is displayed (and flashing) press ENTER .
pad to select a landmark as the destination for this leg or press ENTER to signal the GPS 310 that this was the last leg in the route and you are finished creating a route. Continue this process for each leg in the route remembering to press ENTER with END ROUTE displayed in the TO field to finish up the route. If you accidently pressed the ARROW pad but you meant to end the route, you can still end the route by continuing to press the ARROW pad until END ROUTE is displayed again.
The first screen displayed is the ROUTE SUMMARY screen. This screen displays the start and end landmark for the entire route as well as the total distance of the route. Use the LEFT/RIGHT ARROWs to view the legs in the route. The leg screen displays the FROM and TO landmark for the leg as well as the distance and bearing for the leg. The circle graphically displays the bearing for the leg.
Deleting a Route With a route in memory, press MENU until ROUTE appears at the top of the display. Press ENTER . While still viewing the Route Summary screen, press the UP ARROW three times until the display indicates PRESS ENT TO DELETE. Press ENTER . You will be prompted to confirm the deletion. Use the ARROWs to select YES or NO and press ENTER . Adding Legs to a Route With a route in memory, press MENU until ROUTE appears at the top of the display. Press ENTER .
Activating a Leg in a Route As you are navigating you may decide that you no longer wish to continue on the leg that you are now using. Instead you wish to use another leg of the route. You will need to activate the leg of the route with the desired destination (TO landmark). Press MENU until ROUTE appears at the top of the display. Press ENTER . Use the LEFT/RIGHT ARROWs until the leg you wish to activate is displayed. Press the UP ARROW.
Editing a Leg in a Route Press MENU until ROUTE appears at the top of the display. Press ENTER . Use the LEFT/RIGHT ARROWs until the leg you wish to edit is displayed. Press the UP ARROW until PRESS ENT TO EDIT is displayed and press ENTER . The Edit Leg screen is displayed with the FROM landmark flashing. Use the LEFT/RIGHT ARROWs to select a new FROM landmark and press ENTER . The TO landmark begins flashing alerting you that the GPS 310 is ready for you to select a new TO landmark.
Deleting a Leg From a Route Press MENU until ROUTE appears at the top of the display. Press ENTER . Use the LEFT/RIGHT ARROWs to find the leg of the route that you want to delete. Press the UP ARROW until PRESS ENT TO DELETE is displayed and press ENTER . The GPS 310 prompts you to confirm the deletion of the leg. Use the LEFT/RIGHT ARROW to select (flashing) YES to delete or NO to cancel. If you attempt to delete a leg that causes the route to contain a leg that is under the 0.

Using the Trip Odometer Press MENU until the ODOMETER is displayed. The odometer will keep track of the distance you have traveled while using your GPS 310.
Connecting to External Devices The GPS 310 is designed to interface to a PC or other devices using a data cable. The GPS 310 continuously outputs NMEA messages through the data port at a rate of every 1 second. The GSV message is output all the time including when the receiver is not computing fixes. After the first fix is computed, GSA, GLL, GGA and RMC messages are also output. These messages contain position, time, date, satellite position as well as other status information.
Connecting the GPS 310 to an Autopilot Device To connect the GPS 310 to an autopilot or other external device you may need to cut off the DB9 connector and “hard wire” the cable to the device. The cable configuration is as follows: Orange: Data Out Yellow: Data In Black: Ground Red: Power (DO NOT USE) Refer to the manual on the external device and connect the wires to their proper place.
NMEA Data Messages NMEA DATA MESSAGES. NMEA data is output at 4800 baud, 8, N, 1, checksum off. These settings are acceptable to most equipment and software applications. Your GPS receiver outputs the following NMEA 0183 version 2.1 messages. GSA, GSV, GLL, GGA, RMB, RMC and APB. Vers. 2.1 NMEA is recommended for navigation data, satellite data and autopilots.

Troubleshooting Does not turn on: 1. Check to insure that the batteries are installed correctly and that the battery terminals are clean. 2. Replace the batteries. Takes more than 10 minutes to get a position fix: 1. If there are large obstacles nearby or overhead, move to a new location with a clear view of the sky and turn the receiver back on. 2. Make sure that the antenna is pointing up and that it is a reasonable distance from your body. 3. Check that the time is correct.
navigation information (destination pointer, etc.) is not updated until you are moving. (The receiver is unable to detect which way you are facing while you are stationary.) Position coordinates on your receiver do not match the location on your map. 1. Make sure that your receiver is set up to use the same datum as your map. The map datum is generally shown in the map legend. See Map Datum under Setup for instructions on selecting the map datum in your receiver. 2. Check your LAT/LON format.
Why won’t the receiver accept the coordinates higher than 59 seconds when I am inputting coordinates? The most common cause of this is you are trying to enter coordinates that are in degrees/minutes while your receiver is set to degrees/minutes/seconds. Since the last two digits in degrees/minutes is in hundredths (00 - 99) and degrees/ minutes/seconds can be no higher than 59 (00 - 59), inputting a number higher than 59 while in deg/min/sec results in an error and the receiver does not accept the entry.
Icons T R A C K I N G Provides a visual indication of whether the receiver is “locked” or “unlocked” on satellite signals. While the tracking icon is displayed, the receiver is updating its position and can be used to save landmarks and as a navigation tool. If the tracking icon is not displayed, you may need to reposition the GPS receiver to get a better view of the sky. Battery Warning. When this icon first appears, the receiver will operate for about an additional hour before automatically turning off.

Also, prior to shipping, you should loosen the battery door screw if you feel that your GPS 310 may be placed in an unpressurized area of an aircraft. Loosening the battery door will allow the GPS 310 to equalize to the pressure of the cargo area.
Glossary Active Leg The segment of a route currently being used to compute navigational information. Bearing The compass direction from your position to a destination, measured to the nearest degree. Coordinates A unique numeric or alphanumeric description of position. Datum Refers to the theoretical mathematical model of the earth’s sea level surface. Map makers may use a different model from which to chart their maps, so position coordinates will differ from one datum to another.
Landmark A location saved in the unit’s memory which is obtained by entering data, editing data, calculating data or saving a current position. Used to create routes. Latitude The angular distance north or south of the equator measured by lines encircling the earth parallel to the equator in degrees from 0° to 90°. LAT/LON Coordinate system using latitude and longitude coordinates to define a position on the earth.
TTG Time To Go (TTG) is the measurement of how long it will take you to arrive at your destination. TTG is based on how fast you are moving towards the destination and the distance remaining. True North The direction to the geographical North Pole from an observer’s position. The north direction on any geographical meridian. UT Universal Time, formerly referred to as Greenwich Mean Time (GMT).
