[. . . ] 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. There are 2 pairs of terminals at the back of the speaker which permit bi-wiring if desired. [. . . ] This guarantee complements any national/regional law obligations of dealers or national distributors and does not affect your statutory rights as a customer. After opening the top carton flaps, remove the accessories from the polystyrene tray. Remove the protection cover from the tweeter and fit the grille if required, applying pressure over the position of the pegs. 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. Keep the total impedance below the maximum recommended in the specification and use a low inductance cable to avoid attenuation of the highest frequencies. Do not fit the spike feet until you have found the best position for your speakers. Before fine tuning, double check that all the connections in the installation are correct and secure. Moving the speakers further from the walls will reduce the general level of bass. Space behind the speakers also helps to create an impression of depth. Conversely, moving the speakers closer to the walls will increase the level of bass. If you want to reduce the bass level without moving the speakers further from the wall, fit the foam plugs in the port tubes (figure 4). If the bass is uneven with frequency it is usually due to the excitation of resonance modes in the room. 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 you do not have a carpet, use a protective disc under the spikes to protect the floor surface. If you wish to use an aerosol cleaner, remove the grille first by gently pulling it away from the cabinet. The grille fabric may be cleaned with a normal clothes brush whilst the grille is detached from the cabinet. [. . . ]
