Merchandise Mart Plaza, Chicago, Iflinois 60654, United States Tel: 847—687—6928 Declaration — MIF for HAC RF Interference Evaluation To whom it may concern: This device, with FCC ID: IHDT5GXQ3, 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 ib : Communicalion System Name | MIECGB) GSM—FDD{TDMA,GMSK) 10025 EDGE—FDD (TDMA, 8PSK, TN 0) 3.75 10460 UMTS—FDD(WCDMA, AMR) 2543 102256 UMTS—FDD (HSPA+) —20.39 10170 LTE—FOD(SC—FDMA, 1RB,20MHz,16—QAM) —9.76 10061 IEEE 802. 11b WiFi 2.4 GHz (DSSS, 11 Mbps) —2.02 10077 1EEE 802. 119 WiFI 2.4 GHz (DSSS/OFDM, 54 Mbps) 0.12 10427 IEEE 802.11n (HT Greeneld, 150 Mbps, 64—QAM) 1344 We are confirming that the Speag simulation provided represents all the air interface modes applicable for a HAC rating for this handset.
