INTRODUCTION
Thank you for purchasing an Eagle® AccuMap 12™. With its large LCD
screen, easy to use menus, and outstanding perf ormance, we think you’ll
be happy with this product f or many y ears .
The AccuMap 12 can be used for fishing, hiking, canoeing, offshore boating, and just about any other ground-based activity. This product also
takes IMS SmartMap™, C-MAP™, and Navionics™ cartridges, which
show greater detail of land and hydrog raphic f eatures.
Like most GPS receivers, your AccuMap 12 doesn’t have a compass or
any other navigation aid built into it. It relies solely on the signals from the
satellites to determine its position. Speed, direction of tra vel, and distance
are all calculated from position information. Therefore, in order for it to
determine the direction you’re travelling, you must be moving, and the
faster - the better . This is not to say the unit w on’t work at walking speeds
- it will. But the faster you travel, the easier it is for the unit to determine
your direction.
GPS works from satellites that transmit information to the world at very
high frequencies. One disadvantage to this frequency is that it’s “line-ofsight”. In other words, the signals don’t bounce around like your local
radio or television. If you don’t have a clear view of the sky, or if you’re
inside a metal building, the unit probably won’t be able to pick up the
signals from the satellites. This is common among all GPS receivers . W e
have f ound that using this product inside a car is usually sufficiently close
to the windows and windshield that it works well. However, there is an
optional remote antenna bracket and cable (model PA-2) that lets you
mount the removable antenna on top of the dash, in case it’s required.
Another factor that influences the GPS’ position and navigation capabilities is called selective av ailability or SA. This is small errors purposefully
injected into the transmitted signal from the satellites. The government
does this to degrade the system’ s accur acy to civilian and f oreign users.
Even with SA, GPS is the most accurate na vigation system ever inv ented
on such a large scale. The Gover nment’s accuracy specification is 100
meters horizontally and 150 meters vertically 95% of the time. In other
words, the position shown on your AccuMap 12 could be up to 100 meters
in any direction from your actual position, and the altitude could be plus or
minus 150 meters from what’ s shown on the screen, 95% of the time .
One way around the S/A problem is to purchase a DGPS receiver and
connect it to your AccuMap 12. A DGPS receiver (commonly called a
beacon receiver), picks up correction signals broadcast from ground sta
1
tions. The AccuMap 12 takes these corrections and applies them to the
position and altitude screens, giving you much better accuracy. Ev en with
S/A on, and without a DGPS receiver, your AccuMap 12 gives you outstanding position and navigation information.
Please sit down with the unit and this manual and f amiliarize yourself with
them before using this unit in the “real w orld”. A sim ulator is built in, which
lets you practice with the receiver.
INSTALLATION
The AccuMap 12 operates from six AA batteries or from 6 to 35 volts DC.
An optional cigarette lighter adapter is available (model CA-1) to plug into
a vehicle’ s electrical system. The AccuMap 12 automatically switches to
external power when it’ s plugged into the unit (pro vided that the e xternal
power is a higher v oltage than the batteries.) If, f or any reason, the e xternal power fails, the unit will automatically switch to the batteries. The
AccuMap 12 does not require batteries when the external power is in use,
however they make a good backup in case of power failure. An optional
rechargeable battery pack, (model RBP-E) has a nickle-metal hydride
battery and charger built into a pack that’s almost identical to the alkaline
battery pack that slides onto the bottom of the AccuMap 12.
An external antenna kit is also availab le (model PA-2) that allows the removable antenna to be mounted on a suction cup br ac k et up to four feet
awa y from the GPS receiv er.

BATTERY INSTALLATION
The AccuMap 12 requires six AA batteries. We recommend DURA CELL
alkaline batteries, but other brands will work. You can use lithium batteries
which will last longer than alkaline batteries (but cost more) or rechargeable ni-cad batteries (won’t last as long as standard alkalines). Rechargeable alkaline batteries such as RayOVac® Renewals® will also work .
Do not use heavy-duty batteries or any battery other than the ones listed
above. Do not mix different types of batteries. (For example, don’t use
both alkaline and ni-cad batteries at the same time.)
To install the batteries, first turn the AccuMap 12 so that it is facing you.
Now grasp the bottom part of the case and push it to the right until it
comes completely off the unit. The
bottom part of the case holds the
batteries. Next, push the battery
holder out the bottom of the battery
cover as shown below. Install each
battery with the negative end (-)
against the spring. The positive end
(+) of each battery should be firmly
against the metal plate. When all six
batteries are installed, slide the battery holder into the battery cover.
®
If the battery holder sticks when sliding into the battery cover, apply a
thin film of petroleum jelly to the “O”
rings on the battery holder.

IMPORTANT!
There are arrows molded into the bottom of the battery cover and battery
holder. Mak e certain the arrows are properly aligned! Otherwise, the battery holder won’t slide all the way into the cover and the battery pack
won’t slide onto the unit.
Slide the battery pack onto the unit and the AccuMap 12 is ready for use.
ANTENNA
Your AccuMap 12 has a removable antenna that folds over the display
when the unit is not in use. This prevents damage to the display. To open
the antenna, simply lift on an edge and raise it to the desired position. The
antenna is a quick release design, simplifying its remov al and installation.
To remove the antenna, push the antenna to the right (1), while simultaneously moving the antenna up (2), until it clears the AirMap's right side
(3). To replace the antenna, reverse the above steps. Make certain to
align the antenna with the AccuMap 12 until the antenna slides into place
to the left by itself. When it does, the antenna has mated with the connector inside the unit and it’s ready for use.

MAP CARTRIDGE INSTALLATION
The AccuMap 12 uses IMS SmartMap™ and WorldMap™, C-Map™, and
Navionics™ cartridges, all of which are packaged in a cartridge housing
specifically designed for Eagle mapping products.
The IMS SmartMap™ car tridges contain digitized data of over 120,000
bodies of water . Nearly all inland waterw ays-pub lic and private lakes , rivers, and streams, plus coastal United States waters up to 25 miles out are
included. There are also state and U.S. interstate highways and routes,
cities and towns. These inland mapping cartridges cover the entire continental United States in 64 highly detailed cartridges. The WorldMap™
cartridges cover all other areas of the world, showing more detail than the
background map , b ut not as much as the SmartMap™ areas.
The Navionics and C-Map cartridges cover most of the world with detailed views of coastal and some inland waters. Over 600 cartridges are
available.

OPERATION
Turning Power On
To turn the AccuMap 12 on, simply press
the PWR key. A screen similar to the one
at right appears. Press the EXIT key to
erase this screen.
MENUS
Most of the adjustments and features are
found on “men us”. Pressing the MENU k ey
lets you view the menus . Different menus
items are added or subtracted to the basic list, depending on which mode (mapping, navigation, or windows) the unit is
in. This gives y ou the features that are specific to the mode you are in, but also has
items that are used on all modes.
T o er ase the main menu, simply press the
EXIT key.
Finding Y our Position
Cold Start
When it’s turned on for the v ery first time, the GPS receiver doesn’t kno w
where it is, nor what the local time or date is. If you tell it your position,
time, and date, the unit will take less time to lock-on to the satellites and
give you a fix or position.
However, if you don’t want to push buttons at this time, that’s fine. The
AccuMap 12 will lock onto the satellites and give you a position without
any input from you. This is called a “cold-start”. It simply means that the
unit is searching without your help for the satellites that are in orbit. A
cold-start can take up to 5 minutes to acquire enough satellite data to
determine your position, although it typically takes less time than that.
Once the GPS receiver locks on to the satellites and finds y our position, it
stores the satellite data in its memory. The next time you use the unit, it
should take less time to lock on.
7
Once the AccuMap 12 locks on to the satellites and finds your position, it
stores the satellite data in its memory. The next time you use the unit, it
should take much less time to lock on.
To use your AccuMap 12, first take it outside,
awa y from trees and buildings. Y ou need a clear
view of the sky.
Open the antenna and adjust it so that it is
parallel with the ground. Press the PWR key.
Read the message on the screen, then press
the EXIT key to erase the message. A screen
similar to the one at right appears.
This is Map 3. Your present position is shown as a cross surrounded by a
diamond. As y ou wait f or the AccuMap 12 to find y our position, y ou’ll see
numbers flashing on the display. Anytime you see flashing numbers, it
means the AccuMap 12 does not have a position! Do not rely on an y data
that is flashing! When the numbers stop flashing, the unit has loc ked on to
the satellites and the position is good.
That’s all y ou have to do to find y our position. The time displa y may not be
correct when the cold start method is used. See the manual initialization
section for details on changing the time.
Finding Y our Position
Initialization
A cold-start as described above can take up to 5 minutes to find your
position. There is another method to initialize the AccuMap 12 that ma y let
it acquire the satellites faster . Man ually entering your position, local time
and date will help the GPS receiver determine which satellites are available and lock on to them f aster. There are two wa ys to input your position.
You can locate your position on the receiver’s map or enter your latitude
and longitude. Remember, once the receiver finds its position, it stores
the position into memory. The receiver won’t
have to initialized the next time you it on.
Enter by Map
To show the receiver your approximate location on its map, first press the MENU ke y , then
the up or down arrow keys until the “GPS
SETUP” menu is highlighted as sho wn at right.
Now press the right arrow key. The screen
shown at the top of the next page appears .
8
Using the down arrow key, highlight the “Initialize GPS Receiver” menu, then press the
right arrow key. The screen shown below appears next.
This is the GPS initialization screen. The position, altitude, time, and date the GPS receiver
is currently using to find the satellites is shown
at the bottom of this screen. Changing these
values to your local position and time will speed
the position lock.
T o change the position, highlight the “EDIT LA T/
LON label, then press the right arrow key. A
screen similar to the one at right appears. With
the “INPUT FROM MAP” label highlighted,
press the right arrow key. The screen below
appears.
The mapping screen appears with two lines
that intersect at the center. These lines are the
cursor. Using the arrow keys, mov e the cursor
to your present position. You can use the Z-IN
and Z-OUT keys to zoom in or out to find y our
area on the map. Once you have the cursor
close to your location, simply press the ENT
9
key. The unit returns to the GPS SETUP menu with your local latitude
and longitude showing in the box at the bottom of the screen.
Enter Manually
To change the position by manually entering
the latitude and longitude, press the MENU key,
then highlight the “GPS SETUP” label and
press the right arrow key. Now press right arrow key again while the “EDIT LAT/LON” box
is highlighted. The screen shown at right appears. Highlight the “INPUT MANU ALLY” label
and press the right arrow key. The screen
shown below appears.
If your latitude is south, press the up or down
arrow key to change it. If it is north, press the
right arrow key to highlight the first number in
the latitude. Now press the up arro w key to increase the number or the down arrow key to
decrease it. Once the first number in the latitude is set, press the right arrow key once to
move to the ne xt number in the latitude .
Keep pressing the arrow k eys until the latitude
and longitude are set to your local position. (Note: This position does not
have to be v ery accurate. If y ou can get it within one degree of your actual
position, that will be fine.) When it’s set, press the ENT ke y . The AccuMap
12 accepts your entry and returns to the GPS setup menu.
Now change the local time and date if they’re incorrect on this screen by
highlighting the appropriate label and pressing the right arrow key. (Don’t worry about altitude.) When everything is acceptable, press
the EXIT key to return to a mode screen. The
AccuMap 12 will instantly use the data you entered to find the satellites in the sky. (The unit
knows which satellites will be available at the
position, date, and time you entered. Therefore, it will only look for those satellites, making the search time much shorter than a cold
start which looks for all of the satellites until it
finds three.)
10
IMPORTANT!
If the data shown in digital numbers on any screen is flashing, it means
that data is invalid. DO NOT RELY ON ANY NUMBERS THA T ARE FLASHING! Usually , this happens when the GPS receiver has lost its loc k on the
satellites. The data that is flashing was the last kno wn when the unit lost
its navigational capability .
DO NOT NAVIGATE WITH THIS UNIT UNTIL THE DATA STOPS
FLASHING!
POSITION/NA VIGA TION DISPLAYS
The AccuMap 12 has navigation, mapping, and windows group modes.
These screens were designed to show data that is used most often. Many
of the navigation, mapping, and windows screens can be customized to
show data other than the ones chosen by the f actory . See the Reprog ram
Groups section for more details.
The three default displays are shown below. To
change displays, simply press the PAGES key. A
screen similar to the one at right appears. Now
press the up or down arrow keys to change modes .
(The windows display is shown as "Groups". For
example, Group A is the first windows group on
the PAGES menu.) Press the right arrow key to
see more screens on each mode. When the desired screen appears, press the EXIT key to clear
the menu.

Navigation Screens
There are two navigation screens. Nav screen number one sho ws a graphical view of your trip , the other screen shows all navigation details in large
digital numbers.
Nav Screen #1
This screen is dominated by a compass rose.
Your track (direction of travel) is indicated by
an arrow pointing down toward the compass
rose at the top center of the screen. Track is
also shown in the upper right corner of the display under the “TRK” label. In the example
screen shown at right, the track is 355°. The
line extending behind the arrow in the center
shows your trac k history.
Your speed over ground or Ground Speed is shown at the bottom of this
screen. In this example, the ground speed is 21.3 miles per hour. The
screen looks like this when you’ re not navigating to a wa ypoint. (See page
39 for information on wa ypoint navigation.) If y ou navigate to a w a ypoint,
the screen looks like the one below.
The bearing to the destination waypoint is
shown in the upper left corner of the screen.
Bearing is also shown by the large arrow pointing up to the compass.
The numbers on either side of the center arrow show the cross track error range . In other
words, (using the screen at right as an example) if the arrow crosses the dark band on
either side, you are .10 miles to the left or right
of the desired course.
A circle depicting your destination appears on
the screen as you approach the waypoint, as
shown here.
The digital boxes at the bottom of the screen
show (from left to right) your distance to go to
the destination (DIS), estimated time en route
(ETE), ground speed (GS), and course (CRS).
Course (CRS) is the bearing from your starting location to your destination. (Remember,
12
course has nothing to do with your present position, except f or your starting location.) It’s shown as a dotted line on the NAV 1 display. This is
shown as a reminder so that if you de viate from your original course, y ou
can easily return to it. (A “course” is a proposed path over the ground. A
“track” is y our actual path over ground.)
All of the digital boxes on this screen are programmable. See the “Programming” section f or more inf ormation.
Nav Screen #2
The navigation screen shows navigation inf ormation in large digital numbers. To vie w this screen, press the PAGES k e y, then press the up arrow
key until the black box surrounds the “NAV 1” label. Now press the right
arrow key. A screen similar to the one belo w appears. Press the EXIT key
to erase the menu.
This screen is composed of eight digital display boxes, showing your track (TRK), and
ground speed (GS). The other boxes show
navigation data when a waypoint is recalled,
including bearing to the waypoint (BRG), distance to waypoint (DIS), velocity made good
(VMG), estimated time en route (ETE), local
time (CLOCK), and a CDI. The CDI is a course
deviation indicator, showing your distance to
the left or right of the desired course.
You can reprogram all of the digital box es on the NAV 2 screen. See the
"Programming" section for more inf ormation.
COURSE DEVIATION INDICAT OR (CDI)
The CDI shows your distance to the left or right
of the desired course to a waypoint. (In order
to use the CDI, you must first recall a w aypoint
or route. See the Navigation section for more
details.) The arrow in the center of the box
shows the direction to the destination. For example, if you’re travelling
straight towards the waypoint, the arrow points straight up. If you turn to
the right, the arrow points to the left, showing that the destination is to
your left.
13
The smaller arrows pointing down on each side
show the CDI’ s range. The def ault is 1/10 mile.
The small vertical bar shows the distance off
course and represents the course line. If the
bar moves to the right, then you are to the left
of the desired course line, and vice-versa. The CDI indicator shown above
shows that we are about .02 miles to the left of the desired course. (With
the CDI range of .10 miles, each vertical dotted line represents .02 mile.)
You can adjust the CDI’s range through the “Alarms/CDI” men u.
Using the CDI with a mapping screen helps you visualize your position in
relation to the course. The screen belo w left shows that we are on course.
The CDI arrow is pointing straight ahead and no off-course bar is showing. Looking at the screen on the right, howe v er , y ou can see that we are
off course to the right. In f act, w e are so far off course that we exceeded
the range of the CDI. The vertical bar has gone off the scale on the left
side of the CDI. A small arrow points to the left, 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 tra v el and the desired direction.
Mapping
The AccuMap 12 has a ground map of the world built inside. This map has
the majority of its detail in far southern Canada, the continental United
States and Hawaiian islands, northern Mexico,
the Bahamas, and Bermuda. The bac kground
map shows when the AccuMap 12 is first
turned on, with or without a map cartridge.
There are three different mapping screens
availab le. Map screen number 3 shows b y default, as shown at right. Your current position
displays at the center of the screen by a cross
surrounded by a flashing diamond.
14
MAP 1 MAP 2 MAP 3
To view the other mapping screens, press the PAGES key. Press the up
or down arrow key to highlight the "MAP 1" label. Now press the right or
left arrow key to select a diff erent mapping screen. Press the EXIT k ey to
erase the pages menu.
Maps 2 and 3 (as shown above) have navigation data displayed using
digital numbers. The digital displays on map 3 can
be rearranged or changed to other displays. See
the “Reprogram Boxes” section for more information.
As you move, the map slides past your present
position, which always remains at the center of the
screen. The line extending from your position sho ws
the path you’ve tak en.
Use the Z-OUT and Z-IN keys to enlarge or reduce the mapping area. If
you have an IMS SmartMap™ cartridge installed, it’s detail typically begins showing when you zoom in to the 10 mile r ange.
Map Cursor
Pressing an arrow key while a map is on shows two dotted lines that
intersect at your present position. These dotted lines are called a “cursor”
and have a v ariety of uses.
You can move the cursor around the display b y pressing the arrow ke ys in
the direction you want it to move. This lets you view different areas of a
map, away from your present position. When it’s turned on, the zoom-in
and zoom-out keys w ork from the cursor’s position - not the present position, so you can zoom in on any detail, anywhere while na vigating.
15
The latitude/longitude of the cursor shows in the box at the top of the
screen whenev er the cursor is activ ated.
CURSOR OFF
CURSOR ON
The map cursor is also used to place and erase icons and waypoints .
AUTOZOOM
Generally, when you travel using a mapping receiver like the AccuMap
12, you spend some amount of time zooming in and out, looking at detail
or the whole route between the start and destination.
The AccuMap 12 has an autozoom feature that eliminates much of the
button pushing that competitive units force you to make. It works in conjunction with the navigation feature . First y ou must recall a waypoint. (See
the waypoint section for more information on navigating to a waypoint.)
When you turn the autozoom mode on, the AccuMap 12 zooms in on y our
present position. As y ou travel tow ards the destination (recalled waypoint),
the AccuMap 12 begins zooming out, showing more of your course to the
waypoint. After you cross the halfway point to your destination, the
AccuMap 12 zooms in closer, one zoom range at a time, keeping the
destination on the screen. Nearly every time it zooms in, you can see
more detail. This is a benefit for two reasons. Number one, you want to
see more detail as you get closer to the destination, especially if you’ve
never been there before. Two, it takes a load (small, perhaps, but still
another thing to keep track of) while y ou’re occupied with other details.
The screens at the top of the next page show a slice of the progression of
a trip on an area lake. Screen number one is the start and is on the 1 mile
range. Intermediate stages progressively zoom out, until you’ re at the midway point. The AccuMap 12 then begins zooming in as you get closer to
the destination.
