Having set the date for the start of the winter period, press [SEL], the
time difference in relation to UTC time flashes. The time difference is
adjusted by pressing [+].
The value to choose is between -12 h 30 and +12 h 30 by increments of 0 h 30.
N.B. : for independent clocks (without external synchronisation), this adjustment is
inactive. The time is adjusted only via the time setting menu.
The summer/winter or winter/summer time changeover is carried out at 2am local time on the

VI - PRINCIPLE OF TIME SETTING
6.1 Afnor receiver model
1. On the initial powering up, the time is initialised at 00h00mn00ss on 01/01/2000.
After a powering up, a time setting, a reset or a new configuration, the clock search to be
synchronised. Since 3 consecutive correct messages have been received, it set up its time
base to the correct time. After, it is automatically done each hour.
Between 2 synchronisation, the time base bring forward according to the internal base.
If the clock is in mode COD
6
, the time displayed is the time received.
If the clock is in mode LOC
7
, the time displayed depend on the offset selected in the Time
mode menu (Seasonal change and offset change).
Caution: if the current time of the master clock is modified after the synchronisation of the
slave clocks, the correction will be achieved the next hour.
2. If the synchronisation is not correct after 20 seconds, a new time code search is made the
following minute.
If the synchronisation is not correct after 24 hours, the clock pictogram will flash every 5
seconds, the display disappeared with only the 2 dots fixed.
If the AFNOR synchronisation is not correct after 1 hour, the clock pictogram flashes every
second and the clock keeps on working on its own time basis.
In AFNOR mode, if the synchronisation is not correct after 24 hours, the clock pictogram
flashes every 5 seconds and the display disappears with only the 2 dots fixed.
In AFNORI mode, if the synchronisation is not correct after 24 hours, the clock keeps on
working on its own time basis with the 2 dots fixed.
Nota : On an Irig-B network, year must be manually entered by the user.

The last day is either 28, 30 or 31 depending on the month (28 is
imposed for the month of February whatever the year).
