T3 or T4 meet FCC requirements and are likely to be
more usable with a hearing device’s telecoil (“T Switch”
or “Telephone Switch”) than unrated phones. T4 is the
better/higher of the two ratings. (Note that not all hearing
devices contain telecoils.) The more immune your hearing
aid device is, the less likely you are to experience
interference noise from your wireless phone. Hearing aid
devices should have ratings similar to those of phones.
Ask your hearing health-care professional for the rating
of your hearing aid.
Hearing devices may also be measured for immunity to
this type of interference. Your hearing device manufacturer
or hearing health professional may help you find results
for your hearing device.
For additional information about the FCC's actions with
regard to hearing aid compatible wireless devices and
other steps the FCC has taken to ensure that individuals
with disabilities have access to telecommunications
services, please go to www.fcc.gov/cgb/dro.
Turn on the HAC Setting
When the HAC setting is on, your Salute
TM
sends the audio
from your phone calls to the telecoil rather than to the
microphone of your hearing aid. You are likely to hear calls
much better because volume is increased and background
noise and feedback are diminished. The HAC setting
improves only the calls you listen to through the earpiece.
It does not affect calls heard on the speakerphone or a
headset. It’s better to turn off the Bluetooth function when
the HAC setting is on. HAC requires extra battery power,
so watch your battery consumption when it's turned on.
