[. . . ] 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. Home Theatre (figure 2) As a front centre speaker: 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. [. . . ] This warranty will not be applicable in cases other than defects in materials and/or workmanship at the time of purchase and will not be applicable: for damages caused by incorrect installation, connection or packing, for damages caused by any use other than correct use described in the user manual, negligence, modifications, or use of parts that are not made or authorised by B&W, for damages caused by faulty or unsuitable ancillary equipment, for damages caused by accidents, lightning, water, fire heat, war, public disturbances or any other cause beyond the reasonable control of B&W and its appointed distributors, for products whose serial number has been altered, deleted, removed or made illegible, if repairs or modifications have been executed by an unauthorised person. This guarantee complements any national/regional law obligations of dealers or national distributors and does not affect your statutory rights as a customer. All Applications The speaker may be used in either vertical or horizontal orientation. However, vertical orientation offers better horizontal dispersion and is to be preferred in most cases as this leads to a more stable image over a wide listening area. Horizontal orientation can be used with little detriment to the imaging if the speaker is used in the front centre position of a home theatre installation where the listeners are within 15° of the centre line ­ equivalent to 0. Leave at least 10cm clear space between the back of the speaker and the wall behind, to allow the port to operate properly. They give a degree of vibration isolation, especially useful if placing the speaker directly on top of a fairly flimsy television. The flat area on top of the television may be smaller than the base of the speaker, so position the feet accordingly. Stray magnetic fields The speaker drive units are magnetically shielded such that the stray magnetic field outside the boundaries of the cabinet, 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. If you have a problem, first degauss the television set with the speaker in place. If not, switch off the set at the mains for 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 B&W national distributor in the country of residence who will advise Merely putting the set into standby mode is not sufficient. If you still have a problem, try moving the speaker either forwards or backwards a little to get a more favourable juxtaposition, or space the speaker further from the television until the distortion disappears. Because of the higher stray magnetic field in front of the speaker, we recommend you keep magnetically sensitive articles (computer discs, audio and video tapes, swipe cards and the like) at least 0. Home Theatre Refer to your decoder manual and set the levels and delay times for all the speakers. check the settings to obtain the best average result at all probable listening positions. Except for special effects, the general level of the surround field should not be too obvious. Adjust the spacing of the front left and right speakers so that the size of the acoustic image matches the size of the screen. Adjust the toe-in of the front left and right speakers to get a smooth transition of sounds that pan from one side to the other. [. . . ] Even small changes in the position of the speakers or the listeners can have a profound effect on how these resonances affect the sound. If the sound is too harsh, increase the amount of soft furnishing in the room (for example use heavier curtains), or reduce it if the sound is dull and lifeless. Test for flutter echoes by clapping your hands and listening for rapid repetitions. Reduce them by the use of irregular shaped surfaces such as bookshelves and large pieces of furniture. [. . . ]
