TTY Use With PCS Service From Sprint
A TTY (also known as a TDD or Text Telephone), is a telecom-
munications device that allows people who are deaf or 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 via 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.
When establishing your PCS Service, please call PCS Customer
Solutions via the state Telecommunications Relay Service (TRS) by
first dialing
. Then provide the state TRS with this
number: 866-727-4889.
To turn TTY Mode on or off:
1. Press . (A brief explanation of
TTY Mode will display.)
2. Press again to continue.
3. Press the navigation key up or down to select Enable TTY or
Disable TTY and press
.
Note: In TTY Mode when your headset is plugged in, your phone will display
the TTY access icon.
If TTY mode is enabled, the audio quality of non-TTY devices connected
to the headset jack may be impaired.
IMPORTANT
NOTICE:
911 Emergency Calling
Sprint recommends that TTY users make emergency calls by
other means, including Telecommunications Relay Services
(TRS), analog cellular, and land line 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
PSAP community are currently working to resolve this.
