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: IHDT56XP1 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. __ Communication 'Srysteihr,t}lémei __ [ MIE(GB) : 10021 GSM—FDD(TDMA,GMSK) ' 3.63 10025 EDGE—FDD (TDMA, 8PSK, TN 0) 3.15 10460 UMTS—FDD(WCDMA, AMR) . —2543 10225 UMTS—FDD (HSPA+) : —20,39 10081 CDMA2000 (1xRTT, RC3) ~19.71 10295 CDMA2000 (1xRTT, RC1.$03, 1/8th Rate 25 fr.) 3.26 10403 CDMA2000 (1xEV—DO, Rev. 0) ~17.67 10170 LTE—FDD({(SC—FDMA, 1RB,20MHz,16—QAM) —9.76 10172 LTE—TDD (SC—FDMA, 1 RB, 20 MHz, QPSK) —~1.62 10173 LTE—TDD (SC—FDMA, 1 RB, 20 MHz, 16—QAM) ~1.44 10061 IEEE 802.11b WiFi 2.4 GHz (DSSS, 11 Mbps) —2.02 10077 [EEE 802.11g WiFi 2.4 GHz (DSSS/OFDM, 54 Mbps) 0.12 10427 IEEE 802.1 4n (HT Greeneld, 150 Mbps, 64—QAM) —13.44 10069 . {EEE 802.11a/h WiFi 5 GHz (OFDM, 54 Mbps) —3.15 We are confirming that the Speag simulation provided represents all the air interface modes applicable for a HAC rating for this handset.
