[. . . ] To validate your warranty, you will need to produce this warranty booklet completed and stamped by your dealer on the date of purchase. Alternatively, you will need the original sales invoice or other proof of ownership and date of purchase. Except the front, is too low to cause distortion of the television picture in the vast majority of cases. There are, however, some extremely sensitive televisions ­ some that even have to be adjusted according to their alignment with the earth's magnetic field. [. . . ] On delivery, the separate pairs are connected together with high-quality links for use with a single 2-core cable. For single cable connection, leave the links in place and use either pair of terminals on the speaker. ensure the positive terminal on the speaker (marked + and coloured red) is connected to the positive output terminal of the amplifier and negative (marked ­ and coloured black) to negative. To bi-wire, remove the links by loosening the terminal caps and use a separate 2-core cable from the amplifier to each pair of terminals. When bi-wiring, incorrect connection can also impair the frequency response. The terminals accept 6mm (1/4-in) spades, bared wire ends or round pins up to 6mm diameter and 4mm banana plugs. Important safety notice: In certain countries, notably those in Europe, the use of 4mm banana plugs is considered a potential safety hazard, because they may be inserted into the holes of unshuttered mains supply sockets. In order to comply with European CENELEC safety regulations, the 4mm holes in the ends of the terminals are blocked by plastic pins. Do not remove the pins if you are using the product where these conditions apply. Always screw the terminal caps down tightly to optimise the connection and prevent rattles. If using a projection television with an acoustically transparent screen, place the speaker behind the centre of the screen. Otherwise position it directly above or below the screen, whichever is closest to ear level. The flat area on top of the television may be smaller than the base of the speaker, so position the feet accordingly. Should service be required, please follow the following procedure: 1 If the equipment is being used in the country of purchase, you should contact the B&W authorised dealer from whom the equipment was purchased. If the equipment is being used outside the country of purchase, you should contact the B&W national distributor in the country of residence who will advise where the equipment can be The speaker drive units are magnetically shielded such that the stray magnetic field outside the boundaries of the cabinet, Ask your dealer for advice when choosing cable. Keep the total impedance below the maximum recommended in specification and use a low inductance cable to avoid attenuation of the highest frequencies. This process can take several days or even weeks, but may be accelerated by careful use of an ultra-violet lamp. For greatest realism in home theatre installations it is important to balance the speakers and adjust the acoustic image to match the size of the screen. With smaller screens it may be more realistic to have the left and right speakers closer together than you might for audio alone. Adjust the levels of the three front speakers to get a smooth transition of sounds as they pan across the screen. [. . . ] Avoid touching the drive units, especially the tweeter, as damage may result. Please be aware that, like all natural materials, the wooden cabinet of the speaker will respond to its environment. Keep the product away from sources of direct heat such as radiators and warm air vents to avoid the risk of cracking. The wood is treated with an ultra-violet resistant lacquer to minimise changes in colour over time, but a degree of change is to be expected. [. . . ]
