D'abord, Vous mettez le programme sur la calto.
2° vous lancez l'appli.
si le fichier du code n’existe pas encore, Le programme vous demandera de rentrez un mot de passe 2 fois.
ce mot de passe sera enregistré dans un fichier de 10 Octets
Maintenant,vous pouvez directement éteindre la calto ou sortir du prog avec (MENU) et puis étteindre la calto.
voilà, la calto est protégée.
si vous voulez, vous pouvez mettre un bout de scotch sur les circuits imprimés de votre calto à l'endroit du bouton reset.
ça le désactive.
