HAC Mode

When HAC mode is active, your phone sends the audio signals from your
phone to the telecoil rather than to the microphone of your hearing aid.
The HAC setting only improves the quality of sound transmitted through
the earpiece; it does not affect the speakerphone or a headset.
• It is recommended that you disable Bluetooth functionality when HAC
mode is in use.
• HAC mode consumes additional battery power. Pay close attention to
the battery’s charge level when using HAC mode.
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.
