The FAA's summary their words, unchanged

These special conditions are issued to the de Havilland Aircraft Company of Canada for the de Havilland DHC-8-400 airplane. This airplane will utilize new avionics/electronic systems that provide critical data to the flightcrew. The applicable regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high-intensity radiated fields. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
