§ 18.115   Elimination and investigation of harmful interference.

   (a) The operator of ISM equipment that causes harmful interference to
   radio services shall promptly take appropriate measures to correct the
   problem.

   (b) If the operator of ISM equipment is notified by the Commission's
   Regional Director that operation of such equipment is endangering the
   functioning of a radionavigation or safety service, the operator shall
   immediately cease operating the equipment. Operation may be resumed on
   a temporary basis only for the purpose of eliminating the harmful
   interference. Operation may be resumed on a regular basis only after
   the harmful interference has been eliminated and approval from the
   Regional Director obtained.

   (c) When notified by the Regional Director that a particular
   installation is causing harmful interference, the operator or
   manufacturer shall arrange for an engineer skilled in techniques of
   interference measurement and control to make an investigation to ensure
   that the harmful interference has been eliminated. The Regional
   Director may require the engineer making the investigation to furnish
   proof of his or her qualifications.
