Conventions Used in this 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 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 substances, such as water, other liquids or chemical, from
entering the speakers while performing maintenance procedures on the
speakers.

Chapter 7. Important Notes
7.1 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 PCB
assembly by post, in that it would avoid unnecessarily lost or damage.
7.2 Short of Spare Parts while Repairing a Speaker System
Version 1.0 Page 18 of 18
If you are short of spare parts when you have some speaker systems waiting
to be repaired, it would be recommended to take the necessary parts form
one speaker system, so that you may have the as many speaker systems.
