READ these instructions. 2. KEEP these instructions. 3. HEED all warnings. 4. FOLLOW all instructions. 5. DO NOT use this apparatus near water. 6. CLEAN ONLY with dry cloth. 7. DO NOT block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. 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 wider 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. 10. PROTECT the power cord from being walked on or pinched, partic ularly at plugs, convenience receptacles, and the point where they exit from the apparatus. 11. ONLY USE attachments/accessories specified by the manufacturer. 12. 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. 13. UNPLUG this apparatus during lightning storms or when unused for long periods of time. 14. REFER all servicing to qualified service personnel. Servicing is req uired 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 ex posed to rain or moisture, does not operate normally, or the been dropped. 15. DO NOT expose this apparatus to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the apparatus. 16. To completely disconnect this apparatus from the AC Mains, disc onnect the power supply cord plug from the AC receptacle. 17. The mains plug of the power supply cord shall remain readily operable. Protective earthing terminal. The apparatus should be connect ed to a mains socket outlet with a protective earthing connection. Voltage selector: Used to adjust the input rating (120 Vac/60 Hz a nd 230 Vac/50 Hz), please just insert the mains power plug into t he socket-outlet with voltage within the setting of the selector. T he current ratings of mains fuse links are different for different in put rating (see marking for details), and the fitted mains fuse link was just related to the input rating as setting of the selector during factory assembly line work, please ask a qualified personnel to he lp you replace the mains fuse link before you adjust the voltage selector. The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. The lightning flash with arrowhead symbol within an eq uilateral triangle. is intended to alert the user to the pre sence of uninsulated “dangerous voltage” within the pro duct’s enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons. WARNING: To reduce the risk of fire or electrical shock, do not expose this apparatus to rain or moisture. WARNING: No naked flame sources-such as candles-should be placed on the product. Place the equipment near a main power supply outlet and make sure that you can easily access the power breaker switch. WARNING: This product is intended to be operated ONLY from the AC Voltages listed on the back panel or included power supply of the pro duct, Operation from other voltages other than those indicated may cause irreversible damage to the product and void the products war ranty. The use of AC Plug Adapters is cautioned because it can allow the product to be plugged into voltages in which the product was not des igned to operate, If the product is equipped with a detachable power cord, use only the type provided with your product or by your local di stributor and or retailer. If you are unsure of the correct operational voltage, please contact your local distributor and/or retailer.
