To (6), (5), (4), digit numbers: Adds a
prefix to numbers that are only six, five,
or four numerals long. For example, if all
the phone numbers in your office have
the 408 area code and a 555 exchange,
followed by a 4-digit extension, select 4
and enter the prefix 408555. To call a
colleague, simply dial your colleague’s
4-digit extension; your Centro
automatically dials the rest and makes
the call. You can also create contact
entries with just the extension number
and then dial the number from your
Contacts list.

Using TTY
A TTY (also known as TDD or text
telephone) is a telecommunications device
that allows people who are deaf or hard of
hearing, or who have speech or language
disabilities, to communicate by telephone.
Your Centro is compatible with select TTY
devices. You can connect a TTY/TDD
machine to your Centro through the
headset jack, but you cannot use your
headset jack with a headset while this
mode is enabled. Please check with the
manufacturer of your TTY device for
connectivity information and to ensure that
the TTY device supports digital wireless
transmission.
To use TTY, you may need to make
additional arrangements with AT&T. Please
contact the AT&T customer service
department for more information.
