Pay Special Attention: Instructions that are important to<br />
remember and may prevent mistakes.<br />
Caution: Information that, if not followed, may result in<br />
damage to the product.<br />
Safety Precautions<br />
The following precautions should be observed in handling the speaker described in<br />
this guide:<br />
Place the speakers on a flat, level and stable surface.<br />
Do not place the speakers in environments subject to mist, smoke, vibration, excessive<br />
dust, salty or greasy air, or other corrosive gases and fumes.<br />
Do not drop or jolt the speakers.<br />
Do not allow anything to drop into the subwoofer case through its ventilator, as it could<br />
result in fatal electric shock or fire.<br />
Place the unit far enough from other equipments for good heat dissipation.<br />
Disconnect the AC power cord from the AC outlet before performing any maintenance<br />
on the speakers.<br />
Do not perform any maintenance with wet hand.<br />
Prevent foreign substances, such as water, other liquids or chemicals, from entering the<br />
speakers while performing maintenance procedures on the speakers.<br />

Chapter 8. Important Notes<br />
8.1 Packing requirement for sending the PCB assembly by post<br />
PCB assembly is a kind of sophisticated electronic circuit board. Well packing<br />
will be required when sending them by post.<br />
* Some sophisticated IC components are mounted on the PCB assembly, hence<br />
it is necessary to pack each PCB assembly with a separate static protecting bag,<br />
in order to avoid static electricity.<br />
* Reliable external packing is also very important when sending the PCB assembly<br />
by post, in that it would avoid unnecessarily lost or damage.<br />
8.2 Short of spare parts while repairing a speaker system<br />
If you are short of spare parts when you have some speaker systems waiting to<br />
be repaired, it would be recommended to take the necessary parts from one<br />
speaker system, so that you may have the as many speaker systems<br />
