Setting Tty Mode - Motorola iDEN i80s User Manual

Setting TTY Mode

TTY Setup enables you to set your options for using your phone with a
teletypewriter (TTY) device. By default, your phone is set to function with a
TTY device in TTY mode.
Your phone supports the following TTY modes:
• TTY — for calls in which you type and read text on your TTY device.
• VCO (Voice-Carry-Over) — for calls in which you speak into your phone
and read text replies on your TTY device.
• HCO (Hearing-Carry-Over) — for calls in which you type text on your
TTY device on listen to voice replies on your phone's speaker.
You can set your TTY mode using your phone's Settings menu at any time, or
by issuing commands from your TTY device while on an active call.
To set your phone's TTY mode using your phone's Settings menu:
From the Initial Setup screen, press R to scroll to TTY Setup.

To set your phone's TTY mode from your TTY device, issue one of the
following commands while on an active call:
• "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 your phone's speaker volume, see "Alert
Timeout" on page 143.)
NOTE: TTY device manufacturer's proprietary feature 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.
