              Declaration — MIF for HAC RF Interference Evaluation
To whom it may concern:

This device, with FCC ID: MSQZO1Q0D, 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.
