INTRODUCTION
Welcometo the excitingworld of GPS!Whether you’rea first-time user or
a professional navigator, you’ll find the Map Guide Pro is a full-featured
GPS receiver at a price that was impossible just a few years ago. The
Rockwell®receiver built inside has 12 channels that will track all of the
satellitesthat are inviewof yourlocation.It’sacquisitiontime and tracking
ability are second to none in its class.
TheGlobalPositioningSystem(GPS)wasdevelopedbytheUnitedStates
Department of Defense as a 24-hour a day, 365 days a year global navi-
gationsystem forthemilitary.Civilianavailability was added (butwith less
accuracy)using the same satellites.Twenty-foursatellitesorbit the Earth.
Three of these satellites are spares, unused until needed.The rest virtu-
allyguaranteethat at least foursatellites are in viewof anyplace on Earth
at all times.
The system requires three satellites in order to determine a position.This
is called a 2D fix. It takes four satellites to determine both position and
elevation, (your height above sea level - also called altitude.) called a 3D
fix.
Remember, the unit must have a clear view of the satellites in order to
receive their signals. Unlike radio or television, GPS works at very high
frequencies.The signals can be blocked easily by trees, buildings, even
your body. Fortunately, they do travel through glass and plastic, so your
receiver will work in the car, if it has a clear view of the satellites through
the windshield or side windows.Let someone else drive if you use it in a
car or other vehicle.
Never use this GPS receiver while operating a vehicle!
The first time you use this unit, walk outside and turn it on in your back-
yard, an open field or park. Once it locks onto the satellites, you can ex-
periment with it around buildings and trees.This will give you some idea
of its sensitivity to blockage.
Like most GPS receivers, this unit doesn’t have a compass or any other
navigation aid built inside.It relies solely on the signals from the satellites
to calculate a position. Speed, direction of travel, and distance are all
calculatedfromposition information.Therefore,inorderforittodetermine
direction of travel, you must be moving and the faster, the better.This is
not to say that it won’t work at walking speeds - it will.There will simply be
more “wandering” of the data shown on the display.

2
S/A -What is it?
Another factor that greatly influences the receiver’s ability to determine
position is SA.The United States government intentionally degrades the
satellites signal for civilian users.They introduce small errors into the sig-
nals that makes the GPS receiver less accurate.These errors are called
selective availability, or SA.How bad is it?They guarantee that the posi-
tion reported by a GPS receiver that meets their specifications is within
100 meters horizontally and 150 meters vertically 95% of the time. (The
position can be better than that or worse than that the other 5% of the
time.) In other words, the position shown on your receiver is within 100
meters of your actual position, 95% of the time.That’s over 300 feet! Not
exactly pinpoint accuracy, but then few people need positioning accuracy
greater than this.However, if you do want better performance, (and who
doesn’t?) many manufacturers (including Eagle) sell a DGPS receiver
that attaches to your GPS receiver.The DGPS system transmits correc-
tionsignals that nullifytheeffectsofSA.The DGPS receivertakessignals
from these land-based transmitters and gives them to the GPS receiver
whichthen uses themto showamore accurate position.The ironicpart is
thefederalgovernmentimplementedSAandisalsooperatingmanyDGPS
transmitters.(You can use the signals from all of the Coast Guard DGPS
stations for free, by the way.) The downside to this is it requires another
piece of electronic gear (the DGPS receiver) which usually isn’t small
enough to carry with you, but will work nicely on a vehicle.And you have
to be close enough to a station to receive the DGPS signals.
Don’t Get Lost
Generally, you find that using your GPS receiver without DGPS is both
easy and amazingly accurate. It’s easily the most accurate method of
electronic navigation available to the general public today. Remember,
however, that this receiver is only a tool.Always have another method of
navigation available, such as a chart or map and a compass.It’s a good
idea to carry spare batteries with you, especially if you’re venturing into
unknown territory.
Also remember that this unit will always show navigation information in
the shortest line from your present position to a waypoint, regardless of
terrain! It only calculates position, it can’t know what’s between you and
yourcamp,forexample.It’s upto youtosafelynavigatearoundobstacles,
no matter how you’re using this product.

GETTING STARTED
Power
The Map Guide Pro operates from AA batteries, a DURACELL®NiMH
rechargeable battery, or from 5 to 35 volts DC using the external power
cable.Ifthepowercable isused,theMapGuideProautomaticallyswitches
to it if the external power is greater than the battery voltage. If for any
reason the external power fails, the unit automatically switches to the
batteries.
BATTERIES
The unit requires four AA batteries.We recommend you use alkaline bat-
teries for the best trade-off between battery life and cost. However, you
can use nickel-cadmium (ni-cad), or lithium batteries.You can also use
rechargeable alkaline batteries such as RayOVac®Renewals®.With the
exception of lithium, none of the above batteries will last as long as stan-
dard alkaline batteries. We recommend DURACELL®brand, but others
will work.Do not use“heavy-duty”batter-
ies or any type other than the ones listed
above. Do not mix different types of bat-
teries.(For example, don’t use both alka-
lineandni-cadbatteriesat thesametime.)
Battery Installation
First turn the unit so that its back is facing
you.Push the two tabs to the left and re-
move the battery cover as shown at right.
Install the batteries according to this dia-
gram.(There’s adecalin the batterycom-
partment showing the correct polarity,
also.) Replace the battery compartment
cover and the unit is ready for use.
NiMH Battery
The DURACELL®DR-121 nickel-metal hydride (NiMH) battery replaces
thefourstandardbatteries.It issold as an accessory,(modelBR-1) which
includes a charger custom designed for the DR-121.The battery never
needs to be removed from the unit, since the charger connects to the
GPS receiver and charges the DR-121.You can even use the receiver
while the battery is charging!
To install the NiMH battery, remove the battery cover and place the bat-
tery into the compartment as shown on the next page. It will only fit one
way, so if it’s difficult to install, simply turn it over and drop it into place.
Replace the compartment cover and follow the charging instructions in-
cluded with the BR-1.

(Note: The DR-121 is the only battery that
can be recharged in this unit! Using the ex-
ternal powercablealonedoesnotchargethe
battery!You must use a charger supplied by
Eagleinordertochargethe battery.Also, this
charger will only charge a DR-121. It will not
chargeanyothertypeofbattery, includingni-
cads or rechargeable alkallines.)

There are 12 keys on the keyboard. You navigate through the menus,
adjust the chart’s cursor, and enter data
using the arrow keys.The five major modes

a feature from a list. The Z-IN and Z-OUT
keys zoom-in or zoom-out the view on the
plotter screen.The ENT and EXIT keys are
usedtoenteror clear data or screens. Save
and edit waypoints using the WPT key.The

it once while the unit is operating turns on
the screen’s backlight. To prevent an acci-
dental shutdown, you must hold the PWR key down for a few seconds in
order to turn the unit off.
Menus
Most of the unit’s features are found on “menus’.You can view the menus
by pressing the MENU key.This product has “Intelligent Menus”. There
are many menus that pertain to only the map, for example. When you
pressthe MENU keyandthe plotter is showing,menuitemsfortheplotter
showinadditiontothe normalmenus.Forexample,ifthenavigationscreen
is showing, and you press the MENU key, plotter menu items won’t show
on the list.This helps you find the needed item without scrolling through

5
unnecessary menus.
Turning Power On
To turn the unit on, simply press the PWR key. A GPS
logoscreenappears,thenthescreensimilartotheone
at right appears. Read the message on the screen,
then press the EXIT key to erase it or wait a few sec-
onds and it automatically clears. The screen shown
below appears next.
Satellite Status Screen
This screen appears each time you turn the unit on.It shows a graphical
view of the satellites that are in view.Each satellite is shown on the circu-
lar chart relative to your position. The point in the center of the chart is
directly overhead.The small inner ring represents 45° above the horizon
and the large ring represents the horizon. North is at
the top of the screen.You can use this to see which
satellites are obstructed by obstacles in your immedi-
ate area if you hold the unit facing north.
The GPS receiver is tracking satellites that are sur-
rounded by a black box. If the satellite number is not
surrounded by a box, then the receiver hasn’t locked
onto that satellite and it isn’t being used to solve the
position.
Beneath the circular graph are the bar graphs, one for each satellite in
view.Although the unit has twelve channels, it dedicates one channel per
visible satellite. Therefore, if only six satellites are visible, only six bar
charts show at the bottom of the screen.The higher the bar on the graph,
the better the unit is receiving the signals from the satellite.
The number in the upper left corner is the “expected horizontal position
error”or expected error from a benchmark location.In other words, if the
expected error shows 50 feet, then the position shown by the unit is esti-
mated to be within 50 feet of the actual location.However, this number is
only valid if you’re using DGPS or if S/A is turned off. Due to S/A, the
accuracy can only be less than 100 meters, 95% of the time, per U.S.
government specifications. Although the expected error is not accurate
unless you have a DGPS receiver, it does give you an indicator of the fix
quality the unit currently has.The smaller the expected error number, the
better (and more accurate) the fix is.
If the expected error is flashing, then the unit has not locked onto the

6
satellites, and the number shown is not valid.
The fix indicator on the left center shows either 2D or
3D.A 2D fix means the unit has locked onto three sat-
ellites and has calculated its position. A 3D fix means
the unit has locked onto at least four satellites and has
calculated both the position and altitude.(Remember,
it takes three satellites to determine the position - four
to determine position and altitude.) If neither 2D nor
3D are showing, then the unit doesn’t have the posi-
tion or altitude.
A battery level indicator on the lower right side of the screen shows ap-
proximately how much life is in the batteries. This runs from “F” (fully
charged) to “E” (expired).
A light bulb indicator at the top right corner of the screen appears when
the backlights are on.
FindingYour Position
Auto Search
To lock onto the satellites, the GPS receiver needs to know it’s current
position,localtime,anddate.(Elevation (altitude)isalsoused in the equa-
tion, but it’s rarely required to determine a position.) It needs this data so
thatit can calculate which satellitesshould be in view.Itthen searches for
only those satellites. When your GPS receiver is turned on for the first
time, it doesn’t know what your position or elevation (altitude) is. It does
knowthe current UTCtime and datesince these wereprogrammedintoit
at the factory and an internal clock keeps the time while the unit is turned
off. It begins searching for the satellites using the above data that it ac-
quired the last time it was turned on.This probably was at the Eagle fac-
tory.Since it’s almost certain that you’re not at the Eagle factory, it’s prob-
ablylookingforthewrongsatellites.If it doesn’t findthe satellites it’s look-
ingfor afterfiveminutes,it switchestoAutoSearch.Thereceiverlooksfor
any satellite inthe sky.Due to advancedtechnology,the auto search time
has shrunk to about five minutes, so the longest time you should ever
have to wait is ten minutes from the time you turn the unit on until it locks
onto the satellites and shows a position. Once the unit locks onto the
satellites, it should take less than a minute to find your position the next
time it’s turned on, provided you haven’t moved more than approximately
100 miles from the last location it was used.
Manual Initialization
If you don’t want to wait for the Auto Search, then you may be able to
speed up the initialization process by using the manual initialization fea-

7
ture.Usingthisfeaturetellstheunitit’sapproximateposition.Onceitknows
it’s location, it determines exactly which satellites should be in view and
starts looking only for those satellites.
To manually initialize the unit, press the MENU key.
Nowpressthedownarrowkeyuntilthe“GPSSETUP”
label is highlighted. Press the right arrow key. The
“INITGPS”(InitializeGPS)labelishighlighted.Press
therightarrowkeyagain.Thescreenatrightappears.
Use the arrow keys to move the crosshairs to your
approximate location on the map.You may use the
ZOUT key to zoom the map out. This will make it
easier and faster to find your location on the map.
Onceyouhavethecrosshairsonyourlocation,press
the ENT key.The unit returns to the satellite status screen.
Using the manual initialization method loads a position that’s close to
yours into the GPS receiver.It should now have position, time, and date,
thereby giving it the data it needs to determine which satellites are in
view.Once the satellites are known, the receiver searches for only those
satellites, making a lock faster than an auto search method.
Position Acquisition
When the receiver locks onto the satellites and calculates a position, it
shows the message “Position Acquired” on the screen. All position and
navigation data flashes until the unit acquires a position. Do not rely on
any data that is flashing! When the numbers are flashing, they represent
the last known values when the unit lost it’s lock on the satellites.
(Note:The altitude data may still flash even if the unit shows a “Position
Acquired” message and all other data is not flashing. The unit must be
lockedontoatleast foursatellites to determinealtitude.It only takesthree
satellites to determine position.You can navigate with this unit if the alti-
tude is flashing, simply ignore the altitude display until it quits flashing.)
REMEMBER, DO NOT NAVIGATE WITH THIS UNIT UNTILTHE
NUMBERS STOP FLASHING!
Once the unit has acquired the satellites and is showing a fix on the sta-
tus screen, or the position acquired message appears, it’s ready for use.

POSITION/NAVIGATION SCREENS
This unit has four modes: status, map, navigation, and window groups.
Use the PAGES and arrow keys to switch between the different screens.
The four screens that show by default are shown below.
STATUS NAVIGATION MAP WINDOWS
To change modes, simply press the PAGES key. A
screen similar to the one at right appears.Use the up
or down arrow keys to change modes. (The windows
mode is shown as “groups”.Group “A” is the first win-

section for more information.
Nav Screen #1
This screen has a compass rose that shows not only
your direction of travel, but also the direction to a re-
called waypoint. The navigation screen looks like the
one at right when you’re not navigating to a waypoint.
Your position is shown by an arrow in the center of the
screen. Your trail history, or path you’ve taken is de-
picted by the line extending from the arrow.The arrow
pointingdownatthetop of the compass rose indicates

9
the current track (direction of travel) you are taking.This is also shown in
the “TRK” (track) box at the top of the screen. On the example shown at
right, the track is 355°. The current ground speed (GS) shows in the box
in the lower center of this screen.
When navigating to a waypoint, Nav screen number
one looks like the one at right.Bearing to the destina-
tionwaypointisinthebox intheupperleftcorner.Bear-
ing is also shown by the large arrow pointing up to-
wards the compass, above the present position arrow.
Distancefromthepresentpositiontothewaypoint(DIS)
shows beneath the compass on the lower left side of
the screen.
Lines on either side of the present position show the
currentcross trackerrorrange.Cross trackerroris the
distance you are off-course to the side of the desired course line. The
courselineisan imaginaryline drawnfromyourpositionwhenyoustarted
navigating to the destination waypoint. It’s shown on the screen as a
verticaldottedline.The defaultforthe cross track error range is 0.25mile.
For example, if the present position symbol touches the right cross track
error line, then you are .25 mile to the right of the desired course.You
need to steer left to return to the desired course.The cross track error is
also shown in the“XTK” box.In the upper right corner
is the course (CRS) box showing the direction from
your starting position to the waypoint. Remember, a
course is a proposed path from the starting position to
the destination.Track is your actual direction of travel.
A circle depicting your destination (waypoint) appears
onthe screen as youapproachthe waypointas shown
on the screen at right.
Nav Screen #2
This navigation screen shows all navigation informa-
tionin large digital numbers.To viewthisscreen, press
the PAGES key, then press the up arrow key until the
“NAV1”label is highlighted.While it’shighlighted,press
therightarrowkey.Thescreen shownatright appears.
Press the EXIT key to erase the menu.
This screen is composed of eight digital boxes.Track
(TRK) and ground speed (GS) data are all that show if
you’re not navigating to a waypoint. If you are navigat-

10
ing to a waypoint, then bearing (BRG), distance to
waypoint (DIS), estimated time en route (ETE), cross
track error (XTK), destination arrow, and the CDI also
operate.See below for more information on the CDI.
Thedestination arrow shows the direction to the desti-
nation when the top of the screen is pointing in your
direction of travel.
Course Deviation Indicator (CDI)
Once navigation to a waypoint is established, the CDI
shows your distance to the left or right of the desired
course.The vertical line in the box shows both the di-
rection you must steer to get back on course and the
distance to the course line.For example, if you’re trav-
ellingstraighttowardsthedestination, from the start, then theline staysin
thecenter.If youdrift off course to the right,theline movesto the left .This
signifies that you need to steer to the left to get back on course.This is
called “chasing the needle”. If you steer towards the line (needle), you’ll
always be heading in the correct direction to get back on course.
The CDI’s range shows beneath the CDI label.On the above screen, the
CDI range is .20 mile, which is the default. You can adjust the range by
selecting the“ALARMS/CDI” label on the main menu.This is also shown
by the dotted lines at the far left and right side of the CDI.If the solid line
ison either of the dotted lines,thenyouare0.20mile offcourse.Remem-
ber, if the line moves to the left, then you are too far to the right of the
desired course line and vice-versa.
Using the CDI with a mapping screen helps you visu-
alizeyourpositionin relation to the course.The screen
on the right shows that we are off course to the right.
The vertical bar has moved to the left side of the CDI,
showing the direction to the desired course line. The
CDI gives you a quick, easy to read visual indicator of
your relationship between your direction of travel and
the desired direction.

Cursor
Pressing an arrow key turns on two dotted lines that
intersect at the present position symbol. These lines
are called a “cursor” and have a variety of uses.
To turn thecursor on, simplypress the arrowkeyinthe
direction you want the cursor to move. This lets you
view areas on the plotter that are away from your
presentposition.The zoom-in and zoom-outkeyswork
from the cursor’s position when it’s active - not the
present position.You can zoom in on any detail, any-
where.The cursor can also place icons and waypoints.
Press the EXIT key to erase the cursor. The unit centers your present
position on the screen after erasing the cursor.
Map Setup
The map has many customization options.To change
them,firstpress the MENU keywhile a map isshowing
on the screen. The map setup screen is highlighted.
Press the right arrow key. A screen similar to the one
at right appears.
Change Maps
Changes made to the map using the options in the
Map Setup is normally made to all map screens.The
change can be limited to the map screen currently in use, however, by
switching the “All Maps” to “This Map” in the “Change” menu.To do this,
simply highlight the “Change” label, then press the right arrow key. To
switch back, repeat the above.
Map Options
The following map options are listed under the “Map
Options” menu: Map Orientation, Auto Zoom, View
Destination, Range Rings, and Grids.
Map Orientation
By default, this receiver shows the map with north al-
ways at the top of the screen. This is the way most
maps and charts are printed on paper. This is fine if
you’realwaystravellingduenorth.What youseetoyour
left corresponds to the left side of the map, to your right is shown on the
rightside of the map,andso on.However,if youtravel any other direction,
the map doesn’t line up with your view of the world.

To correct this problem, a track-up mode rotates the map as you turn.
Thus,whatyouseeontheleft side ofthe screen should alwaysbetoyour
left, and so on.A course-up mode keeps the map at the same orientation
as the initial bearing to the waypoint.
In the north-up view shown at right, we're travelling
southeast towards camp, saved as waypoint number
14.In this view, the present position indicator appears
to move towards the lower right corner of the screen.
Inthetrack-upview, the presentpositionmoves straight
towardsthetop of the display. A "N" showstohelp you
seewhich direction isnorthwhenthe track-upmode is
on. Remember, in the track-up mode, the screen ro-
tates as you change direction. It always keeps your
direction of travel (track) heading towards the top of
the screen.
In the course-up mode, the screen is locked into your
original bearing tothe recalled waypoint,regardlessof
your track.
