To Make a 1-Line VCO Call

  1. Dial your SVRS call at the Home screen.
  2. When the call is answered, the interpreter will see that you are making a VCO call. The interpreter will then call the hearing person. 
  3. When connected, you can speak to the person you called using your own voice. The audio picked up by the microphone in ntouch VP’s Remote Camera Unit (RCU) will be sent with the video signal. The interpreter will sign the hearing person’s part of the conversation to you.
  4. If you do not want to use VCO for any call, just tell the interpreter that you do not want to make a VCO call. The interpreter will not connect the voice call. Instead, the interpreter will place a regular SVRS call to the hearing number you dialed.
