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
