Hearing Aid Compatibility in the US
In the US, specific hearing aid compatibility (HAC) performance ratings can help clarify how certain
wireless phones and hearing aids may perform together. HAC compliant wireless phones are
capable of working with hearing aids that have a minimal immunity rating of at least 2. The immunity
rating indicates how susceptible a hearing aid is to picking up interference from a digital wireless
phone. It can rate the performance of the hearing aid for either microphone and/or telecoil coupling.
Some hearing aids are more immune than others to this interference noise, and phones also vary in
the amount of interference they generate. The US performance rating system for HAC compliant
wireless phones is as follows:
The “M” (microphone) indicates that the product has been tested and rated for acoustic coupling.
The "T" (telecoil) represents that the product has been tested and rated for inductive coupling. The
higher the "M" or "T" rating, the less likely the hearing aid user will experience interference when the
hearing aid is set to the respective microphone or telecoil mode. The highest values to date are 3 and
4 (e.g., “M4” or “M3/T3”).
To determine if a product is rated for HAC, please look for the HAC rating or logo on the phone’s
packaging. For a list of current HAC models, visit
motorola.com/hacphones .
Results will vary depending on the user’s hearing aid and hearing loss. If your hearing aid 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. To couple
the device to your telecoil equipped hearing aid, switch your hearing aid to the “T” or telecoil setting.
Then, enable the ‘Hearing Aid’ mode feature on your Motorola phone with the following sequence:
Apps > Phone > Menu > Settings > Hearing aids.
Motorola Mobility hearing aid compatible phones have 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 phone that have not been tested yet for use with hearing aids. It is
important to try the different features of this phone thoroughly and in different locations, using your
hearing aid or cochlear implant, to determine if you hear any interfering noise. Contact your service
provider or Motorola for information on hearing aid compatibility. If you have questions about return
or exchange policies, contact your service provider or phone retailer.
