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 Treo 700w smartphone is compatible with select TTY
devices. You can connect a TTY/TDD machine to your
smartphone through the headset jack, but you cannot use
your headset jack with a headset or hands-free kit 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 Verizon Wireless. Please contact
Verizon Wireless’s customer service department for more
information.

2. Select Personal, and then select Phone.
3. Select Phone.

mode, VCO mode, or HCO mode.
5. Press OK. A keyboard icon appears at the top of your
Today screen whenever TTY is enabled.
To disable TTY, repeat steps 1 and 2.
Hearing Aid Compatibility Compliance Hearing aid
compatibility ratings now appear on some handset
packages. If your handset has a hearing aid compatibility
rating of M3 or M4, then that handset has met or
surpassed the American National Standards Institute’s
(“ANSI”) hearing aid compatibility standard as adopted by
the Federal Communications Commission.
The handset’s M-rating along with a hearing aid’s M-rating
will assist customers in finding a handset that will work
best for them.
