Samsung M575 User Manual page 81

To access the state Telecommunications Relay Service
(TRS) for assistance with TTY calls:
Dial 711, press
an operator.
Caution!: 911 Emergency Calling - it is recommended 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 software
used by PSAPs. This matter has been brought to the
attention of the FCC, and the wireless industr y and the
PSAP community are currently working to resolve this.
