Getting Started
Conventions Used in the Guide
Pay Special Attention: Instructions that are important to remember and may prevent
mistakes.
Caution: Information that, if not followed, may result in damage to the product.
Safety Precautions
The following precautions should be observed in handing 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.
Do not perform any maintenance with wet hand.
Prevent foreign substance, such as water, other liquids or chemical, from entering
the speakers while performing maintenance procedures on the speakers.
