Turning on the HAC Setting
When the HAC setting is on, your device 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. Turn off the
Bluetooth feature. It does not affect calls heard on the speakerphone or with a car kit or
headset. HAC requires extra battery power, so watch your battery consumption when it's
turned on.
Caution:
1. Make sure your phone is turned on (see "Turning Your Device's Phone On and Off" on
page 17).
2. Press Phone
3. Press Menu
4. Select Options and then select Phone Preferences.
5. Check the Hearing Aid Compatibility box.
6. Select OK.

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.
