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.

6.1 Packing requirement for sending the PCB assembly by postPCB 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 speaker

systems waiting to be repaired, it would be recommended to take

the necessary parts from oneSpeaker system, so that you may have the as many speaker

systems
