WARNINGS

A measure of knowledge by the user is required for proper and safe use of the Magellan GPS 310™. READ THE USER MANUAL & WARRANTY COMPLETELY.

This product is an excellent navigation aid, but it does not replace the need for careful orientation and good judgment. Never rely solely on one device for navigating.

The Global Positioning System (GPS) is operated by the U.S. Government, which is solely responsible for the accuracy and the maintenance of GPS. Certain conditions can make the system less accurate.

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.

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.

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.

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

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.

ENTER

Press

 ENTER ELEVATION. Use the ARROW pad to enter

the approximate elevation for your position. If unknown,

leave the elevation at 0. Press

 ENTER TIME. Use the ARROW pad to enter your

present time. Press

ENTER

 ENTER DATE. Use the ARROW pad to enter the date.

ENTER

Press

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

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.

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

(LM01 - LM99), press

To quickly save a position fix, press

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

The newly created landmark is stored in memory and you are returned to the screen that was displayed when you pressed the MARK key.

are visible. It can be accessed by pressing the

Satellite Pointer

Number of satellites being used.

You may sometimes notice that the number of satellites being tracked differs from the number of satellites being displayed graphically. This is due to more than one satellite being tracked in the same general area.

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.

The navigation screens display your speed of travel. In order for the North Indicator to be valid and the speed to be displayed, you must be moving at a speed greater than 2 miles

per hour.

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.

In the screen above you are traveling with a heading of 56° while your destination bearing is 34°. This would indicate that you need to turn left 22° to be on a straight line to your

destination. The circle and arrow display the same information but in a visual manner. The triangle points in the direction you are traveling and the arrow points towards your 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.

key or

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

. The

GOTO screen appears.

To select a different landmark, use the LEFT/RIGHT ARROWS until the desired destination landmark is displayed.

ENTER

Press

GOTO

. The display

returns to the Navigation screen showing the name of the GOTO destination at the top of the screen.
