Spectracom SecureSync User Manual

In new SecureSync units, per default both GPS, and Galileo are enabled. Either selection can
be disabled, but not both of them (if both are turned off, no changes will be saved and the last
constellation setting will be preserved).
To verify if satellite signals for the selected GNSS constellations are currently received, see
"Determining Which GNSS Satellites Are Received" on the facing page.
