Closed User Group (Menu 9.3.7)
Closed user group is a network service that specifies the group of people
whom you can call and who can call you. For more information contact
your network operator or service provider. If a group index is specified, it
is used for all outgoing calls. If no group index is specified, the network
will use the preferential index (a specific index that is stored in the
network).

TTY (Menu 9.3.8) - Not Support
The majority of users are Deaf, but commonly, a TTY is also used by Hard
of Hearing, Speech Impaired, and even Deaf and Blind individuals. When
you use a TTY, only one person can type at a time, and you should not
interrupt the other. Keep your sentences short and right to the point. If at
all possible, have a printer to facilitate your life. Try to avoid asking too
many questions at once.
Send DTMF (Menu 9.3.9)
You can send the DTMF (dual tone multi-frequency) tones of the number
on the display during a call.
This option is helpful for entering a password or account number when you
call an automated system, like a banking service.
