TO GO FROM SELF-SERVICE TO NORMAL OPERATING MODE (from Self-service to Z14)
Turn off the machine by the main power switch.
With the machine turned off, press STOP, keep it held down, and then turn the main power switch on,
holding it for 4 seconds, until a screen with four numbers appears.
When this screen is displayed, find number 1001 - pressing ON moves through the two digits on the
right, and pressing SELECT moves through those on the left – then press STOP (when you press
STOP the display will show ----) and then turn the machine off by the main power switch (if the machine
is not turned off, you cannot move out of this display).
When you turn the machine on again (you will first see the programme version and then code 1001)
the ON and SELECT buttons will have been enabled and machine is now ready to select the number
of oranges you want to squeeze and start operating when you press the ON button.
TO TURN ON THE SELF-SERVICE FUNCTION AGAIN
Repeat the process by entering the code 4104. This will disable the ON and SELECT buttons and the
machine will start working when you turn on the tap.
