§  76.1203   Incidence of harm.

   A multichannel video programming distributor may restrict the
   attachment or use of navigation devices with its system in those
   circumstances where electronic or physical harm would be caused by the
   attachment or operation of such devices or such devices that assist or
   are intended or designed to assist in the unauthorized receipt of
   service. Such restrictions may be accomplished by publishing and
   providing to subscribers standards and descriptions of devices that may
   not be used with or attached to its system. Such standards shall
   foreclose the attachment or use only of such devices as raise
   reasonable and legitimate concerns of electronic or physical harm or
   theft of service. In any situation where theft of service or harm
   occurs or is likely to occur, service may be discontinued.
