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

Chapter 7. Important Notes<br />
7.1 Packing Requirement for Sending the PCB Assembly by Post<br />
PCB assembly is a kind of sophisticated electronic circuit board. Well<br />
packing will be required when sending them by post.<br />
* Some sophisticated IC components are mounted on the PCB assembly,<br />
hence it is necessary to pack each PCB assembly with a separate static<br />
protecting bag, in order to avoid static electricity.<br />
* Reliable external packing is also very important when sending PCB<br />
assembly by post, in that it would avoid unnecessarily lost or damage.<br />
7.2 Short of Spare Parts while Repairing a Speaker System<br />
If you are short of spare parts when you have some speaker systems waiting<br />
to be repaired, it would be recommended to take the necessary parts form<br />
one speaker system, so that you may have the as many speaker systems.<br />
