Introduction

Welcome to the Magellan GPS Blazer12
Congratulations on your purchase of the Magellan GPS Blazer12 satellite navigator. The GPS Blazer12 is an easy-touse GPS receiver designed to get you out in the Great Outdoors rather than spending hours reading a Users 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 Blazer12 box. If any items are missing or damaged, contact your Magellan dealer or retailer.

GPS Blazer12 Description

The GPS Blazer12 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 Blazer12 will operate for up to 20 hours.

to accept the current latitude and press again to accept the current longitude.
Shortcut: Press MARK at anytime while viewing this screen to quickly save the position.

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 GPS Blazer12 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.
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 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.

North Indicator

Tracking Indicator Appears when enough satellites have provided information to compute position fixes.
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.
Navigation Screen with an Active Route (Steering)
Destination Landmark Bearing to Destination Current Heading Destination Icon Distance to Destination Current Speed North Indicator Steering Indicator Indicates the number of degrees to turn, right or left, to destination landmark.
Destination Pointer Tracking Indicator Appears when enough satellites have provided information to compute position fixes.
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.
Second Navigation Screen with an Active Route (Steering)
Destination Landmark Bearing to Destination Time to Go Time remaining to arrive at the destination at your present speed and heading Destination Icon Destination Pointer Cross Track Error Distance left or right of the desired Courseline. Current Speed North Indicator Steering Indicator Indicates the number of degrees to turn, right or left, to destination landmark.

The navigation screens and the position screen are connected to one another in a circular loop. Pressing the NAV key or using the ARROW pad while viewing one of the position or navigation screens moves you to the next screen in the loop.

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.
To select a different landmark, use the LEFT/RIGHT ARROWS until the desired destination landmark is displayed.
Press ENTER or GOTO. The display returns to the Navigation screen showing the name of the GOTO destination at the top of the screen.
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 Blazer12. At this time it would be a good idea to put what you know to practice. Pick a location that you would want to come back to, your home for example. Take a position fix of the location and save it to memory, giving it a name that you will later associate with this location. Then travel a few miles away with your receiver, stop and take another position fix. Now use the GOTO key to set a GOTO route and highlight the landmark you created before and press ENTER. Your GPS Blazer12 is ready to navigate you back to where you started. The navigation screens are now showing you the distance and bearing back to the original landmark. As you begin moving, the GPS Blazer12 will begin using your speed and direction to compute the shortest distance back to your original starting point as well as how long it will take you to get there. The following chapters provide you with more information on using your GPS Blazer12 that build upon what youve learned.

Working with Landmarks

Viewing a Landmark
To view a stored landmark press
until LMKS appears at the top of the screen.
Press ENTER. The BEARING/DISTANCE screen for the first landmark in the receivers 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. To view the POSITION screen of the selected landmark, press the UP ARROW.

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. If the landmark you are editing is used in a route, the route will be modified to reflect the changes you made to the landmark.

Deleting a Landmark

Following the instructions under Viewing a Landmark, use the LEFT/RIGHT arrows to select the landmark you wish to delete. Press the UP ARROW until the screen displays PRESS ENT TO DELETE, then press ENTER. Use the LEFT/RIGHT ARROWs to confirm (YES or NO) and press ENTER. If the landmark is used in a route or is the destination landmark in a GOTO route, the GPS Blazer12 alerts you that the landmark cannot be deleted. Remove the landmark from the route and repeat.

Working with Routes

The route function allows you to link a series of landmarks and travel, point by point, to a final destination.

Le g 3

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 Blazer12 gives you information on the NAV screens that directs you to the destination of each leg sequentially.

Creating a Route

A route can contain up to 10 legs using any of the landmarks stored in memory. If there is a route already in memory you must delete the existing route before you can create a new one. Access the Route Menu by pressing

until ROUTE

appears at the top of the screen. The display should say PRESS ENT TO CREATE. NOTE: If the display says PRESS ENT TO VIEW there is an existing route and you must delete the existing route before creating a new one. (See Deleting a Route for details.) Press
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. Note that as you scroll through the list of landmarks, the display updates showing you the bearing and distance from the start of this leg to the displayed landmark. If the distance from the start of the leg to the end of the leg is below 0.10 miles, the message INVALID is displayed and you are prompted to select a different landmark. The screen changes to the next leg in the route with the destination landmark of the previous leg inserted as the start of the next leg. The message END ROUTE is displayed in the TO field. You may continue this route by using the ARROW
pad to select a landmark as the destination for this leg or press ENTER to signal the GPS Blazer12 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. A route may contain no more than ten legs and the GPS Blazer12 automatically saves the route and returns to the Route Menu as soon as Leg 10 is entered. After the route has been created, the GPS Blazer12 automatically activates the route and begins providing navigation information for the route.

Viewing a Route

You can view a summary of the route in memory as well as viewing the individual legs of the route. All editing commands are accessed from the View Route function as well. With a route in memory, press at the top of the display. Press

MENU ENTER

until ROUTE appears.
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. Continue pressing the LEFT/RIGHT ARROWs to step through the other legs in the route, eventually returning to the ROUTE SUMMARY screen.

Commonly Asked Questions

Does the receiver adjust itself for daylight savings time? No. You need to reset the time for changes in your area. (See Changing Time Display and Time on page 28.) Will my receiver function correctly in the year 2000? Absolutely. Even though only the last two digits of the year are displayed, the full year designator is stored in memory.
Why wont 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. Can I use NiCad Batteries in my GPS Blazer12? Yes. However, the battery life of your GPS Blazer12 will be diminished with the use of NiCad batteries. Can I attach my GPS Blazer12 to external power? Yes. However, this requires the optional external power cable available from your dealer or Magellan Systems. Will I lose all my landmarks when my batteries die? No. As long as you leave the batteries inside the GPS Blazer12, memory will be retained for up to one month, even with dead batteries. (With good batteries installed, you can store your GPS Blazer12 for six months without losing any memory.) When you remove batteries, you have 30 minutes to install new batteries before memory is lost. Why does my speed and elevation sometimes jump around? For security reasons, the U.S. Government introduces small errors (selective availability) which can affect positioning information. These errors are most noticeable while viewing speed, heading, and elevation.
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. The Magellan GPS Blazer12 will retain its memory (route, landmarks, last fixes, etc.) for 30 minutes with the batteries removed. Memory will be retained even with low batteries for approximately one month if the unit is turned off. Light. Displayed when the LCD backlight has been turned key. The backlight will cause the batteries to on with the run down much quicker and should be turned off when not needed. External Power. Displayed when the GPS Blazer12 is operating from external power using the GPS External Power Cable.

Shipping / Transporting

If you ship or transport your GPS Blazer12 more than 100 miles, you may need to reinitialize the GPS Blazer12 again at your new location. This will speed up the time it takes to get your first fix after shipment. Also, prior to shipping, you should loosen the battery door screw if you feel that your GPS Blazer12 may be placed in an unpressurized area of an aircraft. Loosening the battery door will allow the GPS Blazer12 to equalize to the pressure of the cargo area. Changes in pressure without the battery door loosened can cause damage to the water seals of your receiver.

Glossary

Active Leg Bearing The segment of a route currently being used to compute navigational information. The compass direction from your position to a destination, measured to the nearest degree. A unique numeric or alphanumeric description of position. Refers to the theoretical mathematical model of the earths 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. The datum for the map you are using can be found in the legend of the map. If you are unsure as to which datum to use, use WGS84. Distance above mean sea level. A single leg route with the present position being the start of the route and a defined landmark as the destination. (If the unit has been moved while turned off and has not yet acquired a new position fix, the start of the GOTO will be the position fix last recorded.) The compass direction in which the Magellan GPS Blazer12 is moving.

Coordinates Datum

Elevation GOTO

Heading

Landmark
A location saved in the units memory which is obtained by entering data, editing data, calculating data or saving a current position. Used to create routes. 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. Coordinate system using latitude and longitude coordinates to define a position on the earth. A segment of a route that has a starting (FROM) landmark and a destination (TO) landmark. A route may consist of 1 or more legs. A route that is from landmark A to landmark B to landmark C to landmark D has three legs with the first being from landmark A to landmark B. The angular distance east or west of the prime meridian (Greenwich meridian) as measured by lines perpendicular to the parallels and converging at the poles from 0 to 180.
