The PPA T46 is FCC Part 15 compliant. Effective July 11, 2016, the FCC has mandated tighter emissions limits on auditory assistance transmitters (72-76 MHz) manufactured or imported after this date to help avoid interference with and/or degradation of other airborne signals (All products manufactured prior to July 11, 2016, are compliant). Williams Sound FM transmitters – PPA T46, PPA T27 and PPA T45 (all models) – all have received a Grant of Certification from the FCC and are fully compliant/approved under this new mandate.
