Motorola Mobility LLC Motorola Mobility LLC, 222 W. Merchandise Mart Plaza, Chicago, Illinois 60654, United States Tel: 847—687—6929 Declaration — MIF for HAC RF Interference Evaluation To whom it may concern: This device, with FCC ID: IHDT56YA3, FCC ID: IHDT5S6YA2 , FCC ID: IHDTS6GYA1 Hearing Aid Compatibility Requirement is going to be certified under ANSI C63.19 2011 version per Part 20.19. For Radio Frequency Interference, Speag‘s Audio Interference Analyzer (AlIA) or other indirect or direct measurement was not used to determine the M rating. The M rating was determined by measuring the maximum steady state average E—field values in dB (V/m) or average antenna input power as documented in HAC test report exhibit, and adding the MIF value in dB. The MIF values below for the worst—case operation mode for all air interfaces are pre—determined values provided by Speag.
