What Is Navi@Mouse?
Congratulations on your purchase of Navi@Mouse, a GPS (Global Positioning System) receiver for
a variety of applications. Navi@Mouse incorporates the latest GPS technology from the leading GPS
receiver manufacturer.
By connecting it to a notebook PC with the map or navigation software, Navi@Mouse helps you
locate places and points of interest, conduct personal & vehicle navigation, or conduct geographical
survey activity.
What Have Inside the Package?
Before you start up, make sure your package includes the following items. If any item is missing or
damaged, contact your dealer immediately. Please refer to the contact information on the last page of this
manual.
◆ GPS Receiver ◆ Application CD
◆ Cable for RS232 or USB (depending on what you buy

What Is GPS ?
In 1974 the USA Department of Defense started development of the Global Positioning System
(GPS), a constellation of 24 satellites that orbit 12,000 miles above the Earth. By triangulating the signals
from four of the satellites, a receiving unit on Earth can pinpoint its current location to within a few
meters. A GPS device receives the data from satellites and then converts the longitude, latitude, and
altitude (LLA) data into a location point. Position and navigation information is vital to a wide range of
professional and recreational activities including surveying, search and rescue, tracking, hiking,
navigating, and so forth.

Troubleshooting
Problem Reason Solution
Test fail Poor connection Check the RS232 and PS2 connector or USB connector to
make sure they are well connected.
Wrong BIOS setting
for PS2
Check the BIOS setting to make sure the PS2 port is enable.
If you still get the testing fail message, contact your local
distributor.
Open com port fail All the serial COM
port have been used
for other application
program
Close all the other application programs and rerun the
Navi@Mouse Testing program.
There is nothing
showing on the
tracking diagram
even if the test
result is success.
Navi@Mouse can
not receive the GPS
signal on the testing
area.
Move Navi@Mouse to somewhere there is exposed to
outdoors.
Note: normally we cannot receive the GPS signal indoors.
No position output
but timer is
counting
1.Weak or no GPS
signal can be
received at the place
Navi@Mouse are.
2.At outdoor space
but GPS signal is
block by buildings
Go outdoor place without high building to block the signal
and retest the Navi@Mouse again.
