Direct VCO calls are easiest when both parties have a Ultratec Uniphone, which
is specifically designed for VCO calling. Even if they don't have an Ultratec
Uniphone, people can still make direct VCO calls, as long as both parties have a
TTY and a standard telephone handy.
Making a direct VCO call with the
Ultratec Uniphone 1140:
-
Press the Dial key and type in the phone number for the person you
are calling.
(The Ultratec Uniphone 1140 lets you speed-dial the number if you have it saved
in the directory.)
-
Watch the Ultratec Uniphone display to see if the call is ringing or busy.
-
When the person you are calling answers, pick up the Ultratec Uniphone handset
and press the <MENU>+<V> keys to send a VCO request. You will
see "VCO PLEASE GA" on your Ultratec Uniphone display. (If you are using
a different TTY, simply type your request for using VCO).
-
When the other person sees your request on their Ultratec Uniphone or TTY display
screen, they will know to pick up the handset to listen.
-
From this point, you can talk directly to the person on the other end.
They will hear your exact words. When you are finished talking, remember
to say "GA" or give some indication that it is the other person's
turn.
-
The other person can type their response on the Ultratec Uniphone (or other
TTY) keyboard. You will see their words appear on your display. In this
manner, you can talk directly to them and read their reply, privately and
naturally.
You can also make VCO calls through a Telecommunications Relay Service.
