Motorola Mobility LLC 222 W. Merchandise Mart Plaza, Chicago, IIlinois 60654, United States Tel: 847—687—6929 ; Fax: 954—337—2377 Declaration — MIF for HAC RF Interference Evaluation To whom it may concern: This device, with FCC ID: IHDTS6GXN2, Hearing Aid Compatibility Requirement is going to be certified under ANSI €63.19 2011 version per Part 20.19. For Radio Frequency Interference, Speag‘s Audio Interference Analyzer (AIA) 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. .
