Bluetooth Tower Speaker User’s Guide for Model No. ITB124B v1068-01 2 Safety Instructions & Warnings Important Safety Instructions • Read these Instructions. • Keep these Instructions. • Heed all Warnings. • Follow all instructions. • Do not use this apparatus near water. • Clean only with a dry cloth. • Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. • Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. • Do not defeat the safety purpose of the polarized or ground- ing - 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. When the provided plug does not fit into your outlet, consult an electrician for replace- ment of the obsolete outlet. • Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. • Only use attachments/accessories specified by the manu- facturer. • Unplug this apparatus during lightning storms or when unused for long periods of time. • Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. • Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. FCC Warnings Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential instal- lation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interfer- ence will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Warning: To reduce the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer servicing to qualified service personnel. Warning: DO NOT INgEsT BaTTERy, CHEmICal BuRN HazaRD. ATTENTION RISQUE D' ÉLECTROCUTION NE PAS OUVRIR CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and mainte- nance (servicing) instructions in the literature accompanying the appliance. This symbol indicates that this product incor- porates double insulation between hazardous mains voltage and user accessible parts. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s en- closure that may be of sufficient magnitude to constitute a risk of electric shock to persons. FCC Radiation Exposure Statement This equipment complied with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. Customer Support: 1-888-999-42153 Safety Instructions & Warnings Additional Warnings and Precautions • CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT. Avis: AFIN DE PRÉVENIR LES CHOCS ÉLÉCTRIQUES, FAITES CORRESPONDRE LA FICHE BLANCHE DE LA PRISE À LA FENTE LARGE, INSÉREZ TOTALEMENT. • WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain, moisture, dripping, or splashing. Avis: Pour réduire le risque d'incendie ou de choc élec- trique, n'exposez pas cet appareil à la pluie ou l'humidité ou aux éclaboussures. • CaUTiOn: use of controls or adjustments or performance of procedures other than those specified may result in hazard- ous radiation exposure. Avis: L’utilisation de commande ou l’exécution de procé- dures autres que celles spécifiées ici peuvent aboutir à une exposition à des radiations dangereuses. • WARNING: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Avis: Des changements ou des modifications sur ce produit non expressément approuvés par la partie responsable de la conformité peut annuler le droit de l’utilisateur d’utiliser cet équipement. • WARNING: Do not place this unit directly onto furniture surfaces with any type of soft, porous, or sensitive finish. As with any rubber compound made with oils, the feet could cause marks or staining where the feet reside. We recom- mend using a protective barrier such as a cloth or a piece of glass between the unit and the surface to reduce the risk of damage and/or staining. Avis: Ne placez pas cette unité directement sur des surfaces de meubles dont la finition serait douce, poreuse ou …
