Sys. update: If this option is chosen, the time written in the display
is updated using only the internal circuitry of the RTU itself. Conse-
quently, if your Iridium system is turned off and the on again, the
clock will be reset to a default time. The correct time must then be
set again manually each time.
GPS update: If this option is chosen, the time written in the display
is updated using the connected GPS, if any. Consequently, even if
your Iridium system is turned off and then on again, the clock will still
be adjusted to the correct time each time a GPS update is received.
If no GPS is available, it makes no sense choosing this option.
