General tips for GPS application
The following content is tips for GPS device application and
operation. Please read it before starting use of the GPS device,
so that you may make a better use of the GPS device.
While the GPS device is working, it receives signal from satellites for
positioning. The signal from satellite may not be received, or be
weakened in room, nearby some big buildings, or under overhead
bridges.
When the GPS device is receiving satellite signals, you will get signals
from different satellites when you are in different places, this is called
"Satellite Path", a "Satellite Path" only covers a range of 300 KM. If a
"Satellite Path" is defined at place A, then turn off the device and move
to another place beyond 300 KM away from A, the device is under
another "Satellite Path", At this moment, the device needs to search
for satellite signal again. To track the new "Satellite Path", this will
take quite a long time. To save time for this searching, you may click
"GPS Reset" button in menu of "GPS Testing" to clear the previous
“
Satellite Path".
It will be difficult and taking more time to catch positioning signal from
satellite during high speed driving. It is suggested to search the
positioning signal by stopping your car for a better and safer effect.
While charging the device, please only use the travel charger or car
charger equipped by the manufacturer in its original package. Other
chargers may cause damage to this device, and this damage is not
covered by our warranty.
