         The optic cables must be handled carefully so as not to distort the signal.  | 
      ||
| • | 
        It is extremely important that the two leads in the connector are not mixed up.
         | 
      |
| • | 
        The cables cannot be spliced.
         | 
      |
| • | 
        The lead must not be bent to form a curve with a radius of less than 25 mm.
         | 
      |
| • | 
        The lead must not be subjected to temperatures greater than 185°F (85°C).
         | 
      |
| • | 
        The lead ends should be kept free from dirt.
         | 
      |
| • | 
        The lead must not be subjected to blows that could cause the transparent plastic to whiten, thereby reducing light intensity. This could cause disruptions in communication.
         | 
      |
| • | 
        The lead should not be stretched across a sharp edge, which would cause increased damping of the signal.
