WARNING!
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE
METHOD TO OBTAIN POSITION INFORMATION. ALWAYS
MAKE SURE TO BRING A MAP AND A SILVA COMPASS AS
A BACK-UP!
CAUTION
When showing navigation data to a position (waypoint), a GPS
unit will show the shortest, most direct path to the waypoint. It
provides navigation data to the waypoint regardless of
obstructions. Therefore, the prudent navigator will not only take
advantage of all available navigation tools when traveling to a
waypoint, but will also visually check to make sure a clear, safe
path to the waypoint is always available.
WARNING!
When a GPS unit is used in a vehicle, the vehicle operator is
solely responsible for operating the vehicle in a safe manner.
Vehicle operators must maintain full surveillance of all
pertinent driving, boating or flying conditions at all times. An
accident or collision resulting in damage to property,
personal injury or death could occur if the operator of a GPS-
equipped vehicle fails to pay full attention to travel
conditions and vehicle operation while the vehicle is in
motion.

Section 1: Read Me First!
How this manual can get you out on the road, fast!
Welcome to the exciting world of GPS! We know you're anxious to begin
navigating, but we have a favor to ask. Before you grab the batteries and head
outside, please give us a moment or two to explain how our manual can help
you get the best performance from this remarkable little GPS unit.
First, we want to thank you for buying an Atlas. Whether you're a first time
user or a professional navigator, you'll discover that the Atlas is a true pocket-
sized, full-featured mapping GPS receiver. When you team an Atlas with one of
our specialized MapCards™ you have an incredible combination. No other
consumer GPS mapping system on the market offers so much information and
so many features in one package.
Our goal for this book is to get you on the road or out to the woods and water
fast, with a minimum of fuss. Like you, we'd rather spend more time traveling,
in the woods or on the water, and less time reading the manual!
So, we designed our book so that you don't have to read the whole thing from
front to back for the information you want. At the start (or end) of each
segment, we'll tell you what content is coming up next. If it's a concept you're
already familiar with, we'll show you how and where to skip ahead for the next
important topic. We've also made it easy to look up any tips you may need from
time to time. Here's how:
The manual is organized into six sections.
Section 1 is an introduction to the Atlas and to GPS. It tells you the basics you
need to know before you can make Atlas look around and tell you where you
are.
Section 2 will help you get the batteries and MultiMedia Card (MMC) correctly
installed in your Atlas. We'll also tell you about some of the accessories
available for your unit.
Section 3 is the heart of our book, Easy Mode Operation. It will introduce you to
the basic GPS functions. We lead off this section with a one-page Easy Mode
Quick Reference. (If you've already figured out how to load the batteries
yourself, and you just can't wait any longer, turn to the Quick Reference
on page 29 and head outside with your Atlas!)
The rest of Section 3 contains short, easy-to-scan lessons that follow one
another in chronological order. They're all you'll need to know to get on the
road quickly.
Easy Mode operation will meet the navigation needs of many users. But, after
you've learned the basics (or if you already have some GPS experience), you

9
may want to try out some of Atlas's many advanced features. That brings us to
Section Four, Advanced Mode Operation. After we introduce the Advanced
Mode menus and submenus, the rest of the section contains all of Atlas's
command functions, organized in alphabetical order.
When you come to a menu command on the Atlas screen, you can look it up in the
manual by skimming over the table of contents, just flipping through Section 3 or
scanning through the command portion of Section 4.
Atlas is ready to use right out of the box, but you can fine tune and customize
the operation with dozens of options. We describe how to use them in Section
5, System Setup and GPS Setup Options. This section covers both Easy Mode
and Advanced Mode options.
Finally, in Section 6, we go into more detail on one of Atlas's most remarkable
capabilities — Searching. We'll introduce a couple of search examples in both
the Easy and Advanced mode sections, but there are so many map items you
can search for, we had to give this function it's own section in the manual! For
example, did you know Atlas can look up business phone numbers, functioning
as a virtual Yellow Pages? We’ll show you how in Section 6.
Now, if you're into the fine details, glance over the next segment on
specifications to see just how much GPS power you hold in your hand. It's
important to us but, if you don't care how many waypoints Atlas can store or
how long the batteries last, skip ahead to important information on how Atlas
works, on page 10.
Note! All references in this manual are made in English, which is the default
setting of the Atlas’s operative system. You can select other languages in the
MENU when in “Advanced Mode”.

How Atlas Works
You'll navigate faster and easier if you understand how Atlas scans the sky to
tell you where you are on the earth — and, where you're going. (But if you
already have a working understanding of GPS receivers and the GPS
navigation system, skip ahead to Section 2, Installation & Accessories. If you're
new to GPS, read on, and you can later impress your friends with your new-
found knowledge.)
First, think of your Atlas as a small but powerful computer. (But don't worry —
we made Atlas so easy to use, you don't need to be a computer expert to find
your way!) The unit includes a keypad and a screen with menus so you can tell
Atlas what to do. The screen also lets Atlas show your location on a moving
map, as well as point the way to your destination.
This pocket-sized microprocessor also contains an antenna and specialized
scanning receiver, something like your car radio. But instead of your favorite
dance tunes, this receiver tunes in to a couple of dozen GPS satellites circling
the earth.
Atlas listens to signals from as many satellites as it can "see" above the
horizon, eliminates the weakest signals and then computes its location in
relation to those satellites. Once Atlas figures its latitude and longitude, it plots
that position on the map shown on the screen. The whole process takes place
several times a second!
The magic doesn't stop there. Stored in the permanent memory of each Atlas is
a basic background map of the entire world. (For just what's in the map, see
the following segment on different Atlas models.) We lock it in here at the
factory — you can't change or erase this map.
Another portion of Atlas's onboard memory is devoted to recording GPS
navigation information, which includes waypoints, event marker icons, trails and
routes. This lets you look back the way you came. Think of this data storage
like the hard drive memory in a computer or a tape in a cassette tape recorder.
You can save several different GPS data files, erase them and record new
ones, over and over and over again. Like any computer file, these GPS Data
Files (file format *.usr) can be shared between Atlas and other GPS units, or
personal computers.
Atlas has one more thing in common with a personal computer. Just as
computers have a floppy disk drive for storing and exchanging files, Atlas has a
slot for an MMC (MultiMedia Card) or SDC (Secure Digital Card) flash memory
card. These solid-state memory devices are about the size of a postage stamp,

12
but can hold data ranging from 8 MB to 256 MB in size. (Compare that to a
floppy disk's 1.44 MB capacity!) Atlas uses all that MMC space for two key
purposes.
First, you can backup your onboard GPS Data Files by copying them to the
MMC. Since the MMC is removable (like a floppy disk or a cassette tape), you
can store these GPS Data Files on a personal computer equipped with an
MMC card reader. (Or store them on a pocketful of MMCs, if you don't have a
computer.) (NOTE: No matter where they come from, GPS Data Files must be
loaded from the MMC into memory before Atlas can use them.)
The other key use for MMCs is storage of special high-detail, custom maps
containing much greater detail than the basic background map. These Custom
Map Files (file format *.lcm) can also be shared between Atlas units and
personal computers.
Atlas automatically reads Custom Map Files directly from the pre-loaded MMC
MapCards. To use a custom map, all you need to do is slide an MMC
containing a map into the unit.
Atlas
The Atlas is perfect for precise personal navigation right out of the box. It
comes loaded with the basic built-in custom Silva background map. This
background map includes: low-detail maps of the whole world (containing
cities, major lakes, major rivers, political boundaries); and medium-detail maps
of the United States (containing all incorporated cities; Interstate, U.S. and
state highways; Interstate highway exits and exit services information; large-
and medium-sized lakes and streams.)
It is MMC-capable, but a card is not included in the package. NOTE: This unit
can search for waypoints, map places and highway exits (US only). It also
offers exit services information (US only), but no Point of Interest (POI)
information is included. POI information is available in MapCreate maps.
Please contact your local dealer for information/purchase.
Introduction to GPS and WAAS
Well, now you know the basics of how Atlas does its work. You might be ready
to jump ahead to Section 2, Installation & Accessories, so you can install the
batteries. Or, you might want to see how our text formatting makes the manual
tutorials easy to skim. If that's the case, refer to "How to Use This Manual". But,
if you want to understand the current state of satellite navigation, look over this
segment describing how GPS and its new companion WAAS work together to
get you where you're going.
The Global Positioning System (GPS) was launched July 17, 1995 by the

13
United States Department of Defense. It was designed as a 24-hour-a-day,
365-days-a-year, all weather global navigation system for the armed forces of
the U.S. and its allies. Civilian use was also available at first, but it was less
accurate because the military scrambled the signal somewhat, using a process
called Selective Availability (SA).
GPS proved so useful for civilian navigation that the Federal Government
discontinued SA on May 2, 2000, after the military developed other methods to
deny GPS service to enemy forces. Reliable accuracy for civilian users jumped
from 100 meters (330 feet) under SA to the present level of 10 to 20 meters
(about 30 to 60 feet.)
Twenty-four satellites orbit 10,900 nautical miles above the Earth, passing
overhead twice daily. A series of ground stations (with precisely surveyed
locations) controls the satellites and monitors their exact locations in the sky.
Each satellite broadcasts a low-power signal that identifies the satellite and its
position above the earth. Three of these satellites are spares, unused until
needed. The rest virtually guarantee that at least four satellites are in view
nearly anywhere on Earth at all times.
A minimum of three satellites are required to determine a 2D fix.
The system requires signal reception from 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.) This
is 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 signals, GPS works at very high
frequencies. These signals can be easily blocked by trees, buildings, an
automobile roof, and even your body.
Like most GPS receivers, Atlas doesn’t have a magnetic 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. Therefore, in order for Atlas 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 or trolling speeds — it will. There will simply be more
"wandering" of the data shown on the display.
WAAS (Note! Only working in the U.S.)
GPS is plenty accurate for route navigation, but the U.S. Federal Aviation
Administration has special needs for aircraft traffic control that go beyond basic
GPS. The FAA has a plan under way to boost GPS performance even further
with its Wide Area Augmentation System, or WAAS. This GPS add-on will
include a time control element that will help airliners fly closer together while
avoiding collisions. In addition to carefully spacing airplanes along travel

14
corridors, WAAS will eventually make instrument landings and takeoffs more
accurate as it replaces existing aviation navigation systems.
Non-aviators can use WAAS signals to make their GPS navigation even more
accurate. Your Atlas receives both GPS and WAAS signals. However, WAAS
has some limits you should know about.
First, the U.S. government has not completed construction of the WAAS
system, so it is not yet fully operational. The ground stations are in place, but
only a few of the needed WAAS satellites have been launched.
WAAS can boost the accuracy of land GPS navigation, but the system is
designed for aircraft. The satellites are in a fixed orbit around the Equator, so
they appear very low in the sky to someone on the ground in North America.
Aircraft and vessels on open water can get consistently good WAAS reception,
but terrain, foliage or even large man-made structures frequently block the
WAAS signal from ground receivers.
You'll find that using your GPS receiver without WAAS 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 map or chart and a compass.
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 destination,
for example. It’s up to you to safely navigate around obstacles, no matter how
you’re using this product.

How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow
"keystrokes" appear as boldface type. So, if you're in a hurry (or just need a
reminder), you can skim the instructions and pick out what menu command to
use by finding the boldface command text. The paragraphs below explain how
to interpret the text formatting for those commands and other instructions:
Arrow Keys
The arrow keys control the movement of dotted cross-hair lines on your
mapping screen called the cursor. The arrow keys also help you move around
the Atlas menus so you can execute different commands. They are
represented by symbols like these, which denotes the down arrow key, the up
arrow, the left arrow and the right arrow: ↓↑←→.
Keyboard
The other keys perform a variety of functions. When the text refers to a key to
press, the key is shown in bold, type. For example, the "Enter/Save" key is
shown as ENT and the "Menu" key is shown as MENU.
Menu Commands
A menu command or a menu option will appear in small capital letters, like this:
ADVANCED MODE. These indicate that you are to select this command or option
from a menu or take an action of some kind with the menu item. Texts that you
may need to enter or file names you need to select are show in italic type, such
as trail name.
Instructions = Menu Sequences
Most functions you perform with Atlas are described as a sequence of
keystrokes and selecting menu commands. We've written them in a condensed
manner for quick and easy reading.
For example, instructions for backtracking a trail in Easy Mode would look like
this:
1. Press MENU|↓to NAVIGATE TRAIL|ENT.
2. Now, begin moving and follow your Atlas.
Translated into complete English, step 1 means: "Press the Menu key. Next,
press the down arrow key to scroll down the menu and select (highlight) the
Navigate Trail menu command. Finally, press the Enter key.

16
Section 2: Installation & Accessories
Power
The Atlas operates from AA batteries or on 3 volts DC using an optional
external power cable with a cigarette lighter adapter. If the power cable is used,
the Atlas automatically switches to it if the external power is greater than the
battery voltage. If the external power fails, the unit automatically switches to the
batteries. An internal lithium battery keeps your stored data safe and accessible
for as long as 10 years.
Batteries
The unit requires two, 1.5 volt AA batteries. We recommend that you use
alkaline batteries for the best trade-off between battery life and cost. You can
also use rechargeable AA alkaline batteries or rechargeable AA nickel metal
hydride (NiMH) batteries. Rechargeable alkaline batteries will not last as long
as standard alkaline batteries.
Do not mix different battery types. Mixing battery types may cause leakage.
(For example, don’t use both alkaline and NiMH batteries at the same time, and
don't use standard alkalines with rechargeable alkalines.)
Battery Installation
Turn the unit over so that the back is facing you. Place your thumb on the large
arrowhead on the battery compartment cover. Press in and down, toward the
bottom of the unit (in the direction indicated by the arrow.) The battery cover
will snap off.
Remove Atlas battery cover.
Install the batteries according to the decal in the battery compartment, which
shows the correct polarity. Point the positive pole of the upper battery to the
left; point the positive pole of the bottom battery to the right.
Replace the battery compartment cover. Align the cover latch tab with the slot
inside the case. With a finger, press the bottom of the cover in and then up,
toward the top of the unit
Replace battery compartment cover. Align
tab with slot, left. Press in cover bottom, right

17
Cigarette Lighter Power Adapter (Optional Accessory art.no.
22608)
To use external DC power: Plug the power cable's cigarette lighter adapter into
a cigarette lighter receptacle. Next, slide the other connector over the power
contacts on the bottom of the Atlas case.
Attach external power cable to Atlas.
MMC or SDC Memory Card Installation
Your Atlas uses a MultiMedia Card (MMC) to store information, such as
waypoints and other GPS data. The unit can also use Secure Digital Cards (SD
card or SDC) to store information.
NOTE:
Throughout this manual, we will use the term MMC, but just remember that
your unit can use an MMC or SDC to store data.
MMC cards with mapping data are available from Silva; see www.silva.se for
more information. Blank MMC and SD cards are also available at many
consumer electronics stores.
The MMC slot is located in the battery compartment, behind the batteries on
the right side of the unit. The battery compartment decal points out the slot,
which is also marked by small white letters on the circuit board.
To remove an MMC
1. Remove battery compartment cover.
2. Remove batteries, if present.
3. Hold unit upright in one hand. Use a thumbnail or fingernail to grab the
groove in the bottom of the MMC.
4. Drag the MMC from the slot into the battery compartment.
5. Hold Atlas face up and give it a shake to dump the MMC into your hand or
onto a work surface.
To add an MMC or SDC
1. Remove battery compartment cover.
2. Remove batteries, if present.
3. Hold unit upside down in one hand. Grasp the bottom corner of the MMC
with your other hand. The MMC label should be toward you.

18
4. Use the white lines and text on the circuit board as a guide and drop the
MMC into the slot.
5. Gently shake the unit or use your finger to nudge the MMC into vertical
alignment. Then, gently push the card into the slot with your finger.
6. Replace the batteries and battery cover.

19
External Antenna (Optional accessory art.no. 22607)
A GPS antenna requires a clear view of the sky for optimum reception. Inside a
vehicle, your Atlas can sometimes maintain “satellite lock” while sitting on the
seat beside you, but we don't recommend this for optimum performance.
Since fewer satellites are "visible" through the vehicle roof, this operating mode
will reduce position accuracy and increases the chance of losing satellite lock.
Inside a vehicle, the unit operates best with an optional external antenna
mounted on the windshield, on the dash or on the top of the vehicle.
The external antenna includes a magnetic base that allows temporary mounting
on any flat ferrous metal surface. A suction-cup mount allows you to attach the
antenna to a windshield.
Attach Atlas antenna to windshield bracket with two screws.
You may achieve good results by simply placing the external antenna on the
top of the dash, at the base of the windshield.
To use the antenna: Mount it in a location with an unobstructed view of the sky.
Plug the connector into the unit's antenna socket, located on the back, in the
