Motorola Mobility LLC 222 W. Merchandise Mart Plaza, Chicago, lIlinois 60654, United States Tel: 847—687—6928 Declaration — MIF for HAC RF Interference Evaluation To whom it may concern: This device, with FCC ID: IHDT5GXN4, 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 aperation made for all air interfacesare pre—determined values provided by Speag. _ L ' a e °P . s 7 suunaloscoaicns , 1 10021 — GSM-FDD(TOMA,GSK) 363 10025 EDGE—FDD (TDMA, 8PSK, TN 0) 475 10480 UMTS—FDD(WCDMA, AMR) 2543 10225 — UMTS—FDD (HSPA+) —20.39 10081 o2 comeznoorprtmRes 4971 10295 CDMA2O00O(1xRTT,RC1 $03,/Bth Rete 25 fr.) a.26e 10403 : CDMAZOOO(EV—DO,Rev.0) ' 41681 10170 LTE—FDOD(SC—FDMA, 1RB,20MHz, 16—G0AM) ‘9.76 10172 \ —LTE—TDD (SC—FDMA, 1 RB, 20 MHz, QPSK) 62 10173 LTE—TDD (SC—FDMA, 1 RB, 20 MHz, 16—QAM) 4144 10174 LTE—TDD (SC—FDMA, 1 RB, 20 MHz, 64—9AM) — 154 10081 © IEEE 802.11b WiFI 2.4 GHz (DSSS, 11 Mbps) ©2.02 10077 IEEE 802. 119 WiFi 2.4 GHz (DSSSIOFDM; 54 Mbps) 0.12 10427 IEEE 802.11n (HT Greeneld, 150 Mops, 64—QAM) 21844 : 10089 1EEE 802.11@/h WiFi 5 GHz (OFDM, 54 Mbps) 345 10816 IEEE 802.1 fac WiFi (40MHz, MCSO, 90pe duty eycle) 567 We are confirming that the Speag simulation provided represents all the air interface modes applicable for a HAC rating for this handset.
