Tips:
•Setting the correct battery
type will optimize the bat-
tery’s performance. For more
information on selecting bat-
tery type, see To Modify the
System Settings on page 67.
• Because the Earthmate GPS
PN-20 has a real-time clock
that requires power even
when the device is powered
off, your batteries are con-
stantly in use. If you use your
Earthmate GPS PN-20 spo-
radically (for example, more
than a month between uses),
remove the batteries for
long-term storage and then
reinsert them when you want
to use the device.
Thank you for purchasing the DeLorme Earthmate GPS PN-20. This versatile and compact GPS receiver lets you create tracks of your travels, create routes so you never get lost, find points of interest,
and more!
This manual provides instructions for using all of the functionality available on the Earthmate GPS
PN-20. Most of the chapters are based on pages, which are the main screens on the Earthmate GPS
PN-20. Each chapter describes the features of that particular page and the menu options that are
available from that page. In addition, this manual also discusses basic functions (such as map panning, battery information, map data information, and more), as well as frequently asked questions,
warranty information, and so on.

About GPS
What is GPS?
The Global Positioning System (GPS) applies modern technology to the ancient art of navigation.
The U.S. Department of Defense has developed and launched a series of positioning satellites in an
orbiting “constellation.” These satellites are used as reference points much the same way stars have
been used in conventional navigation.
Using these satellites, a GPS receiver can determine your position anywhere on the globe. GPS provides accurate information about coordinate position, elevation, speed, and direction of travel. Many
people have discovered the benefits of GPS for recording tracks and much more.
How Does GPS Work?
The GPS constellation consists of at least 24 satellites, each carrying several atomic clocks to ensure
the most accurate time possible. The satellites broadcast low-power radio waves containing the satellite’s identity code and the exact time (to the nanosecond) that the message was sent.
When a GPS receiver picks up a satellite signal, it identifies the satellite and compares the signal time
with its own clock. The time difference represents the time it has taken for that radio wave to travel
6
from the satellite to the receiver. Since radio waves travel at the speed of light, the time difference
can be used to calculate the distance from the satellite to the GPS receiver.
Getting Started
The satellite’s identity code provides the location of the satellite, and the distance to the receiver
creates a sphere of possible locations for the GPS receiver. Without more information, the receiver
knows only that it is located somewhere on that sphere.
Two additional satellites are necessary to narrow down the receiver’s position. Each of these satellites sends a similar radio message containing time and identity information. The GPS receiver checks
the orbital location of each satellite and uses the elapsed time to create two additional spheres of
possible locations. These three spheres intersect at two points; however, one of these points is eliminated because it is far away from the Earth’s surface. Therefore, the second point is assumed to be
correct. The data from these three satellites provides the receiver with a two-dimensional location.
Data acquired from a fourth satellite pinpoints the receiver’s exact location. This additional positioning
information allows the GPS receiver to calculate its elevation, which is particularly important for GPS
users in mountainous locations.
GPS Position Accuracy
Any buildings, natural structures, or heavy foliage that obstruct the GPS antenna’s view of the sky
prevent satellite signals from reaching the receiver and decrease the accuracy of your position.
Note: Placing the Earthmate
GPS PN-20 in a backpack pocket or jacket should not result
in problems with GPS position
accuracy.
Frequently Asked Questions
Can I install non-DeLorme maps on the Earthmate GPS PN-20?
DeLorme’s professional GIS software, XMap ®, allows you to register non-DeLorme maps and
transfer them to the Earthmate GPS PN-20.
How can I improve the life of my batteries?
When the backlight is on, it consumes a large part of the battery. Changing the backlight timer to turn
off after 15 seconds could double the life of your batteries. For information on changing the backlight
timer, see To Modify the Backlight Timer on page 68.
Other ways to increase the life of the batteries include:
• Removing your batteries for long-term storage
7
• Setting the GPS Settings to Power Saving mode
• Disabling GPS while indoors
• Using batteries with higher milliamp ratings (such as Duracell Ultras, Energizer E2s, etc.)
Why are the new batteries that I put in the device the last time I used it (a month ago) already
dead?
Because the Earthmate GPS PN-20 has a real-time clock that requires power even when the device is
powered off, your batteries are constantly in use. If you use your Earthmate GPS PN-20 sporadically
(more than a month between uses), remove the batteries for long-term storage and then reinsert
them when you want to use the device to improve battery life.
Why does it take so long to find satellites?
Acquiring satellite data takes longer if the batteries are low or if the Earthmate GPS PN-20 does not
have a clear view of the sky. Be sure that trees, buildings, and other obstacles are not blocking the
Earthmate GPS PN-20 when you begin tracking.
Other factors, such as if you haven’t used the device for a long time or if you’ve moved the device a
great distance from its last location, can affect the amount of time it takes to find satellites.
Note: The charging circuit in
the PN-20 was designed for optimum operation with the RCRV3 Li-Ion battery sold through
DeLorme. Other RCR-V3 Li-Ion
batteries may work and charge
in the PN-20, but DeLorme can
make no guarantees of compatible operation.
8
How do I reset the Earthmate GPS PN-20 when it will not turn off?
You can reset the Earthmate GPS PN-20 by holding the Power button for seven seconds. If that does
not work, remove and replace the batteries to reset the Earthmate GPS PN-20.
Why won’t my Lithium-ion battery hold a charge?
The Li-ion battery is designed to last for 300-500 uses, depending on environmental conditions.

Scenarios
You can use your Earthmate GPS PN-20 for a variety of activities, including:
• Geocaching
• Bird watching
• Biking
• Managing GIS data
• And much more!
Below are some scenarios for using the Earthmate GPS PN-20 in these situations.
Seeking a Geocache
Geocaching is a popular hide-and-seek sport for GPS users. Hiders place a cache (prizes and/or log
book) at an approved location and seekers use the hiders’ clues (coordinate information and clues that
are shared via the Internet—for some geocache locations, visit www.geocaching.com) to find the
cache. The cache usually contains a variety of prizes for the successful seeker (seekers are encouraged to observe the “take one, leave one” policy on prizes in the cache).
Mike and his family are looking for a fun weekend activity that they can enjoy in the great outdoors.
A coworker tells Mike about geocaching and they decide to try the activity with their new Earthmate
GPS PN-20.
Before they leave for their adventure, they visit www.geocaching.com to find a cache in their area.
Once they find a cache, they use their compatible DeLorme mapping program to see the geocache
on the map and then download a map package of the area.
1. Visit www.geocaching.com and select the geocache you want to try to find.
2. Save the geocache’s .loc file to your computer.
3. Open your DeLorme program and click the Draw tab.
4. Click File to open the draw file editing area.
5. Click Import. The Import Draw File dialog box displays.
6. From the Files of type drop-down list, select LOC file (*.loc).
11
Navigate to the geocache
7. Browse to the location where you saved the .loc file in step 2, select the file, and then click
Open. The draw objects in the imported file display. A new waypoint layer is automatically
created for the imported file.
8. Click Done to return to the Draw dialog area.
9. Click the Handheld Export tab in your software.
10.With the map centered on the geocache area, click the Select/Edit tool and then click the
grids on the map that cover the map area you want to export to the Earthmate GPS PN-20.
11. Name and save your map package.
12.Click the Exchange button on the Handheld Export tab or in the toolbar.
13.Send the geocache waypoint layer and map package to the device and then click Done.
Once the map and waypoint are loaded on the Earthmate GPS PN-20, they use the Waypoints Page
to locate the coordinate that was provided in the cache’s clue. Once the waypoint is found, they create a route from their current position (home) to the waypoint location.
14.Press MENU and then select Waypoints.
15.Highlight the geocache waypoint in the list and then press ENTER.
16.Use the arrow keypad to highlight the Route button and then press ENTER.
17. Use the arrow keypad to highlight the Navigate button and then press ENTER.
18.Press PAGE until the Compass Page displays.
19.Use the Compass Page to find the direction of travel. The bearing arrow (large green arrow)
points in the direction of the next stop in the route. Use the bearing arrow to determine the
correct direction of travel towards the waypoint.
Once they arrive at the cache, they take a trinket from the cache and leave a pencil they bought while
on a recent trip to Niagara Falls. Then they update the waypoint symbol on the Earthmate GPS PN-20
to the geocache found symbol. When they return from their adventure, they visit the cache’s page on
www.geocaching.com and enter a log about their experience.
Hiding a Geocache
Mike and his family had so much fun on their first geocache outing, that they decide to create a
geocache of their own!
12
The family decides to hide the cache along a public trail approximately 10 miles from their home.
Before they can add the cache to geocaching.com, they must get a very accurate coordinate for the
location where they’re hiding the cache. To do so, they must mark a waypoint at the geocache location
and then use the Averaging function on the Earthmate GPS PN-20. When a waypoint is averaged, a
series of GPS readings for the waypoint’s location is recorded and averaged to increase the positional
accuracy of the waypoint.
1. Ensure you have a 3-D signal at the location of the geocache.
2. Press the Mark button. A waypoint is placed at the current GPS location.
3. Highlight the default waypoint symbol and press ENTER. Use the arrow keypad to select
the geocache hidden symbol and press ENTER.
4. Highlight the default label and press ENTER. Enter the new label “Our First Geocache” using
the keyboard, highlight OK, and press ENTER.
5. Highlight the Comment field and press ENTER. Enter the comment information (“Hid cache
under pile of sticks”) using the keyboard, highlight OK, and press ENTER.
6. Highlight the Avg button and press ENTER. The GPS status, coordinates, elevation, number of
readings at the location, and estimated accuracy display. The positional accuracy of the way point is increased by the number of recordings. A small estimated accuracy number indicates
that the waypoint is very close to its actual coordinates.
7. Highlight the OK button and press ENTER.
8. Use the arrow keypad to highlight the Save button and then press ENTER.
Once the geocache location point is averaged, they visit www.geocaching.com and create a new
geocache with the averaged coordinate.
Scenarios
Marking the “Our First Geocache” waypoint
Bird Watching
The Earthmate GPS PN-20 is a perfect companion for bird watching. With aerial imagery loaded on the
Earthmate GPS PN-20, bird watchers can see clearings, tree cover, geological features, and more. In
addition, they can use the waypoint function to mark waypoints on the map when they see particular
types of birds. They can also use the track functionality to create a breadcrumb trail while they’re traveling to their bird watching spot and then follow that track back to their vehicle so they do not get lost.
13
Safety Tip: Be sure to bring a
map and compass with you on
your expedition in case the batteries in your Earthmate GPS
PN-20 are low.
Editing the track settings
Tip: Use the Time option if you
want to record a lot of detail.

are going to make many steps
along the way.
14
In the scenario below, Tom, a bird watcher, uses the Earthmate GPS PN-20, aerial imagery, and the
Earthmate GPS PN-20 Online Map Center to prepare for his expedition.
Before Tom leaves for his trip, he uses the Earthmate GPS PN-20 Online Map Center to download
additional map data so he can get satellite and aerial views of the area where he’ll be. This is helpful
to Tom because he has heard that the bird population is greater near the swamp land. With the aerial
and satellite data available from the Online Map Center, Tom can see the geological formations in his
bird watching area before he leaves, giving him a greater idea of where he should spend his day.
1. Visit http://data.delorme.com to download the area where you will be bird watching.
Once the map of the location is saved on the Earthmate GPS PN-20, Tom leaves for his bird watching
trip. When he arrives at the location, he parks his truck, turns on the Earthmate GPS PN-20, waits
until he gets a 2-D or 3-D fix, places a waypoint to represent the parking lot, modifies his tracking
settings, and then turns on Track recording.
2. Press and hold the Power button to turn on the Earthmate GPS PN-20.
3. Press the Mark button on the device to place a waypoint at the parking lot location and press
ENTER.

If the On button is already activated, go to step 10.
Tom continues his journey to the bird-watching spot. While he’s walking, he notices an eagle in a tree
and wants to use his Earthmate GPS PN-20 to mark a waypoint at the bird location.
10.While at the spot of the tree, press the Mark button.
11. Scroll to the top of the Waypoints screen to highlight the waypoint symbol and press ENTER.
Use the arrow keypad to find and highlight the bird icon and press ENTER.
12.Scroll to the label text field (to the right of the bird icon) and press ENTER. Use the arrow key
pad to highlight the letter E and press ENTER. Repeat this step for each letter in the word
“Eagle.” When you’re finished, highlight OK and press ENTER.
13.Scroll to highlight the Save button and press ENTER.
When he arrives at the desired bird watching spot, he saves his track log, turns off the GPS device,
and spends the day bird watching.
14.Press MENU, select Tracks, and press ENTER.
15.Scroll to highlight the Save button and press ENTER.
16.Press the Power button to turn off the Earthmate GPS PN-20. Press ENTER when prompted.
When he’s finished for the day, he turns the GPS device back on, waits until he gets a 2-D or 3-D fix,
and then follows his track to where he started—ensuring he won’t get lost. The process of following
his initial track creates a new route that he can use to navigate back to the parking lot.
17. Press and hold the Power button to turn on the Earthmate GPS PN-20.
18.Press MENU, select Tracks, and press ENTER.
19.Select the track that was saved earlier that day and press ENTER.

Mapping Assets in the Field
Scenarios
Up-to-date maps are often critical to efficiently manage and maintain company assets. You may need
several layers of information to locate and update information about these assets in the field, such
as road, topographic, and historic maps, as well as high-resolution aerial imagery and GIS layers. The
Earthmate GPS PN-20 is ideally suited to handle these needs; you can transfer virtually any type of
data from DeLorme software onto the device for use in the field, and then use the Earthmate GPS
PN-20 to map new assets and the conditions of existing assets. You can then bring this information
back into the office to update the central database.
The division managers of a utility company are responsible for overseeing the bi-monthly update of
the spatial database for each division. They must collect information regarding new line locations,
conditions, and areas requiring repair or replacement to update the database and assist in planning
for the next month’s maintenance schedule.
The company uses the Earthmate GPS PN-20 with DeLorme’s professional XMap ® GIS software
to perform the updates. Each division is divided into quadrants with crews of two assigned to each
quadrant. Each crew has an Earthmate GPS PN-20 and is responsible for uploading the maps and
data they need on the device before heading out into the field. This data includes an updated copy of
the quadrant’s GIS utility line layer, road and topographic maps, waypoints of pole mile markers, highresolution aerial imagery downloaded from the state GIS department, and digitally scanned paper
maps of utility line schematics. These maps are geo-registered to the DeLorme map using XMap.
Preparing data for and transferring data onto the Earthmate GPS PN-20
1. Open XMap, set up a subscription to the central database, and obtain an updated copy of the
utility layer for the division.
2. Load the GIS layer into the GIS tab and use the spatial query tool to isolate the line objects
within a particular quadrant.
3. From the ImageReg tab, open the digital image of the schematic map for the quadrant. Use
the GIS line layer as reference to place points on the digital image that correspond to points on
the DeLorme map. Then, process the image to geo-register it to the map.
4. Visit the state GIS website and download any digital aerial imagery in .sid or .tiff format that
corresponds to the quadrant. Use the Map Data tab to load the imagery into XMap.
17
5. From the Handheld Export tab, center the map on the quadrant and customize the handheld
grid size to best fit the area. Then, click the Select/Edit tool and select the grids on the
map that cover the quadrant.
6. Click the Options button and select the check box next to each dataset to transfer to the
Earthmate GPS PN-20. For high-resolution aerial imagery, select XMap Raster Data Snapshot.
For topographic, road, and GIS data, select XMap USA Topographic Data. For scanned historic
maps, select the ImageReg Data series. Customize the display ranges of the datasets based
on your preferences.
7. Name and save the map package. Then, click the Exchange button on the Handheld Export tab
or in the toolbar. Send the mile marker waypoint layer and saved map package containing the
road, topographic, historic, and aerial imagery maps to the device and then click Done.
Using the Earthmate GPS PN-20 in the field
With all the data transferred to the Earthmate GPS PN-20, the field crew for each quadrant is ready
to head into the field to update and verify the utility data. One field crew is responsible for updating a
quadrant with significant additions and changes to the existing infrastructure. They have a list of mile
marker ranges where these changes took place.
1. Use the Routes option on the Earthmate GPS PN-20 to create a route from the field office
(current GPS location) to the utility waypoint mile marker next to the service road entrance.
2. Once the field crew arrives at the entrance, the worker with the Earthmate GPS PN-20 directs
the driver to each mile marker on the list where utility additions and modifications were made.
They use the bearing and distance information for each waypoint to navigate along the service
road. Once they are parallel to a mile marker, they set out on foot to the pipeline, using the aerial
imagery, topographic, and GIS data to give them field reference.
3. Once the line locations are located, the crew collects pertinent waypoints and tracks on the
Earthmate GPS PN-20 to record information about the line. They use the various waypoint
symbols on the Earthmate GPS PN-20 to represent different features, such as areas in need
of service or areas where there are dangerous trees that need to be removed. When they
come across an area where the GIS data does not correlate with the location of the utility line
in the field, they record a track for that length of segment and drop waypoints at each line vertex.
4. When the field crew is finished, they return to the office and download the waypoints and
18
5.
6.
tracks to XMap. Then they review the data to update any labels that need clarification and put
additional notes for the points using the mapnote feature in the Draw tab.
Once they are finished with the review, they synchronize their field data to the central database
using the synchronize feature in XMap.
The next day, the database manager responsible for the division reviews their synchronized
data against the corporate GIS layer and updates the corporate layer within XMap.

The Satellites Page
Viewing the Satellites Page
Once you turn on the Earthmate GPS PN-20, the Satellites Page displays. The Satellites Page informs
you of your current GPS status, the number of satellites the Earthmate GPS PN-20 is acquiring data
from, the signal strength, and the GPS accuracy (available only when a 2-D or 3-D fix is obtained).
Satellites Page
Tip: If it is taking a long time for
the device to obtain a 2-D or 3-D
fix, verify it has a clear view
of the sky. Be sure that trees,
buildings, and other obstacles
are not blocking the Earthmate
GPS PN-20. If the device still
cannot obtain a 2-D/3-D fix,
press PAGE until the Satellites
Page displays, press MENU,
highlight the Set Current Location option, and then press
ENTER. The Map Page displays
automatically. Pan the map to
your current location and press
ENTER.
20
GPS and WAAS Status
GPS status displays in the upper-left corner of the page and displays the following, depending on your
satellite acquisition status:
• GPS Off—The GPS is disabled.
• No Fix—The GPS cannot find sufficient satellite data to determine your current GPS position.
• 2-D—The GPS connection is successful, but the connection quality is not quite as sufficient as a
3-D fix. This usually indicates insufficient data for an accurate location because only three
satellites are being used or signals from the satellites are poor. Move your receiver to another
location until you get better reception.
• 3-D—The GPS receiver is receiving sufficient satellite data to determine your location.
If WAAS displays in the upper-right corner of the page, the Earthmate GPS PN-20 has obtained a
WAAS connection. WAAS provides up to five times greater position accuracy than a regular 2-D or
3-D connection. WAAS is available only in North America.
Satellite Constellation and Signal Graph
Both the satellite constellation and the satellite signal graph display visible satellites and their identifying numbers, which are assigned by the Department of Defense.
In the satellite constellation, satellite-shaped icons display each satellite’s position in the sky relative
to the device’s current position.
In the satellite signal graph, each satellite is represented as a bar that is sized according to signal
strength. Longer bars have greater strength and shorter bars have less strength.
The icons in the satellite constellation and the lines in the signal graph are color coded based on the
quality of the data they are transmitting:
•
•
•
Red—Indicates your GPS receiver is tracking the satellite, but it is not receiving data from it.
Green—Indicates your GPS receiver is tracking the satellite, ephemeris data is available, and the
satellite is being used for navigation.
Blue—Indicates your receiver is tracking the satellite, ephemeris data is available, the satellite is
being used for navigation, and the satellite has WAAS corrections available.
GPS Accuracy
The GPS accuracy displays in the lower-left corner of the screen in feet or meters, depending on the
measurement preferences you assigned in the Device Setup Page (see To Modify the Units Settings
on page 71 for more information). GPS accuracy is represented on the map by a circle with a radius
equal to the GPS accuracy, allowing you to see a representation of your accuracy in relation to your
map scale. The accuracy of the Earthmate GPS PN-20 is +/- 10 meters.
Battery Indicator
The battery indicator is a graphic representation of the current available battery power. It displays
differently based on the current available power:
• Four green bars—Indicates a full charge.
• Three green bars—One quarter of the battery power has been used.
• Two yellow bars—One half of the battery power has been used.
• One red bar—Three quarters of the battery power has been used. Once the battery has reached
5% of its total battery power, a low battery warning displays.
While the Li-Ion battery is charging, the battery indicator graphic is animated and the word “Battery”
is replaced with “Charging.” Once the battery is fully charged, the battery indicator graphic displays
four static green bars and the word “Charging” is replaced with “External” until the charging cable
is removed.
To Disable GPS
There are many features on the Earthmate GPS PN-20 that do not require a GPS fix. You can turn off
the GPS connection using the Disable GPS option in the Satellites menu.
1. From the Satellites Page, press MENU.
2. Use the arrow keypad to highlight Disable GPS.

Note: WAAS was developed
by the Federal Aviation Administration to enhance the accuracy—usually to within three
meters of actual position—of
GPS receivers by providing
a modified GPS signal. After
calculating the error factor
at ground control stations
throughout the U.S., the corrected signal is transmitted to
two geostationary satellites
that in turn transmit the GPS
signal back to Earth.

We Bring Technology Down to Earth™
Since its incorporation in 1976, DeLorme has developed an unprecedented reputation as a leader in the mapping industry. From early beginnings as a paper
atlas publisher, the company quickly emerged as a pioneering technological innovator. DeLorme not only embraced new technologies, it developed them.
In the mid-1990s, before GPS usage was widespread, DeLorme was pioneering laptop GPS solutions that today include the popular Earthmate GPS LT-20.
Subsequent development led to industry-first GPS solutions for Pocket PC and Palm OS devices and more recently for Bluetooth GPS solutions.
