Note: When pressing the   button the next ON or OFF marker may start to flash. 
This indicates you have tried to set a time equal to one of the next programme times 
already in the memory.  Similarly, when pressing the   button the previous ON or 
OFF marker may start to flash. This indicates you have tried to set a time equal to 
one of the previous programme times. If this happens the ST9400C simply moves 
both times together as long as you continue to press the     or   buttons.  Follow 
the procedure in ‘Reviewing the Programme Times’ (page 7) to check and adjust 
these times as necessary.
c. 
‘SET OFF-TIME 1’ will be displayed and the first OFF 1 time will now be flashing. If 
you do not wish to change the time, press the green   button and move to the next 
step. Otherwise, use the 
   or 
 buttons to change the time. Press the green 
 button to confirm the time is correct and move to the next step. ‘SAVED’ will be 
displayed for a moment to confirm that any change has been saved to memory.
d.  The remaining ON and OFF times (ON 2, OFF 2, ON 3, OFF 3) can be set by 
using the     or   buttons to change the time, and the green   button to 
confirm  the  time  is  correct  and  move  to  the  next  step.  If  you  do  not  wish  to 
change  the  time,  just  press  the  green    button  to  move  directly  to  the  next 
ON/OFF time without making any changes.
e.  After setting or reviewing the last off time, OFF 3, the message ‘COMPLETE’ will 
be displayed to indicate the times for Monday have been set.
You now have a choice of how to set the programme for the next day:
Copying one day’s Programme to another day (example Monday to Tuesday):
f.  Whilst the day is showing Monday, Press the COPY DAY button. The message 
‘COPY MON TO TUESDAY OK?’ will be displayed and the letters TUE will flash 
to indicate the programme for Monday can be copied to Tuesday.
g.  To select a different day to copy to, press the NEXT DAY button to cycle through 
the days. With each press of the NEXT DAY button the message will change to 
indicate the new day you are copying to.
h.  When the required day is indicated, press the green 
 button to confirm, and 
the message ‘MON COPIED’ will be displayed for a moment. The day into which 
Mondays programme has been copied is now available to have its programme 
edited.
Note: Once a day’s programme has been confirmed in this way, it now becomes the 
day whose programme is copied if the COPY DAY button is pressed again.
OR
Programming a Different Day:
i.  Press the NEXT DAY button to select the next day, which is displayed along the
