Conventions Used in this Guide

Pay Special Attention: Instructions that are important to
remember and may prevent mistakes.

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 while performing maintenance procedures on the speakers.

6.1 Packing requirement for sending the PCB assembly by post

PCB assembly is a kind of sophisticated electronic circuit board. Well packing
Will be required when sending them by post.
*Some sophisticated IC components are mounted on the PCB assembly, hence
it is necessary to pack each PCB assembly with a separate static protecting bag,
in order to avoid static electricity.
*Reliable external packing is also very important when sending the PCB assembly
by post, in that it would avoid unnecessarily lost or damage.

6.2 Short of spare parts while repairing a speaker system

If you are short of spare parts when you have some spesker systems waiting to
be repaired,it would be recommended to take the necessary parts from one
Speaker system,so that you may haye the as many speaker systems
