Informations de base relatives au chargement
Un cycle de charge complet prend environ 2 heures. Avant d’utiliser le casque
pour la première fois, chargez sa batterie intégrée pendant un cycle de charge
complet et sans interruption.
Quand la batterie est faible ou le casque est en cours de chargement, la LED
s’allume ou clignote comme indiqué dans le tableau ci-dessous. Vous entendez
une invite vocale qui annonce l’état de charge de la batterie. Quand la charge
de la batterie a atteint un niveau très bas, une invite vocale vous demande de
recharger le casque.
Il est conseillé de ne charger le casque qu’avec le câble USB fourni. Si vous
chargez le casque avec un bloc secteur USB externe, il est conseillé d’utiliser un
bloc secteur avec une puissance nominale de 500 mA ou plus.
