(In addition to this, the necessary note is each block.) Note: The components identi- fied by mark 0 or dotted line with mark 0 are criti- cal for safety. Replace only with part number specified.Note: Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro spécifié.
