WHAT TO DO IF...?
■ The clock displays .
■ 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.
■ The display is completely blank.
■ 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.
■ Incorrect year on an Irig-B network. ■ Year must be manually entered on an Irig-B network.
■ 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.
■ No display of time, only fixed colon
mark.

...CHECK.
■ The clock detects the "low battery" threshold,
the pictogram representing an empty battery appears
as a fixed display for 5 days. After this period, it flashes
until the display disappears completely (batteries have
run out). Replace the batteries. Resetting of the time
and date is, automatic for radio synchronised or Irig-B
/ AFNOR clocks, manual for independent and receiver
clocks. Dust on the battery contact terminals (+ and -)
can disrupt the power supply to the clock. Clean these
contact terminals with a soft dry cloth, if necessary.
■ The clock is programmed in week number or day
number display mode (reread the note on page 33,
§ 5 ).
■ The clock is programmed in 12 hr instead of 24 hr
mode (reread the note on page 34, § 2 ).
■ Check in time change mode that the clock is correctly
programmed (reread the note on page 35, § 6).
■ No radio reception, move the clock.
■ You are in "Eco" mode.
■ The batteries are completely discharged, replace them.
■ 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.
■ lack of impulse, check the master clock and the
network.
■ Lack of time coded message since more of 24 H.
Check the master clock and the network.
■ The DHF clock has received no time message for
more than 24 hours, check the DHF transmitter
operation.
