CAUTION!
The Global Positioning System (GPS) is operated by the government of the United States, which is solely
responsible for its accuracy and maintenance. The system is subject to changes which could affect the accuracy and
performance of all GPS equipment. Although the GPS II is a precision electronic NAVigation AID (NAVAID), any
NAVAID can be misused or misinterpreted and, therefore, become unsafe.
WARNING
For vehicular applications, it is the sole responsibility of the owner/operator of the GPS II to secure the GPS unit
so that it will not cause damage or personal injury in the event of an accident. Do not mount the GPS II over airbag
panels or in a place where the driver or passengers are likely to have an impact with it in an accident or collision. The
mounting hardware provided by GARMIN is not warranted against collision damage or the consequences thereof.
WARNING
For vehicular operations, it is the sole responsibility of the operator of the vehicle to operate his or her vehicle in
a safe manner, maintain full surveillance of all driving conditions at all times, and never become distracted by the GPS
II to the exclusion of safe operating practices. It is unsafe to operate the GPS II while you are driving. Failure by the
operator of a vehicle equipped with a GPS II to pay full attention to operating the vehicle and road conditions while the
vehicle is in motion could result in an accident or collision with property damage and personal injury.
CAUTION!

What is GPS?
GPS is a system of 24 satellites which circle the earth twice a day in a very pre-
cise orbit and transmit information to earth. The GPS II must continuously “see” at
least three of these satellites to calculate your position and track your movement.
By using an almanac (a timetable of satellite numbers and their orbits) stored in
the receiver’s memory, the GPS II can determine the distance and position of any
GPS satellite and use this information to compute your position.
Your GPS receiver can only see satellites above the horizon, so it needs to know
what satellites to look for at any given time. To use this almanac data, your GPS
needs to either be told its general location or given the opportunity to find itself, or
“initialize.” Once you initialize the unit to a position, it will usually compute a fix
within a few minutes.
Initialization is only necessary under the following conditions:
• The first time you use your GPS II (from the factory).
•After the GPS II has been moved over 500 miles from the last time you
used it (with the power off).
•If the GPS II’s memory has been cleared and all stored data has been lost.

Satellite Signals
Because the GPS II relies on satellite signals to provide you with navigation guid-
ance, the receiver needs to have an unobstructed, clear view of the sky for best per-
formance. In a nutshell, the GPS receiver’s view of the sky will generally determine
how fast you get a position fix— or if you get a fix at all. GPS signals are relatively
weak and do not travel through rocks, buildings, people, metal, or heavy tree cover,
so remember to keep a clear view of the sky at all times for best performance.
Once the GPS II has calculated a position fix, you’ll usually have anywhere from
four to eight satellites in view. The GPS II will then continuously select the best satel-
lites in view to update your position. If some of the satellites in view get blocked or
“shaded,” the receiver can simply use an alternate satellite to maintain the position
fix. Although a GPS receiver needs four satellites to provide a three-dimensional (3D)
fix, the GPS II can maintain a two-dimensional (2D) fix with only three satellites. A
three-dimensional fix means the unit knows its latitude, longitude, and altitude,
while a two-dimensional fix means the unit knows only its latitude and longitude.
To prevent accidental battery
power loss, the GPS II will
automatically shut off 10 min-
utes after the last keystroke if
the unit is not tracking at least
one satellite and has never
acquired a position fix.
