Explanation of Graphical 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.

4. Follow instructions - All operating and users’ instructions should be followed.
5. Installation - Install in accordance with the manufacturers’ 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 powersupply 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.
10. Ventilation - The product must be properly ventilated. Do not place the product on a bed, sofa, or other
similar 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 product.
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.
15. Attachments - Do not use attachments not recommended by the product manufacturers, as they may
cause hazards.
16. Accessories - Do not place this product on an unstable cart, stand, tripod, bracket or table. The product
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 the manufacturer or sold with the product. Any mounting of

replacement parts specified by the manufacturer or have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock or other hazards.
22. Mains fuses - For continued protection against fire hazard, use fuses only of the correct type and rating.
The correct fuse specification for each voltage range is marked on the product.
23. Do not turn up the volume while listening to a section with very low level inputs or no audio signals. If you
do, the speaker may be damaged when a peak level section is suddenly played.
24. The only means of completely disconnecting the product from the power supply is by removing the power
cord from the wall outlet or the product. The wall outlet or the power cord entry to the product must remain
