User manual B&W CMC

[. . . ] 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. 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. [. . . ] Keep the total impedance below the maximum recommended in specification and use a low inductance cable to avoid attenuation of the highest frequencies. Neither transportation, nor any other costs, nor any risk for removal, transportation and installation of products is covered by this warranty. 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. 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. 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. Adjust the level of the surround speakers so that, except for special effects, your attention is not unduly attracted to them. Sit in all likely listening positions when deciding on the optimum levels. If you want to reduce the bass level without moving the speaker further from the wall, fit the foam bung in the port tube. (Figure 4) Consult your decoder manual for further information on how to set the levels. 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. [. . . ] As a guide, allow up to a week for the temperature effects to stabilise and 15 hours of average use for the mechanical parts to attain their intended design characteristics. 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. [. . . ]
