INTRODUCTION

Welcome to the e xciting world of GPS! Whether you’ re a 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

satellites that are in view of your location. It’ s acquisition time and tracking

ability are second to none in its class.

The Global Positioning System (GPS) w as developed by the United States

Department of Defense as a 24-hour a day, 365 days a year global navi-

gation system for the military . Civilian availability was added (b ut with less

accuracy) using the same satellites. T w enty-four satellites orbit the Earth.

Three of these satellites are spares, unused until needed. The rest virtu-

ally guarantee that at least four satellites are in vie w of 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, (y our height abov e sea le v el - 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 vie w 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

calculated from position information. Theref ore, in order for it to determine

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 sho wn on the displa y.

S/A - What is it?

Another factor that greatly influences the receiver’s ability to deter mine

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 av ailability, 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 ov er 300 feet! Not

exactly pinpoint accuracy, but then fe w 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 tr ansmits correc-

tion signals that nullify the effects of SA. The DGPS receiver takes signals

from these land-based transmitters and gives them to the GPS receiver

which then uses them to show a more accurate position. The ironic part is

the federal gov ernment implemented SA and is also operating many DGPS

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 y ou 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. Alw a ys ha v e 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

your camp, f or example. It’ s up to you to saf ely navigate around obstacles,

no matter how you’re using this product.

GETTING STARTED

Po wer

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. If the power cable is used, the Map Guide Pro automatically s witches

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. W e 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 abov e batteries will last as long as stan-

dard alkaline batteries. We recommend DURACELL

brand, but others

will work. Do not use “hea vy-duty” batter-

ies or any type other than the ones listed

above. Do not mix different types of bat-

teries. (F or e xample, don’t use both alka-

line and ni-cad batteries at the same time.)

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 sho wn at right.

Install the batteries according to this dia-

gram. (There’ s a decal in the battery com-

partment showing the correct polarity,

also.) Replace the battery compartment

cover and the unit is ready f or use.

NiMH Battery

The DURACELL

DR-121 nickel-metal hydride (NiMH) battery replaces

the four standard batteries. It is sold as an accessory , (model BR-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 batter y that

can be recharged in this unit! Using the ex-

ternal power cable alone does not charge the

battery! You must use a charger supplied by

Eagle in order to charge the battery . Also , this

charger will only charge a DR-121. It will not

charge any other type of battery , including ni-

cads or rechargeable alkallines.)

OPERA TION

Keyboard

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

of operation are accessed using the PAGES

key. Press the MENU k ey to select or adjust

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 k eys are

used to enter or clear data or screens. Save

and edit waypoints using the WPT key. The

PWR key turns the unit on and off. Pressing

it once while the unit is operating turns on

the screen’s backlight. To prevent an acci-

dental shutdown, you must hold the PWR k ey do wn f or a f e w seconds in

order to turn the unit off.

Menus

Most of the unit’s f eatures are f ound on “men us’. Y ou can view the men us

by pressing the MENU key. This product has “Intelligent Menus”. There

are many menus that pertain to only the map, for example. When you

press the MENU key and the plotter is sho wing, menu items for the plotter

show in addition to the normal menus. For e xample, if the navigation screen

is showing, and you press the MENU ke y, plotter menu items won’t show

on the list. This helps you find the needed item without scrolling through

unnecessary menus.

Turning Power On

To turn the unit on, simply press the PWR key. A GPS

logo screen appears, then the screen similar to the one

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 sho ws a gr aphical

view of the satellites that are in view . Each satellite is sho wn on the circu-

lar chart relative to your position. The point in the center of the char t 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 e xpected error from a benchmark location. In other words , if the

expected error shows 50 f eet, then the position sho wn by the unit is esti-

mated to be within 50 feet of the actual location. Ho we v er , this n umber is

only valid if you’re using DGPS or if S/A is tur ned 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 hav e a DGPS receiv er, it does give you an indicator of the fix

quality the unit currently has. The smaller the expected error n umber , the

better (and more accurate) the fix is.

If the expected error is flashing, then the unit has not locked onto the

satellites, and the number shown is not v alid.

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 f our 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” (e xpired).

A light bulb indicator at the top right corner of the screen appears when

the backlights are on.

Finding Y our Position

Auto Search

To lock onto the satellites, the GPS receiver needs to know it’s current

position, local time, and date. (Elev ation (altitude) is also used in the equa-

tion, but it’ s rarely required to determine a position.) It needs this data so

that it can calculate which satellites should be in view . It then 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

know the current UTC time and date since these were programmed into it

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 f actory , it’ s prob-

ably looking for the wrong satellites. If it doesn’t find the satellites it’ s look-

ing for after five min utes, it switches to Auto Search. The receiver looks f or

any satellite in the sky . Due to adv anced technology , the auto search time

has shrunk to about five minutes, so the longest time you should ever

have to wait is ten min utes 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 ha ven’t mov ed 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 f ea-

ture. Using this feature tells the unit it’ s approximate position. Once it knows

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.

Now press the down arrow k ey until the “GPS SETUP”

label is highlighted. Press the right arrow key. The

“INIT GPS” (Initialize GPS) label is highlighted. Press

the right arrow key again. The screen at right appears.

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.

Once you hav e the crosshairs on your location, 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 f aster 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, the y 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

locked onto at least f our satellites to determine altitude. It only tak es three

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 NAVIGA TE WITH THIS UNIT UNTIL THE

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 f or use .

POSITION/NA VIGA TION 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 def ault are sho wn belo w.

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-

dows group .)

Press the right arrow key while the abov e menu is show-

ing to switch between diff erent versions of each mode.

When the desired screen appears, press the EXIT key

to erase the menu.

Navigation Screens

There are two different na vigation screens. Nav screen number one shows

a graphical view of your trip, Nav screen number 2 shows all navigation

details in large digital numbers. You can also customize both navigation

screens to show data other than the default. See the “Prog ramming Box es”

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 wa ypoint.

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 arro w. The arro w

pointing down at the top of the compass rose indicates

the current track (direction of trav el) y ou 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) sho ws in the bo x

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-

tion waypoint is in the bo x in the upper left corner. Bear-

ing is also shown by the large arrow pointing up to-

wards the compass, abov e the present position arrow .

Distance from the present position to the waypoint (DIS)

shows beneath the compass on the lower left side of

the screen.

Lines on either side of the present position show the

current cross track error range. Cross trac k error is the

distance you are off-course to the side of the desired course line. The

course line is an imaginary line drawn from your position when you started

navigating to the destination waypoint. It’s shown on the screen as a

vertical dotted line. The def ault for the cross track error range is 0.25 mile.

For e xample, if the present position symbol touches the right cross trac k

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 y our actual direction of tr a v el.

A circle depicting your destination (wa ypoint) appears

on the screen as you approach the waypoint as sho wn

on the screen at right.

Nav Screen #2

This navigation screen shows all navigation informa-

tion in large digital numbers. To view this screen, press

the PAGES key, then press the up arrow key until the

“NA V1” label is highlighted. While it’s highlighted, press

the right arrow key . The screen shown at right 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 na vigating to a wa ypoint. If y ou are navigat-

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.

The destination 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-

elling straight towards the destination, from the start, then the line stays in

the center. If you drift off course to the right, the line mov es to 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 bac k on course .

The CDI’s range sho ws beneath the CDI label. On the abo ve 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

is on either of the dotted lines, then you are 0.20 mile off course. 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-

alize your position in 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.

Map

The Map Guide Pro 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 map

screens show your course and trac k from a “birds-ey e”

view . If you’re na vigating to a waypoint, the map shows

your starting location, present position, course line, and

destination. You don’t have to navigate to a waypoint,

however, to use the map.

Using the map is as simple as pressing the PAGES

key, then highlighting “MAP 1”. A screen similar to the

one at right appears. The arrow flashing in the center

of the screen is your present position. It points in the direction you’ re tra v-

elling. The solid line extending from the arrow is your plot trail, or path

you’ve taken. The plotter’s range shows in the lower left corner of the

screen. In this e xample, the plotter’ s range is two miles from the left edge

of the screen to the right.

There are three different mapping screens. T o vie w the other map screens,

press the PAGES key, highlight the MAP label, and press the right arrow

key until the desired map screen appears. Press the EXIT key to erase

the menu. Map-2 (shown below) has navigation data added at the bottom

of the screen, beneath the map. The data includes bearing to waypoint

(BRG), track (TRK), and distance to wa ypoint (DIS).

MAP-1

MAP-2 MAP-3

Map-3 is similar to Map-2. It shows ground speed (GS), tr ack (TRK), and

the CDI at the bottom of the screen.

The Z-IN and Z-OUT keys zoom-in and out all maps to enlarge or reduce

their coverage area. The availab le ranges are: 0.1, 0.15, 0.2, 0.3, 0.4, 0.6,

0.8, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100, 150, 200, 300,

400, 600, 800, 1000, 1500, and 2000 miles.

Cursor

Pressing an arrow key turns on two dotted lines that

intersect at the present position symbol. These lines

are called a “cursor” and ha v e a variety of uses.

T o turn the cursor on, simply press the arrow ke y in the

direction you want the cursor to move. This lets you

view areas on the plotter that are away from your

present position. The zoom-in and z oom-out keys work

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, first press the MENU key while a map is showing

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 abo ve .

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’ re always tra velling due north. What you see to your

left corresponds to the left side of the map, to your right is shown on the

right side of the map, and so on. Howe ver , if you trav el 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, what you see on the left side of the screen should alw ays be to your

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 to wards the lo wer right corner of the screen.

In the track-up view , the present position mov es straight

towards the top of the displa y . A "N" shows to help you

see which direction is north when the track-up mode 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 to the recalled waypoint, regardless of

your track.

NORTH-UP

TRACK-UP

COURSE-UP

To select the desired mode, first press the MENU key, select “MAP 1

SETUP”, then select “MAP OPTIONS”. Finally , select “R OTA TE” and press

the right or left arrow key until the desired mode appears. Press the EXIT

key to erase this men u.

AUTOZOOM

This receiver has an autozoom f eature that eliminates much of the button

pushing that competitive units force y ou to make. It works in conjunction

with the navigation features. First, recall a waypoint. (See the waypoint

section for more information on navigating to a w a ypoint.) Then, with the

autozoom mode on, the unit zooms out until the entire course shows,

from the present position to the destination waypoint (recalled wa ypoint).

As you trav el towards the destination, the unit automatically begins zoom-

ing in, one zoom range at a time, keeping the destination on the screen.

The screens below show a slice of the progression of a trip near a lake.

Screen number one is the start and is on the 6 mile range. Intermediate

stages progressively zoom in as it gets closer to the destination.

To use the autozoom feature, first press the MENU key, select “Map 1

Setup”, then “Map Options”. Highlight “Auto Zoom”, then press the right

arrow ke y to turn it on. Press the EXIT key repeatedly to er ase the menus.

VIEW DESTINA TION

The GPS receiver normally centers the present position on the screen

and moves the map past it. If a waypoint is recalled, the unit can center

the waypoint on the screen, instead of the present position. To do this,

press the MENU key, select “Map 1 Setup”, then “Map Options”. Highlight

“View Dest”, then press the right arrow key to turn it on. Press the EXIT

key repeatedly to erase the men us.

Range Rings/Grid Lines

The map screen can be customized with rings that are 1/4 of the range

and/or grids that divide the plotter into equal segments of latitude and

longitude. To do this, press the MENU key, select “Map 1 Setup”, then

“Map Options”. Highlight the desired option, then press the right arrow

key to turn it on. Press the EXIT key repeatedly to erase the menus. A

sample screen of each type shows below.

RANGE RINGS GRID

BOTH RINGS & GRID

EARTH MAP OPTIONS

The earth map consists of the built-in background map

of the world. To change the Earth map options, first

press the MENU key, then select the Earth Map label.

Press the right arrow key. The screen shown at right

appears.

Earth Map On/Off

The background map can be turned on or off using the

“Earth Map” menu. The ear th map is the background

map that shows on the map screens. Simply highlight

the menu, then press the left arrow key to turn it off.

T ext Labels

Select “Map Text” to turn all names on the map (such as Lake Tahoe or

Mississippi River) off or on. The def ault is “on”. Press the left arrow key to

turn them off.

Locations

Normally, text disappears as you zoom out. This

declutters the screen, making it easier to see signifi-

cant map detail. T urning “Locations” on from the earth

map menu places a dot on the screen where a text

label should be when the screen is zoomed out. The

arrows on the screen at right show two locations where,

if zoomed in, text will show.

Map Detail

The detail shown on the background map diminishes as the screen is

zoomed out. This prevents cluttering of the display, or overlapping of text

and graphics which can make it unreadable. There are two detail levels:

EARTH MAP ON

EARTH MAP OFF

NORMAL DETAIL

HIGH DETAIL

normal and high. The difference between the two shows belo w. The screen

on the left is normal detail, on the right is high detail. Both screens are on

the 40 mile range. Normally , you’ll only see a diff erence in detail when the

unit is zoomed out to the 30 mile range or higher .

To change the map’s detail setting, select “Map Detail” from the ear th

map menu, then press the right arrow key.

Gray Fill

When this unit is first turned on, all water (lakes, oceans, rivers) is filled

with gray to distinguish it from land, which is clear. (See below) To make

the land fill with gray and water remain clear, select the “Gray Fill” label

from the Earth Map menu, then press the left arrow key. Press the EXIT

key repeatedly to return to the mapping screen.

WATER FILLED

LAND FILLED WITH

GRAY

Normally, you'll want to fill water with gray when you're using the GPS

receiver on land and fill land with gra y when y ou're using it on the w ater.
