Tty Mode - LG Nexus 5 User Manual

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. Touch
>
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.
