Smart Re-Aiding causes the MC9500-K to reconnect to the SUPL server and download new A-GPS data if there
are satellites in view and the number of satellites in use fall below the SVLimit value and the length of time passed
since the last SUPL session is more than the value set in the Interval field.
Timing Control on Opening determines whether a SUPL session is established when the GPS port is opened. If
the length of time passed since the last successful SUPL session is less than the set interval, a SUPL session is
not established when the GPS port is opened.
Tap the Factory Reset button to perform a factory reset on the GPS chip.
