[. . . ] On smooth surfaces like marble, glass or highly polished wood, vibrations may cause the speakers to slide. So be sure to attach the selfadhesive rubber feet to the bottom surface of each speaker for added stability and protection. The feet go in the corners of the flat surface, inside the seam. English Do not use these speakers in a moving vehicle. To mount the speakers on a wall, use only the Bose WB-3 wall mounting bracket. Please follow the mounting instructions that come with these brackets. Improperly mounted speakers may fall, causing injury and damage. To contact Bose, please refer to the subsidiary offices listed on the inside back Figure 2 cover of this owner's guide. Placement guidelines Note: Bose speaker stands or wall brackets can extend your placement options.

Standard zip cord (2-conductor, 18-gauge wire) works for most applications. You can find this wire at most electrical and hardware stores. You will need thicker wire if your speakers will be more than 30 feet (9 m) from a receiver (or amplifier). Refer to the wire recommendations under "Technical information" on page 10, or contact your authorized Bose® dealer for more information. CAUTION: Never use broken or frayed wiring, which can result in electrical shock or damage. Note: Before running speaker cord through a wall or under a floor, check your local building code requirements and safety regulations. You may want to contact an electrical installer for this information. Prepare the cord Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed). This marked wire is always positive (+). The plain wire is always negative (­). These wires correspond to the red (+) and black (­) terminals on the speakers and the receiver. At the ends of each cord, strip approximately 1/2 inch (12 mm) of insulation from both wires. Twist the bare end of each wire so loose strands will not touch across terminals. Be sure to connect each wire to the proper terminal (positive to positive and negative to negative). Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully. Make the connections Just press the terminal tab on the back of each speaker to insert the appropriate wire (Figure 3). Connect one speaker cord to your right speaker. [. . . ] The speaker grille panels require no special care. You may vacuum them carefully to remove dust.
