§ 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.
