WHAT TO DO IF...?
… CHECK.
■ The clock displays
.
■ The clock detects the “low battery
”,
threshold, the pictogram representing an empty battery appears
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 does not display the day
of the week but a number
.
■ The clock is programmed in week number or day number display
mode (reread the note on page
27, § 4 ).
■ The clock display does not go
beyond 12 hrs
.
■ The clock is programmed in 12 hr instead of 24 hr mode (reread the
note on page
26, § 2 ).
■ The time synchronisation of the
clock is correct, but the time change
has not taken place, the date or the
time is not correct.
.
■ Check in time change mode that the clock is correctly programmed
(reread the note on page
28, § 5).
■ The radio pictogram flashes once
every 5 seconds.
■ No radio reception, move the clock.
.
■ The display has disappeared, only
the 2 dots are flashing.
■ You are in “Eco” mode between 11pm and 6am.
.
■ No display of time, only fixed colon
mark
.
■ The DHF clock has received no time message for more than 24
hours, check the DHF transmitter operation.
■ The display is completely blank.
■ The batteries are completely discharged, replace them.
■ Incorrect year on an Irig-B network.
■ Year must be manually entered on an Irig-B network.
■ no synchronisation after the
installation.
.
■ 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.
■ Irig-B / AFNOR clocks not on time
after a time setting on the master
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.
■ A receiver clock on a ½ minute
network is 30s alter after the
installation.
■ 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.
■ Minute or ½ minute receiver with
fixed display of time and 2 dots.
■ no impulse, check the master clock and the network.
■ AFNOR or Irig-B receiver with no
display of time, the 2 dots fixed and the
clock pictogram flashing.
no time coded message for more than 24 H. Check the master clock
and the network.
