Reset • Open the GNSS Toolbox and tap on Reset. A message then
asks you if you want to reset the receiver now. Use this
option only if you think the receiver is not working
properly.
Using this function results in a cold reset of the receiver.
Through a cold reset, all the GNSS settings, including
almanac data, are cleared making it necessary for you to
restore each of them manually. A few minutes are needed
after a cold reset before the receiver is back to work.
Using the Reset function is recommended when only the
GNSS Toolbox (and not other field software) is running on
the platform.
About This function provides the software version of GNSS Toolbox,
followed by the Spectra Precision legal line.
