BLANK ON GPS UNLOCK. Use the left (◄) or right (►) arrow button to turn ON
or OFF the blanking function on the BLACK 2 output when a loss of lock to the
GPS/GLONASS signal is detected. When turned on, the BLACK 2 output will be
blanked as long as the loss of lock condition occurs. This purpose of this function
is to trigger a change-over. If configured to blank on loss of lock, this output
should not be used for normal reference applications.
NOTE. This submenu is available only when BLACK 2 is the selected output.
