Acquiring position and navigating
Notes on acquisition time of the device*
(1) Long press the
“power button” for 3s to turn on the device.
(2) In a relatively open outdoor environment, point the device reception
antenna to the sky. Wait for several minutes until the position is fixed.
(The
“GPS LED” flashes after the position is fixed)
(3) Pair and establish connection with the terminal as instructed in
previous pages.
(4) Launch the navigation software. Configure the COM port and set the
baud rate to 38,400. When the
“Bluetooth LED” becomes always on,
the connection is established and navigation begins.
There are three kinds of GPS acquisition at startup: cold start, warm start,
and hot start.
(1) Cold start: 35s
A cold start is the startup in any of the following situations: the device
is used for the first time; ephemeris is lost due to low battery level; or
the device has been moved for more than 1,000km when it is turned
off.
(2) Warm start: 32s
A warm start is the startup in two or more hours after the last
positioning.
(3) Hot start: 1s
A hot start is the startup within two hours after the last positioning.
*The test environment is a place with relatively open view to the sky.
If it is difficult for the device to fix the position and the GPS LED is always
on, you should point upward the antenna part of the device and wait for a
while. If the position still cannot be fixed after 5 minutes, perhaps you are
situated at a place where GPS signals cannot reach. In such a case, move to
a place as open as possible and try to fix the position once again.

Point upward the GPS
reception antenna to help
receive satellite signals.
It is not recommended for the
receiver to fix the position for the
first time at an indoor window or
any other relatively enclosed
environment.
