Operation
Every time you turn the key from ON to OFF, the
protection system activates the engine block.
If also in this case you are not able to start the engine,
contact an authorised Ducati service centre.
Warning
Strong impacts could damage the electronic
components inside the key. During the procedure
always use the same key. Using different keys may
prevent the system from acknowledging the code of
the inserted key.
