Reconnect the power cord only after making all signal connections. Connect the loudspeaker to a twopole, three- wire
grounding mains receptacle. The receptacle must be connected to a fuse or circuit breaker. Connection to any other
type of receptacle poses a shock hazard and may violate local electrical codes. Do not allow water or any foreign object
to get inside the loudspeaker. Do not put objects containing liquid on or near the unit. To reduce the risk of overheating
the loudspeaker, avoid exposing it to direct sunlight. Do not install the unit near heat-emitting appliances, such as
a room heater or stove. This loudspeaker contains potentially hazardous voltages. Do not attempt to disassemble
the unit. The unit contains no user serviceable parts, repairs should be performed only by factory trained service
personnel.
