THIS DEVICE IS FOR INDOOR USE ONLY!

Read Instructions: The Owner’s Manual should be read and understood before operation

of your unit. Please, save these instructions for future reference and heed all warnings.
Clean only with dry cloth.
Packaging: Keep the box and packaging materials, in case the unit needs to be

returned for service.
Warning: To reduce the risk or fire or electric shock, do not expose this apparatus to rain or

moisture. Do not use this apparatus near water!
Warning: When using electric products, basic precautions should always be followed,

including the following:

Power Sources

Your unit should be connected to a power source only of the voltage specified in the
owners manual or as marked on the unit. This unit has a polarized plug. Do not use
with an extension cord or receptacle unless the plug can be fully inserted. Precau-

tions should be taken so that the grounding scheme on the unit is not defeated. An
apparatus with CLASS I construction shall be connected to a Mains socket outlet with
a protective earthing ground. Where the MAINS plug or an appliance coupler is used

as the disconnect device, the disconnect device shall remain readily operable.

Hazards

Do not place this product on an unstable cart, stand, tripod, bracket or table. The
product may fall, causing serious personal injury and serious damage to the product.
Use only with cart, stand, tripod, bracket, or table recommended by the manufacturer
or sold with the product. Follow the manufacturer’s instructions when installing the
product and use mounting accessories recommended by the manufacturer. Only use

attachments/accessories specified by the manufacturer

Note: Prolonged use of headphones at a high volume may cause

health damage on your ears.

The apparatus should not be exposed to dripping or splashing water; no objects

filled with liquids should be placed on the apparatus.

Terminals marked with the “lightning bolt” are hazardous live; the external wiring
connected to these terminals require installation by an instructed person or the use of
ready made leads or cords.

Ensure that proper ventilation is provided around the appliance. Do not install near
any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.

No naked flame sources, such as lighted candles, should be placed on the apparatus.

Power Cord

Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug
has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding prong. The wide blade or the third prong are provided for your safety. If the

provided plug does not fit into your outlet, consult an electrician for replacement of the

obsolete outlet. The AC supply cord should be routed so that it is unlikely that it will be
damaged. Protect the power cord from being walked on or pinched particularly at plugs. If
the AC supply cord is damaged DO NOT OPERATE THE UNIT. To completely disconnect
this apparatus from the AC Mains, disconnect the power supply cord plug from the AC

receptacle. The mains plug of the power supply cord shall remain readily operable.

Unplug this apparatus during lightning storms or when unused for long periods of time.

Service

The unit should be serviced only by qualified service personnel. Servicing is required

when the apparatus has been damaged in any way, such as power-supply cord or plug is

CONSULTEZ UN TECHNICIEN QUALIFIE POUR L’ENTRETIENT

CE PRODUIT EST POUR L’USAGE À L’INTÉREUR SEULEMENT

Veuillez Lire le Manuel: Il contient des informations qui devraient êtres comprises avant

l’opération de votre appareil. Conservez. Gardez S.V.P. ces instructions pour consultations

Avertissement: Pour réduire le risque de feu ou la décharge électrique, n'exposez pas

cet appareil à la pluie ou à l'humidité. N’utilisez pas cet appareil près de l’eau!
Attention: Lors de l’utilisation de produits électrique, assurez-vous d’adhérer à des

précautions de bases incluant celle qui suivent:

Alimentation

L’appareil ne doit être branché qu’à une source d’alimentation correspondant au
voltage spécifié dans le manuel ou tel qu’indiqué sur l’appareil. Cet appareil est équipé

d’une prise d’alimentation polarisée. Ne pas utiliser cet appareil avec un cordon de

raccordement à moins qu’il soit possible d’insérer complètement les trois lames. Des
précautions doivent êtres prises afin d’eviter que le système de mise à la terre de

l’appareil ne soit désengagé. Un appareil construit selon les normes de CLASS I

devrait être raccordé à une prise murale d’alimentation avec connexion intacte de mise
à la masse. Lorsqu’une prise de branchement ou un coupleur d'appareils est utilisée
comme dispositif de débranchement, ce dispositif de débranchement devra demeurer
pleinement fonctionnel avec raccordement à la masse.

Risque

Ne pas placer cet appareil sur un chariot, un support, un trépied ou une table instables.

L’appareil pourrait tomber et blesser quelqu’un ou subir des dommages importants.
Utiliser seulement un chariot, un support, un trépied ou une table recommandés par le

fabricant ou vendus avec le produit. Suivre les instructions du fabricant pour installer

l’appareil et utiliser les accessoires recommandés par le fabricant. Utilisez seulement

les attachements/accessoires indiqués par le fabricant

Note: L'utilisation prolongée des écouteurs à un volume élevé peut

avoir des conséquences néfastes sur la santé sur vos oreilles. .

Il convient de ne pas placer sur l’appareil de sources de flammes nues, telles que

des bougies allumées.

L’appeil ne doit pas être exposé à des égouttements d’eau ou des éclaboussures

et qu’aucun objet rempli de liquide tel que des vases ne doit être placé sur l’appareil.

Assurez que lappareil est fourni de la propre ventilation. Ne procédez pas à

l’installation près de source de chaleur tels que radiateurs, registre de chaleur, fours
ou autres appareils (incluant les amplificateurs) qui produisent de la chaleur.

Les dispositifs marqués d’une symbole “d’éclair” sont des parties dangereuses
au toucher et que les câblages extérieurs connectés à ces dispositifs de
connection extérieure doivent être effectivés par un opérateur formé ou en utilisant
des cordons déjà préparés.

Cordon d’Alimentation

Ne pas enlever le dispositif de sécurité sur la prise polarisée ou la prise avec tige de

mise à la masse du cordon d’alimentation. Une prise polarisée dispose de deux lames
dont une plus large que l’autre. Une prise avec tige de mise à la masse dispose de
deux lames en plus d’une troisième tige qui connecte à la masse. La lame plus large ou
la tige de mise à la masse est prévu pour votre sécurité. La prise murale est désuète si
elle n’est pas conçue pour accepter ce type de prise avec dispositif de sécurité. Dans
ce cas, contactez un électricien pour faire remplacer la prise murale. Évitez
d’endommager le cordon d’alimentation. Protégez le cordon d’alimentation. Assurez­vous qu’on ne marche pas dessus et qu’on ne le pince pas en particulier aux prises.

N’UTILISEZ PAS L’APPAREIL si le cordon d’alimentation est endommagé. Pour
débrancher complètement cet appareil de l’alimentation CA principale, déconnectez le

cordon d’alimentation de la prise d’alimentation murale. Le cordon d’alimentation du
bloc d’alimentation de l’appareil doit demeurer pleinement fonctionnel.

Débranchez cet appareil durant les orages ou si inutilisé pendant de longues périodes.

Service

Consultez un technicien qualifié pour l’entretien de votre appareil. L'entretien est
nécessaire quand l'appareil a été endommagé de quelque façon que se soit. Par exemple

qui a été renversé à l’intérieur ou des objets sont tombés dans l'appareil, si l'appareil a été
exposé à la pluie ou à l'humidité, si il ne fonctionne pas normalement, ou a été échappé.
