  1. There are two ways to enable VCO Plus
    • You can tell the video interpreter when making a call that this is a VCO call OR
    • Go to “My Contacts” and click the name of the contact, then click the button to choose “Voice Carry Over (VCO).” The video interpreter will now know it’s a VCO call when you call this contact.

  2. When making the call, you can speak into the handset or microphone/speakerphone, and the video interpreter will interpret the dialogue from the hearing person.
  • Praise the Z products, Love it!
