							Cautions
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.
For vehicular applications, itÕs 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.
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 operat-
ing the vehicle and road conditions while the vehicle is in motion could result in an accident or collision with
property damage and personal injury.

							What is GPS?

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 ÒseeÓ 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 receiverÕs 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
Òinitialize.Ó Once you initialize the unit to a position, it will usually compute a fix
within a few minutes. WeÕll show you how to initialize your new GPS on p. 7.
Initialization is only necessary under the following conditions:
¥ The first time you use your receiver (from the factory).
¥ After the receiver has been moved over 500 miles from the last time you
used it (with the power off).
¥ If the receiverÕs memory has been cleared and all stored data has been lost.

Satellite Acquisition
Satellite Acquisition
Because the GPS II
+relies on satellite signals to provide you with navigation
guidance, the receiver needs to have an unobstructed, clear view of the sky for best
performance. In a nutshell, the GPS receiverÕs view of the sky will generally deter-
mine how fast you get a position fixÑor if you get a fix at all. GPS signals are rela-
tively 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, youÕll usually have anywhere from
four to twelve satellites in view. The receiver will then continuously select the best
satellites in view to update your position. If some of the satellites in view get blocked
or Òshaded,Ó 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, it 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 not
acquired a position fix.

Battery Installation
Battery Installation
The GPS II
+operates on 4 AA batteries (not included), which are installed at the
base of the unit. These batteries provide up to 24 hours of use.
To install the batteries:
1. Flip up the metal ring at the base of the unit, and turn the ring 90û counter clockwise.
2. Install the batteries (Fig. 3), and close the battery compartment door.
3. Lock the door in the closed position by rotating the metal ring 90û clockwise.
Battery life varies due to a variety of factors, including temperature and
backlighting. You may find that the battery life varies in different conditions and
that lithium batteries provide longer life in colder conditions.
When replacing the GPS II
+Õs batteries, observe the polarity markings
engraved in the plastic case. An internal 10-year lithium battery will retain your
data while youÕre changing batteries.
