CALIBRATION (on vehicles with a-PRC)
Select the CALIBRATION function from the configuration menu to access the CALI-
BRATION function.
When the CALIBRATION function is selected (with vehicle at a standstill), a screen is
shown with the following message at the bottom of the display:
CALIBRATING
To calibrate the a-PRC (Aprilia Performance Ride Control) system, ride for approxi-
mately 10 seconds in a straight line on a flat section of road in second gear and at a
02_36
speed of 40 +/- 2 km/h (24.85 +/- 1.24 mph), until the message CALIBRATING is no
longer shown on the display.
NOTE
ONCE THE MESSAGE 'CALIBRATING' CEASES TO BE DISPLAYED, STOP THE
VEHICLE, TURN THE IGNITION SWITCH OFF AND LEAVE OFF FOR AT LEAST
30 SECONDS TO COMPLETE THE CALIBRATION PROCEDURE.
THIS ALLOWS THE CALIBRATION TO BE STORED IN THE MEMORY.
NOTE
THE CALIBRATION PROCEDURE IS USED TO OPTIMISE a-PRC FUNCTIONAL-
ITY IN THE EVENT OF CHANGING TYRE TYPE OR FINAL DRIVE RATIO (PINION-
SPROCKET COMBINATION).
IF THE VEHICLE IS FITTED WITH TYRES OTHER THAN THOSE INDICATED IN
THIS USE AND MAINTENANCE MANUAL, THE LEVEL SETTINGS OF THE SYS-
TEM MAY NEED TO BE MODIFIED IN ORDER TO OBTAIN THE SAME BEHAV-
IOUR AS BEFORE.
