Enabling TTY
TTY (also known as a TDD or Text
Telephone) is a telecommunications device
that enables you to communicate by
telephone if you are deaf, hard of hearing,
or have speech or language disabilities.
Your device is compatible with select TTY
devices. You can connect a TTY/TDD
machine to your device through the
headset jack while this mode is enabled.
Please check with the manufacturer of your
TTY device for connectivity information and
to ensure that the TTY device supports
digital wireless transmission.

Turning on the HAC Setting
Do not turn on the Hearing Aid
CAUTION
Compatibility 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.
When the HAC (Hearing Aid Compatibility)
setting is on, your smartphone 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 car kit or headset.
HAC requires extra battery power, so watch
your battery consumption when it's turned
on.
