Hearing Aid Compatibility Information
(HAC)
Your device is compliant with the FCC Hearing Aid
Compatibility (HAC) requirements. The FCC has
adopted HAC rules for digital wireless phones. These
rule require certain phone to be tested and rated under
the American National Standard Institute (ANSI)
C63.19 hearing aid compatibility standards. The ANSI
standard for hearing aid compatibility contains two
types of ratings:
M-Ratings: Rating for less radio frequency interference
to enable acoustic coupling with hearing aids.
T-Ratings: Rating for inductive coupling with hearing
aids in telecoil mode.
Not all phones have been rated, a phone is considered
hearing aid compatible under FCC rules if it is rated M3
or M4 for acoustic coupling and T3 or T4 for inductive
coupling. These ratings are not guarantees. Results
will vary, depending on the level of immunity of your
hearing device and the degree of your hearing loss. If
your hearing device happens to be vulnerable to
interference, you may not be able to use a rated phone
successfully. Trying out the phone with your hearing
device is the best way to evaluate it for your personal
needs.
