Ctia Requirements - Zte Z988 User Manual

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.
