If you would like to make a call with Voice Carry Over (VCO and wish to receive the Baudot tone
back from or to the Relay Operator), you could use this feature of the PortaView Plus. In order to use
this feature you will need the help from the Relay agent. Follow this procedure to make a call.
1. Plug the external clip microphone to the MIC jack on the right side of the machine. Clip the
microphone to your shirt close with your mouth. If you prefer to use internal microphone, do
not plug the external microphone to the TDD.
2. Turn on the TDD machine.
3. The PortaView Plus is now ready to transfer your voice (or receive the voice from the caller).
Press [SHIFT] and [DIAL] at the same time. After you see the message. “TYPE NUMBER OR
A-Z:” type your state relay number.
4. Press [CTRL] and [V] at the same time. Release both keys. The display will read “VCO ON”
5. When the Relay Operator answers the call, you now may type the request to make the VCO call
to the operator. For example, in type, “I WANT TO MAKE A VCO CALL PLS GA”
6. When the operator is ready to receive voice, he or she will ask you to start voice. From now on,
you can use voice to communicate with the operator and the caller when receiving Baudot
answer on your screen.
7. To end the VCO call, press and hold [CTRL] and [9] at the same time until you see the message
on the screen. “DISCONNECTED”.
To make HCO call, instead of using microphone to talk you use the speaker to hear the caller voice
and type back to the operator.
NOTE: VCO and HCO feature are optional for your PortaView Plus. Please contact your Krow’s Representative to
have it installed.
