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 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 ampliﬁer(s) in the bottom of the rack and the preampliﬁer or other sensitive equipment at the top.

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept 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 user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply 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 and 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 television reception, which can be 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.
