Features for the Hearing Impaired

TTY device features such as Turbo-Code,

High-Speed, and Interruption are not supported by

your phone. These features must be turned off or

disabled to use your TTY device with your phone.

Turning On the TTY Feature

Your phone’s TTY feature must be on if you want

to make TTY calls, set the TTY mode, or change

the TTY baud rate. To make sure the TTY feature

is on:

From the main menu, select Settings > Phone

Calls > TTY > Use TTY. This field must say On.

Choosing a Mode

Your phone supports these TTY modes:

•TTY — You type and read text on your TTY

device.

•VCO (Voice-Carry-Over) — You speak into your

phone and read text replies on your TTY device.

• HCO (Hearing-Carry-Over) — You type text on

your TTY device and listen to voice replies on

your phone speaker.

To change mode while not in a call:

1 From the main menu, select Settings > Phone

Calls > TTY > Type.

2 Select the TTY mode you want.

When you make a TTY call, the call begins in the

TTY mode you last selected.

To change mode during a call using your phone:

1 Press m.

2 Select In Call Setup > TTY > Type.

3 Select the mode you want.

To change mode during a call using your TTY

device, issue one of the following commands:

• “VCO please” — to select VCO mode

• “HCO please” — to select HCO mode

• “HCO off please” — to turn off HCO mode

Important: When you are using HCO, the sound

coming from your phone speaker may

be uncomfortably loud. Use caution

when putting the phone to your ear.

(For information on setting the volume

of your phone speaker, see “Setting the

Volume” on page 150.)

Changing the TTY Baud Rate

By default, your phone’s TTY baud rate is set to

45.45, the baud rate required for TTY calls within

the U.S. To make calls outside the U.S., set your

TTY baud rate to 50.00.
