MILOMETER
The display has 7 segments and is configured almost like a DOT matrix in order to produce a similar configuration to the DOT matrix on the HIGH LINE type panel.
The panel receives information, from the B-CAN line, concerning the space travelled processed by the NBC and information coming from the NFR and increases the milometer and the trip meter
The km travelled are displayed in an LCD 1 which also displays information concerning the headlamp alignment.
The light in the display is green and is produced by an SMD LED.
The LCD has 6 digits (with 7 segments for each digit) for the 'total' figure and 4 digits plus a decimal point for the 'partial' figure. The zeros which are not important are not displayed in order to restrict the numbers illustrated to the
significant ones.
By pressing the 0 km' button (outside the NQS) for 1x < t < 3 x the partial counter is zeroed, but the mileage counter is not, nor the trip distance, nor the Service mileage.
The instrument memorizes the total km so that if the battery (+30) is disconnected no more than +/- 1 km is lost. whilst for the partial mileage counter, the total memory is lost.
The instrument is supplied by the factory with the possibility of resetting the total mileage counter only once during the first 200 km (or 125 miles).
The possibility of this zeroing is shown on the LCD by the letter 'H' at the first digit (7 segments) on the left.
If the operation described previously is carried out before 200 km is reached, the total mileage counter is zeroed (the partial mileage recorder is zeroed, the Trip meter is zeroed, the Service mileage is zeroed) if the '0 km' button is pressed for t
> 10 s the letter H disappears.
If this operation is not carried out when 200 km is reached/exceeded, the letter H disappears and the km travelled are maintained and displayed and the possibility of zeroing the total mileage counter is lost.
NOTE:
The instrument allows the programming of the total number of km (if it is replaced) on condition that the figure entered is higher than the last figure memorized.
NOTE:
When the maximum mileage is reached by the total mileage counter (699999 km - 399999 miles) it is not zeroed but horizontal bars are displayed. When 999.9 km is reached, the partial mileage recorder returns to 0.0
