Motorola Mobility LLC 222 W. Merchandise Mart Plaza, Chicago, Illinois 60654, United States Tel: 847-687-6929 ; Fax: 954-337-2377 Declaration - MIF for HAC RF Interference Evaluation To whom it may concern: The device, with FCC ID: IHDT56XC3 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 (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. UID Communication System Name MIF(dB) 10021 GSM-FDD(TDMA,GMSK) 3.63 10460 UMTS-FDD(WCDMA, AMR) -25.43 10081 CDMA2000 (1xRTT, RC3) -19.71 10295 CDMA2000 (1xRTT, RC1 SO3, 1/8th Rate 25 fr.) 3.26 10170 LTE-FDD(SC-FDMA,1RB,20MHz,16-QAM) -9.76 We are confirming that the Speag simulation provided represents all the air interface modes applicable for a HAC rating for this handset.
