Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Kramer VP-794. Le manque du manuel d’utilisation ou les informations incorrectes fournies au consommateur sont à la base d'une plainte pour non-conformité du dispositif avec le contrat.

La condition est son caractère lisible et compréhensible.

Qu'est ce que le manuel d’utilisation?

Le mot vient du latin "Instructio", à savoir organiser. Ainsi, le manuel d’utilisation Kramer VP-794 décrit les étapes de la procédure.

- instructions d'utilisation, de réglage et d’entretien de l'équipement Kramer VP-794
- signes de sécurité et attestations confirmant la conformité avec les normes pertinentes
