System accuracy
Accuracy of GPS satellites
The unit positions automatically when the unit receives the signals from 3
or more GPS satellites. An error margin of ± 10 meters is typical, but
possibly as much as two or three hundred meters, depending on
circumstances. In this case, the current symbol will differ from the actual
current location. For the same reason, the current direction indicated on the
personal computer may differ from the actual current location.
If you use the unit away from the place where you last used it, such
discrepancies may occur.
Differences when receiving signal
Positioning information accuracy may vary depending on the GPS system,
environment or time. In this case, even if you follow the proper procedures,
positioning information may not be accurate, but this is not a malfunction.
