This product is a sub woofer system which has been designed using time domain theory in order to play back high speed and tight low-pitched sounds. What is time domain theory? Time domain recreates the changes that occur in sound waves over time from the moment of output until their disappearance. Its purpose is to reproduce those sound waves that are as close as possible to the original recorded sound. Time domain audio systems allow sound orientation and the nuances that are added by recorded performers to be faithfully reproduced. Important Safety Instructions CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN Explanation of Graphical Symbols The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. ATTENTION POUR EVITER LES CHOC ELECTRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRESPONDANTE DE LA PRISE ET POUSSER JUSQU'AU FOND. CAUTION for customers who concerned TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT FULLY INSERT. CAUTION : TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK).

General care of unit Do not open or modify the unit as fire or electric shock may result. Do not place flower vases, potted plants, cups, cosmetics, drugs, containers holding liquids, or small metal objects on or near the unit. Do not place any objects on the unit and do not insert or drop metal, combustible objects or liquids into the unit as such actions can cause fire or electric shock. If liquid or foreign objects enter the unit, disconnect immediately since continued use may result in fire or electric shock. Do not place the unit on tuners, audio decks or other electric equipment. Do not use the unit as a step or seat. The unit may tip over and cause damage or injury. Consult a company customer service facility for interior inspection, adjustment or repair. 7. Where not to use unit Do not use the unit in bathrooms, areas exposed to rain or snow, on the shore, near water or in humid conditions. Do not place the unit in unstable locations, in kitchens,near humidifiers, or in any location with likely exposure to smoke or steam. Do not place the unit in direct sunlight, near heating equipment or close to open flames. Fire, accident or malfunction may result. Do not place the unit in locations exposed to cold air or direct draft. Condensation, leakage current or thermal damage may result. Do not use the unit in dusty or dirty locations. Decreased heat ventilation can cause thermal damage 8. Unit heat The bottom and sides of the unit can heat up during use and should not be touched. Burns may result. Only connect or disconnect speaker cables after the power supply has cooled down. 9. Moving the unit When moving the unit, shut off power to all connected equipment, and disconnect power cords, connectoins cables, speaker cables and other wires. Moving the unit while cable are connected can cause damage to cables, fire or electric shock. The unit is heavy and care should be taken when unpacking, moving or lifting. Manufacturing also creates sharp areas on the unit; use thorough care in handling. 10. Power cord Only use the power cord supplied and do not bend, twist, modify it for repair, or pin it under the unit. Heavy objects, heat or tension may also damage the power cord and cause fire or electric shock. When disconnecting the power cord from an outlet, do not pull the cord. Pulling on the cord can damage it and cause fire or electric shock. Do not touch the power cord with wet hands. Do not place the power cord near heating equipment and do not use the unit. If the plug fits loosely in an electric outlet or the plug or cord is hot. If the cord is damaged replace it as continued use may result in fire or electric shock. 11. Unit plug Insert the plug into an outlet all the may to its 12. 13. 14. 15. 16. base. Incomplete insertion can cause heat production, and dust build-up can cause fire. Contact with the prongs of the plug can also cause electric shock. Do not connect the unit to an outlet where the connection is loose even when the plug is inserted all the way to its base. Do not use the unit if the plug is hot. Heat production can cause fire. If dust or metal accumulates on or near the prongs of the plug, wipe the plug with a dry cloth after disconnection. Continued use may cause fire or electric shock. Danger signs If you notice a strange noise, smoke, unusual odour or other abnormal condition, shut off the unit, disconnect the power cord from the outlet and have the unit inspected. Continued use may result in fire or electric shock. Electric storms During electrical storms disconnect the unit and avoid contact with the antenna and power cord. Lightning can cause fire, electric shock and malfunction. Internal temperature rise To avoid internal temperature rise when installing the unit, leave space between the unit and walls or other equipments. When installed in a rack or similar fixture, leave a 10cm (4") or larger gap on top and at sides since internal temperature rise can result in fire. The unit is provided with ventilation holes to prevent internal temperature rise. Blockage of these holes decreases ventilation and can result in fire. Note the following: Do not place the unit in a poorly ventilated area Do not place the unit on carpeting or on bedding Do not obstruct the ventilation holes Do not tilt the unit or turn upside down Extended non-use If the unit is likely to be unused for an extended period, shut off power and disconnect from power supply. Volume Adjustment If abnormal noise is produced during play at high volume, reduce the volume level. Distorted sound can cause overheating of speakers and amplifier. Before switching 17. 18. 19. 20. 21. 22. power supply on, set the amplifier volume to minimum. Sudden, loud noise can cause damage to hearing. Connecting TV/other audio equipment When connecting a TV or other audio equipment, always shut off power, read the operating manual for each device and follow the instructions for connection. Use only designated cables. Use of non-designated cables or extension cables can cause heat production, burns, and fire. Antenna An outdoor antenna should be located away from power lines. Maintenance. Before undertaking maintenance disconnect from power supply. Have the interior of the unit cleaned approximately once a year by qualified personnel. Accumulated dust inside and long intervals without cleaning can cause fire or malfunction.
