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.
• However, hearing aid compatibility ratings
don't guarantee that interference to your
hearing aids won't happen. 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.
• This phone has been tested and rated for use
with hearing aids for some of the wireless
technologies that it uses. However, there may be
some newer wireless technologies used in this
