TTY mode
A TTY (teletypewriter, also known as a TDD or Text Telephone) is a telecommunications device
that allows people who are deaf, hard of hearing, or who have speech or language disabilities,
to communicate by telephone.
Your phone is compatible with select TTY devices. Please check with the manufacturer of your
TTY device to ensure that it supports digital wireless transmission. Your phone and TTY device
will connect using a special cable that plugs into your phone's headset jack. If this cable was not
provided with your TTY device, contact your TTY device manufacturer to purchase the
connector cable.
To turn TTY mode on or off:
1.
From the Home screen, tap
2.
Tap TTY Full, TTY HCO, or TTY VCO to turn TTY mode on.
– or –
Tap TTY Off to turn TTY mode off.
NOTE: When enabled, TTY mode may impair the audio quality of non-TTY devices
connected to the headset jack.

It is recommended that TTY users make emergency calls by other means,
including Telecommunications Relay Services (TRS), analog cellular, and
landline communications. Wireless TTY calls to 911 may be corrupted
when received by public safety answering points (PSAPs), rendering
some communications unintelligible. The problem encountered appears
related to TTY equipment or software used by PSAPs. This matter has
been brought to the attention of the FCC, and the wireless industry and
the PSAP community are currently working to resolve this.
