1 Pour utiliser l’appareil au mieux de ses possibilités, lisez attentivement ce mode d’emploi.
Conservez-le soigneusement pour référence.
2 Installez cet ensemble audio dans un endroit bien aéré, frais, sec et propre - veillez à ce qu’il soit à
l’abri de la lumière directe du soleil, des sources de chaleur, des vibrations, des poussières, de
l’humidité et/ou du froid. Pour une ventilation correcte, ménagez l’espace minimum suivant.
Au-dessus : 10 cm, À l’arrière : 10 cm, Sur les côtés : 10 cm
3 Placez l’appareil loin des équipements, moteurs et transformateurs électriques, pour éviter les
ronflements parasites.
4 N’exposez pas l’appareil à des variations brutales de température, ne le placez pas dans un
environnement très humide (par exemple dans une pièce contenant un humidificateur) car cela peut
entraîner la condensation d’humidité à l’intérieur de l’appareil qui elle-même peut être responsable de
décharge électrique, d’incendie, de dommage à l’appareil ou de blessure corporelle.
5 Evitez d’installer l’appareil dans un endroit où des objets peuvent tomber, ainsi que là où l’appareil
pourrait être exposé à des éclaboussures ou des gouttes d’eau. Sur le dessus de l’appareil, ne placez pas :
d’autres appareils qui peuvent endommager la surface de l’appareil ou provoquer sa décoloration.
des objets se consumant (par exemple, une bougie) qui peuvent être responsables d’incendie, de
dommage à l’appareil ou de blessure corporelle.
des récipients contenant des liquides qui peuvent être à l’origine de décharge électrique ou de
dommage à l’appareil.
6 Ne couvrez pas l’appareil d’un journal, d’une nappe, d’un rideau, etc. car cela empêcherait l’évacuation
de la chaleur. Toute augmentation de la température intérieure de l’appareil peut être responsable
d’incendie, de dommage à l’appareil ou de blessure corporelle.
7 Ne branchez pas la fiche du câble d’alimentation de l’appareil sur une prise secteur aussi longtemps que
tous les raccordements n’ont pas été effectués.
8 Ne pas faire fonctionner l’appareil à l’envers. Il risquerait de chauffer et d’être endommagé.
9 N’exercez aucune force excessive sur les commutateurs, les boutons et les cordons.
10 Pour débrancher la fiche du cordon d’alimentation au niveau de la prise secteur, saisissez la fiche et ne
tirez pas sur le cordon.
11 Ne nettoyez pas l’appareil au moyen d’un solvant chimique, ce qui pourrait endommager la finition.
Utilisez un chiffon sec et propre.
12 N’alimentez l’appareil qu’à partir de la tension prescrite. Alimenter l’appareil sous une tension plus
élevée est dangereux et peut être responsable d’incendie, de dommage à l’appareil ou de blessure
corporelle. Yamaha ne saurait être tenue responsable des dommages résultant de l’alimentation de
l’appareil sous une tension autre que celle prescrite.
13 Pour empêcher tout dommage causé par les éclairs, déconnectez le câble d’alimentation et toute
antenne extérieure de la prise murale pendant un orage.
14 Ne tentez pas de modifier ni de réparer l’appareil. Consultez le service Yamaha compétent pour toute
réparation qui serait requise. Le coffret de l’appareil ne doit jamais être ouvert, quelle que soit la raison.
15 Si vous envisagez de ne pas vous servir de l’appareil pendant une longue période (par exemple, pendant
les vacances), débranchez la fiche du câble d’alimentation au niveau de la prise secteur.
16 Veuillez vous reporter à la section « Guide de dépannage » concernant les erreurs de fonctionnement
courantes avant d’en conclure que l’appareil est défectueux.
17 Avant de déplacer l’appareil, appuyez sur A pour placer l’appareil en veille puis débranchez la fiche du
câble d’alimentation au niveau de la prise secteur.
18 La condensation se forme lorsque la température ambiante change brusquement. En ce cas, débranchez
la fiche du câble d’alimentation et laissez l’appareil reposer.
19 La température de l’appareil peut augmenter en raison d’une utilisation prolongée. En ce cas, coupez
l’alimentation de l’appareil et laissez-le au repos pour qu’il refroidisse.
20 Installez cet appareil à proximité de la prise secteur et à un emplacement où la fiche du câble
d’alimentation est facilement accessible.
21 Les piles ne doivent pas être exposées à une chaleur extrême, par exemple au soleil, à une flamme, etc.
Lors de la mise au rebut des piles, suivez vos réglementations locales.
22 Une pression excessive du son par les écouteurs et le casque d’écoute peut entraîner la perte de l’ouïe.
n Remarques à propos des télécommandes et piles
Ne renversez aucun liquide sur le boîtier de télécommande.
Ne laissez pas tomber le boîtier delécommande.
Ne laissez pas et ne rangez pas le boîtier de télécommande dans les endroits suivants:
très humides, par exemple près d’un bain
très chauds, par exemple près d’un poêle ou d’un appareil de chauffage
exposés à des températures très basses
poussiéreux
Installez la pile en respectant les repères de polarité (+ et –).
Changez toutes les piles lorsque les symptômes suivants se présentent:
la portée du boîtier de télécommande diminue
le témoin de transmission ne clignote pas ou l’intensité est faible
Si la pile est plate, retirez-la immédiatement de la télécommande pour éviter tout risque d'explosion ou de
fuite d'acide.
Si vous remarquez une fuite au niveau des piles, mettez-les immédiatement au rebut en prenant soin de ne
pas toucher le produit qui a fui. Si le produit qui a fui entre en contact avec votre peau ou vos yeux ou
votre bouche, rincez immédiatement et consultez un médecin. Nettoyez soigneusement le logement des
piles avant de mettre en place des piles neuves.
N’utilisez pas à la fois des piles neuves et des piles usagées. Cela risque de réduire la durée de vie des
nouvelles piles ou d'entraîner une fuite des piles usagées.
N’utilisez pas non plus des piles de deux types différents (par exemple, des piles alcalines et des piles au
manganèse). Les caractéristiques des piles peuvent être différentes même si elles semblent identiques. Il
y a risque d’explosion en cas d’erreur dans la mise en place des piles.
Avant de mettre la nouvelle pile en place, essuyez soigneusement le compartiment.
Mettez la pile au rebut conformément aux lois en vigueur dans votre région.
Conservez les piles hors de portée des enfants. SI une pile est avalée accidentellement, contactez
immédiatement votre médecin.
Si vous prévoyez de ne pas utiliser la télécommande pendant une période prolongée, retirez les piles de la
télécommande.
N’essayez pas de charger ou de démonter les piles fournies.
ATTENTION : VEUILLEZ LIRE CE QUI SUIT AVANT D’UTILISER L’APPAREIL.
AVERTISSEMENT
POUR RÉDUIRE LES RISQUES D’INCENDIE OU DE DÉCHARGE ÉLECTRIQUE,
N’EXPOSEZ PAS CET APPAREIL À LA PLUIE OU À L’HUMIDITÉ.
Cet appareil n’est pas déconnecté du secteur tant qu’il reste branché à la prise de courant, même si
l’appareil en soi est éteint par la touche A. Il se trouve alors « en veille ». En mode veille,
l’appareil consomme une très faible quantité de courant.
