WHAT TO DO IF...?
■ The clock does not display the
day of the week but a number.
■ The clock display does not go
beyond 12 hrs.
■ The time synchronisation of the
clock is correct, but the time
change has not taken place, the
date or the time is not correct..
■ The radio pictogram flashes
once every 5 seconds.
■ The display has disappeared,
only the 2 dots are flashing.
■ No display of time, only fixed
colon mark.
■ The display is completely blank. ■ Lack of mains, restore it..
■ Incorrect year on an Irig-B
network.
■ no synchronisation after the
installation..
■ Irig-B / AFNOR clocks not on
time after a time setting on the
master clock.
■ A receiver clock on a ½ minute
network is 30s alter after the
installation.
■ Minute or ½ minute receiver
with fixed display of time and
2 dots.
■ AFNOR or Irig-B receiver with
no display of time, the 2 dots
fixed and the clock pictogram
flashing.

...CHECK.
■ The clock is programmed in week number or day number
display mode (reread the note on page 27, § 4 ).
■ The clock is programmed in 12 hr instead of 24 hr mode
(reread the note on page 26, § 2 ).
■ Check in time change mode that the clock is correctly
programmed (reread the note on page 28, § 5).
■ No radio reception, move the clock..
■ You are in "Eco" mode between 11pm and 6am..
■ The DHF clock has received no time message for more
than 24 hours, check the DHF transmitter operation.
■ Year must be manually entered on an Irig-B network.
■ Check that the type of signal sent by the master clock (min,
½ min, AFNOR or Irig-B) is in accordance with the type
programmed in the clock.
■ 1) wait the hour stroke on the slave clock so that it search
to be synchronised,
■ 2) change manually the time of the clock, so that it will
have to do an immediate search of AFNOR or Irig-B
synchronisation.
■ It is impossible for a slave clock to discern between two
1/2 minute impulses which one is the master clock minute
stroke, the reversal of the two wires is needed to correct
the time.
■ no impulse, check the master clock and the network.
■ no time coded message for more than 24 H. Check the
master clock and the network.
