chassis assembly, be sure to use all 
protective stuffs including a nonmetal 
controlling handle and the covering of 
partitioning type. 
 
  Caution for design change : Do not install 
any additional devices to the module, and 
do not change the electrical circuit design. 
 
  For example: Do not insert a subsidiary 
audio or video connector. If you insert It, It 
cause danger on safety. And, If you change 
the design or insert, Manufactor guarantee 
will be not effect. .

parts get damaged. 
 
 
 
( Precaution when repairing ESD ) 
 
  There is ESD which is easily damaged by   
electrostatics.(for example Integrated circuit, 
FET ) Electrostatic damage rate of product 
will be reduced by the following technics 
 
  Before handling semiconductor 
parts/assembly, must remove positive 
electric by ground connection, or must wear 
the antistatic wrist-belt and ring. ( It must be 
operated after removing dust on it  –  It 
comes under precaution of electric shock.)
