§  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
   Engineer in Charge (EIC) 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 EIC obtained.

   (c) When notified by the EIC 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 EIC may require the engineer making the
   investigation to furnish proof of his or her qualifications.
