• The FCC has adopted HAC rules for digital
wireless phones. These rules require certain
phone to be tested and rated under the
American National Standard Institute (ANSI)
C63.19-2011 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 tele-coil 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 given on a scale from one
to four, where four is the most compatible.
Your phone meets the M3/T3 level rating.
