Hearing Aid Compliance
Levels of Functionality
Viaero Wireless offers a variety of HAC phone models to meet the needs of wireless users with hearing disabilities. The mobile units are presented here by category. If a unit is not HAC compatible, it will be listed as N/A in the HAC Rating column.
- The first category is Basic Phones. These phones may or may not have features such as a camera, internet access, multimedia player or expandable memory with key functions of calling and messaging
- The second category is Smart Phones. These phones have advanced features such as a camera, Bluetooth, some desktop functions, e-mail and Internet access.
These 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. Consult your service provider or the manufacturer of this phone for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your service provider or phone retailer.
The Federal Communications Commission (FCC) defines Hearing Aid Compatibility (HAC) for wireless devices in terms of radio-frequency (RF) emissions and telecoil coupling. Cell phones are tested to see if they comply with the FCC's definition of hearing aid compatibility.
"M" refers to the RF emissions level of the handset device, and means the device is intended for use with hearing aids in microphone mode. The higher the "M" rating number on the device, the more likely the device can be used with a hearing aid on the microphone setting.
"T" refers to the device's telecoil coupling ability, and means the device is intended for use with hearing aids in telecoil mode. The higher the "T" rating number on the device, the more likely the device can be used with a hearing aid on the telecoil setting.
A telecoil is a small device that is built into some hearing aids for use with the telephone as well as assistive listening devices. To use the telecoil, generally either the hearing aid is switched to the "T" position or a button on the hearing aid is pushed to select the telecoil program. Some newer hearing aids will automatically switch to telecoil mode when using a phone. The telecoil picks up magnetic fields generated by telephones and converts these fields into sound. Telecoils are particularly useful for telephone communication because they permit the volume control of a hearing aid to be turned up without creating feedback or "whistling," and background noise can be reduced especially when using cell phones in noisy places. A hearing health professional can determine whether a hearing aid contains a telecoil and how it is activated.
