Using Hearing Carry Over (HCO)
For people who can hear but are speech impaired, the Uniphone 1000 can

VCO. The caller types to the other person (or relay service CA) and
listens to the other person’s reply.

following display screen:

TEXT–TELEPHONE VCO on the display screen.

5. Continue to listen and type until your conversation is
finished.
6. When you are finished with your conversation, replace the handset
and hang up the Uniphone 1000 by pressing the key and the
key at the same time.
You do not have to put down the handset when you want to type. The
Uniphone 1000 automatically turns off the handset while you type.
