Salut,
apparement 1H c'est pas assez
Voila ce que ca dit chez Clarion :
Code:
Entering the wrong code will cause the systems
blocking device to activate and depending on which model
you have, the display screen will remain blank or say "Security"
In order for you to enter the correct code, you must leave your
radio's power turned on for up to 24hrs. The time delay will vary
depending on how many times you've tried to enter a code after
making the original mistake. "Code - In" or 4 zeros will eventually
flash in the display, providing you don't tamper with your radio during
the interim code clearance time. Once displayed enter the correct number
