PRECAUTIONS
Place the system near a power outlet so you can easily plug it in. Connect the included power cord only to an AC outlet of the type stated in this manual or printed on the system. Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord in case you damage it. Do not scratch, bend, twist, pull, or heat the power cord. Do not place heavy objects, including this unit, on top of the power cord. Be careful not to place heavy objects on a power cord covered by a carpet, either. A damaged power cord can easily cause fire or electrical shock hazard. If the power cord is damaged (i.e., cut or a bare wire is exposed), ask the local dealer for a replacement. Using the unit with a damaged power cord can easily cause fire or electrical shock hazard. Do not touch the power plug with wet hands. Doing so may lead to potential electrical shock hazard. Should this unit be dropped or the cabinet be damaged, turn the power switch off immediately. Then remove the power plug from the AC outlet, and contact the local dealer. If you ignore it and continue to use the unit without following this instruction, fire or electrical shock is a very likely result. If you smell anything, or notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid gets inside the unit, turn it off immediately. Remove the power cord from the ACoutlet. Consult your dealer for repair. Using the unit in this condition could easily cause fire or electrical shock hazard. Turn off all audio equipment and speakers when connecting to this unit. Use the correct connecting cables and connect as specified.
Always lower the volume control to the minimum level before turning power on. A sudden blast of sound may cause hearing discomfort. When rack-mounting the unit, allow enough free space around the unit for normal ventilation. For normal ventilation during operation, remove the rear of the rack or open a ventilation hole. If the airflow is not adequate, the unit will heat up inside and may cause fire. If you stack the speakers, secure the handles of the speakers by using a belt and fix the speakers to the floor or wall to prevent them from falling and causing injury. Without safety protection in advance, do not stack more than two speakers. Do not use the handles to suspend the speaker; it may otherwise fall and cause injury. XLR-type connectors are wired as follows: pin 1=ground, pin 2=hot(+), and pin 3=cold(-). Using a mobile telephone near this unit may induce noise. If noise occurs, take the telephone away from the unit. Do not use the speaker at uncomfortably loud level that may cause hearing discomfort. Do not allow water to spill into this system or allow the unit to become wet, which may result in electrical shock. Do not place a container with liquid or small metal objects on top of this system. Liquid or metal objects inside this system are could easily cause fire or electrical shock hazard. Do not remove the unit� s cover. You would likely receive an electrical shock. If internal inspection, maintenance, or repair is necessary, please refer to your dealer. Do not modify the unit under any circumstance. Doing so can easily cause fire or electrical shock hazard.
