   ASSEMBLING OR WIRING

  There are parts which use the insulation
  material such as a tube or tape for safety, or
  which are assembled in the condition that
  these do not contact with the printed board.
  The inside wiring is designed not to get closer
  to the pyrogenic parts and high voltage parts.
  Therefore, put these parts in the original
  positions.
