VI - PRINCIPLE OF TIME SETTING

6.1 NTP receivers

1.
When they are first switched on, the time is initialized at 00:00:00 on 01/01/2000.
The clock attempts to synchronise on switching on, after each manual time change, or
after a reset or reconfiguration of the clock; as soon as three consecutive coherent
messages have been received, it adjusts its time base.
The time displayed takes into account the time differences chosen in the time menu (time
differences and seasonal changes).
If there is no NTP message for more than one hour, the clock pictogram flashes every
second and the clock continues autonomously.
In NTP mode, if the synchronisation is not correct after 24 hours, the clock pictogram will
flash every 5 seconds; the display goes black with the two fixed dots.
In NTPI mode, if the synchronisation is not correct after 24 hours, the clock continues to
function on its internal quartz crystal with the two fixed dots.
Caution: if a time change is made on the master clock after synchronisation, the
correction will be made only after reception of three coherent messages.
