Do not install the unit in following places:

   In a place which is exposed to direct sunlight or near                     
   a source of heat such as a radiator.

   In a place where the heat cannot escape due to poor
   ventilation, or where it is very humid or dusty.

   In an unstable place with excessive vibrations or
   sloping.

  In a place which may be exposed to rain, such as
  near a window.

 

 In a place which may be exposed to soot, vapor or

  heat, such as near a cooking stove.

Connection precautions

  Be sure to switch off the powers of the related
  equipment before making any connection.

  The "White" input/output jacks of the amplifier are
  designed for the Left channel, while the "Red' jacks
  are for the Right channel. Be sure to connect the
  cords without mistaking the correspondences of the
  Left and Right channels.

  Insert the plugs of the connection cords securely into
  the jacks. If the connection is incomplete, sound may
  not be produced or noise may be generated.

  When unplugging the power cord from the power
  outlet, be sure to grasp the plastic molding of the 
  plug and pull.
