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 www.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 phone with the

following sequence: Phone > Menu > Settings > Calls > Hearing aids.
