Un point important après l'achat de l'appareil (ou même avant l'achat) est de lire le manuel d'utilisation. Nous devons le faire pour quelques raisons simples:
Si vous n'avez pas encore acheté HP (Hewlett-Packard) HP 50g c'est un bon moment pour vous familiariser avec les données de base sur le produit. Consulter d'abord les pages initiales du manuel d'utilisation, que vous trouverez ci-dessus. Vous devriez y trouver les données techniques les plus importants du HP (Hewlett-Packard) HP 50g - de cette manière, vous pouvez vérifier si l'équipement répond à vos besoins. Explorant les pages suivantes du manuel d'utilisation HP (Hewlett-Packard) HP 50g, vous apprendrez toutes les caractéristiques du produit et des informations sur son fonctionnement. Les informations sur le HP (Hewlett-Packard) HP 50g va certainement vous aider à prendre une décision concernant l'achat.
Dans une situation où vous avez déjà le HP (Hewlett-Packard) HP 50g, mais vous avez pas encore lu le manuel d'utilisation, vous devez le faire pour les raisons décrites ci-dessus,. Vous saurez alors si vous avez correctement utilisé les fonctions disponibles, et si vous avez commis des erreurs qui peuvent réduire la durée de vie du HP (Hewlett-Packard) HP 50g.
