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. Precautions should be taken so that the grounding scheme on the unit is not defeated.

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.

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. If the AC supply cord is damaged DO NOT OPERATE THE UNIT.

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.

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 ultérieures et observez tous les avertissements.

Nettoyez seulement avec le tissu sec.

Emballage:

Conservez la boite au cas ou l’appareil devait être retourner pour réparation.

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.

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.

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. N’UTILISEZ PAS

L’APPAREIL si le cordon d’alimentation est endommagé.

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