Motorola L7c ユーザーズマニュアル

A TTY (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 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 Sprint service, please call Sprint 
Customer Service via the state Telecommunications Relay 
Service (TRS) by first dialing 

771S

. Then provide the 

state TRS with this number: 866-727-4889.

(If you select Disable, press Disable [left softkey] after

In TTY Mode, 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.
