VI - PRINCIPLE OF TIME SETTING
6.1 NTP receivers
1. When they are fi rst 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 reconfi guration 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 fl ashes every
second and the clock continues autonomously.
In NTP mode, if the synchronisation is not correct after 24 hours, the clock pictogram will
fl ash every 5 seconds; the display goes black with the two fi xed 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 fi xed 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.
6.2 Annex for time difference
