Turning on the HAC Setting 
To turn on the HAC function, touch the Home Key > Menu Key > Settings > Call settings 
and tick the Hearing aids check box. For detailed information, refer to “Using Your Phone 
With a Hearing Aid Device” on page 82.   
This section applies to T-Rating only and hearing aids that contain telecoils. When the HAC 
setting is on, your T-Mobile
®
 Concord™ 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 speaker or with a headset. HAC requires extra battery power, so 
watch your battery consumption when it's turned on. 
CAUTION: Do not turn on the HAC setting unless you use a hearing aid with a telecoil. 
Using this setting without a hearing aid or with a hearing aid without a telecoil may be 
harmful to your hearing. 
Distraction 
Driving 
Full attention must be given to driving at all times in order to reduce the risk of an 
accident. Using a phone while driving (even with a hands free kit) can cause distraction 
and lead to an accident. You must comply with local laws and regulations restricting the 
use of wireless devices while driving. 
Operating Machinery 
Full attention must be given to operating the machinery in order to reduce the risk of 
an accident.
