T-Ratings: Phones rated 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 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. 
Turning on the HAC Setting 
When the HAC setting is on, your Adamant
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 with a headset. HAC requires extra 
battery power, so watch your battery consumption when 
it's turned on.
