Declaration - MIF for HAC RF Interference Evaluation

This device, with FCC ID: UZ7TC57HO, 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.
