both displays
Imbalance exceeds 999 grams. This signal can be triggered due to:
• Lack of machine calibration;
• Incorrect measuring of the wheel dimensions;
• Incorrect setting of the Wheel Type;
• Incorrect setting of the Program Type.
Flashing green STBY LED The machine is in the STAND-BY mode. All LEDs and displays are switched off. To exit the
STAND-BY mode press any button
(except for [P7] ).
The left (or right) display

calibrated.
a) The user's command may be the pressing a key
to confirm or continue the procedure in progress
or the selecting of a value or a menu option.
b) Call the technical support to carry on with the
calibration of the Diameter and Width sensor. To
