BST/GMT button until the red LED stops flashing and the printer reports the hour has been advanced or
retarded. (If you go over repeat the operation until the correct hour is shown)
• The date and time is factory programmed, this can be altered using the ‘747set.exe’ software utility, a copy of

commissioning and double address testing.
• The red LED on the front of the L747 flashes once per second when receiving good data from the network. If the
printer is switched off, set off line or not connected – the red LED will stop flashing. If the printer runs out of
paper – The data will be stored and printed out when the new paper roll is fitted.
