required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate nor-
mally, or has been dropped.
15. Use the mains plug to disconnect the apparatus from the mains.
16. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC

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 compli-
ance 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.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers 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
preamplifi er or other sensitive equipment at the top.
磁场
警告！不要把敏感的高增益设备，如前置放大器或大型录音机直接放在其上或者旗
下，因为此功放具有大功率密度，形成强磁场，这种磁场会使靠近的未屏蔽的设备
产生嘈杂声。扩音器的上部和下部磁场最强。
如果使用设备架，我们建议把功放放在架的底部，把前置放大器或者其他敏感设备
放在架顶。
