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. Tap > touch and hold
2. Touch TTY Full, TTY HCO, or TTY VCO to turn TTY mode on.
– or –
Touch 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.
Warning: 9-1-1 Emergency Calling
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 9-1-1 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.
