Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must a

18、ccept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. NOTE: This equipment has been tested and found to comp

19、ly with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed a

20、nd used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or televi- sion reception, which can be

21、determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circui

22、t different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. IMPORTANT M Series amplifiers require Class 2 output wiring.

23、Produktionsverdrah- tung. Los amplificadores de la Serie M requieren de un cableado de sal- ida Clase 2. MAGNETIC FIELD CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the unit. Because this amplifier has a high power density, it has a

24、 strong magnetic field which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit. If an equipment rack is used, we recommend locating the ampli- fier(s) in the bottom of the rack and the preamplifier or other sensi- tive equipment at t
