Safety Precautions 

 
The following precautions should be observed in handling the speaker described in this guide: 
Place the speakers on a flat level and stable surface. 
Do not place the speakers in environments subject to mist, smoke, vibration, excessive dust, salty 
or greasy air, or other corrosive gases and fumes. 
Do not drop or jolt the speakers. 
Do not allow anything to drop into the subwoofer case through its ventilator, as it could      result 
in fatal electric shock or fire. 
Place the unit far enough from other equipments for good heat dissipation. 
Disconnect the AC power cord from the AC outlet before performing any maintenance on the 
speakers. 
Do not perform any maintenance with wet hand. 
Prevent foreign substance, such as water, other liquids or chemicals, from entering the speakers
