WBT50 Owners Manual Manuel de l’Utilisateur 5.25” Active Bluetooth Speakers Haut-parleurs amplifié Bluetooth à 133mm 1. Read Instructions - All the safety and operation instructions should be read before the sound bar is operated. 2 Reta Instructions - The safety and operating instructions should be kept for future reference. 3. Heed Warnings - All warnings on the sound bar and in these operating instructions should be followed. 4. Follow Instructions - All operating and other instructions should be followed. 5. Water and Moisture - The sound bar should not be used near water. For example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement or near a swimming pool. 6. Ventilation - The Sound Bar should be situated so that its location or position does not interfere with its proper ventilation. For example, the system should not be situated on a bed, sofa, rug or similar surface that may block airflow past the rear heat sinks; or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air past the heat sinks. 7. Heat - The sound bar should be situated away from heat sources such as radiators, heaters, furnace outflow vents or other devices which produce heat. 8. Power Sources - The Sound Bar should be connected to a power supply only of the type described in these operation instructions or as marked on the Component. 9. Grounding or Polarization - The sound bar is equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is an intentional safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact an electrician to replace the obsolete (unpolarized) outlet. Do not defeat the safety purpose of the polarized plug. 10. Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked upon or pinched by items placed upon or against them. Pay particular attention to cords at plugs, convenience receptacles, and the point where they exit the Sound Bar. To prevent electric shock, do not use the sound bar polarized plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. 11. Non-use Periods - The power cord of the sound bar should be unplugged from the outlet when left unused for a long period of time. 12. Damage Requiring Service - The sound bar should be serviced only by qualified service personnel when: A.Sound Bar power supply cord or the plug has been damaged; or B.Objects have fallen or liquid has spilled into the sound bar; or C. The sound bar has been exposed to rain; or D.The sound bar does not appear to operate or exhibits a marked change in performance; or E. The sound bar has been dropped or damaged. 13.Servicing - The user should not attempt to service the sound bar beyond those means described in this operating manual. All other servicing should be referred to an authorized Service Center. 14.Cleaning - Unplug the sound bar from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning. 15.Attachments - Do not use attachments not recommended as they may cause hazards. 16.Accessories - Do not place the sound bar on an unstable cart, stand, tripod, bracket, or table. The sound bar may fall, causing serious injury to a child or adult, and serious damage to the product. Use only with a cart, stand, tripod, bracket or table recommended by manufacturer, or sold with the product. Any mounting of the sound bar should follow manufacturer's instructions, and should use a mounting accessory recommended by manufacturer. An sound bar and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the product and cart combination to overturn. 17. Lightning - For added protection for the sound bar during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet. 18. Overloading - Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of fire or electric shock. 19. Safety Check - Upon completion of any service or repairs to…
