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:
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.
The unit should be serviced only by qualified service personnel.

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.

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.
