ExplanationofGraphical Symbols:
The lightning flash 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 an electric shock to a person or 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 product.
WARNINGS:
1. Read Instructions - All the safety and operating instructions must be read before the product is operated.
2. Retain Instructions - The safety and operating instructions should be kept with the product for future
reference.
3. Heed warnings - All warnings on the product and in the operating instructions should be adhered to.
4. Follow instructions - All operating and users instructions should be followed.
5. Installation - Install in accordance with the manufacturer's instructions.
6. Power sources - This product should be operated only from the type of power source indicated by the
marking adjacent to the power cord entry. If you are not sure of the type of power supply to your home,
consult your product dealer or local power company.
7. Grounding or polarization - the product is not required to be grounded. Ensure the plug is fully
inserted into the wall outlet or extension cord receptacle to prevent blade or pin exposure. Some
versions of the product are equipped with a power cord fitted with a polarized alternating line plug (a
plug having one blade wide than the other). This plug will fit onto the power outlet only one way. This
is a 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 your electrician to replace your obsolete outlet. Do not defeat the
safety purpose of the polarized plug. When using an extension power-supply cord or a power-supply cord
other than that supplied with the appliance, it should be fitted with the appropriate molded plugs and carry
safety approval appropriate to the country of use.
8. Power cord protection - Power-supply cords should be routed so that they are not likely to be walked on,
kinked or pinched by items placed on or against them, paying particular attention to cords from plugs,
receptacles and the point where they exit from the appliance.
9. Overloading - Do not overload wall outlets, extension cords or multiple sockets, as this can result in a risk of
fire or electric shock.

surface. Do not cover the product with any items such as tablecloths, newspapers, etc.
11. Heat - The product should be situated away from heat sources such as radiators, heat registers, stoves, or
other products including amplifiers that produce heat. No naked flame sources, such as lighted candles,
should be placed on the apparatus.
12. Water and moisture - To reduce the risk of fire or electric shock, do not expose the product to train, dripping,
splashing or excessive moisture such as in a sauna or bathroom. Do not use this product near water, for
example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, or
etc.
13. Object and Liquid Entry - Never push objects of any kind into this product through openings, as they may
touch dangerous voltage points or short-circuit parts that could result in a fire or electric shock. Never spill
liquid of any kind on the product. Do not place any object containing liquid on top of the product.
14. Cleaning - Unplug the product from the wall outlet before cleaning. The cabinet of the subwoofer may be
cleaned by dusting with a dry cloth. If you wish to use an aerosol cleaning spray, do not spray directly on the
cabinet; spray onto the cloth. Be careful not to damage the drive units.

hazards.
