CI-ODC-1-B QUICK REFERENCE GUIDE
The Tech Works CI-ODC-1-B Operator Desk Console is part of the Collaborative Intercom product
group. The Console includes a professional cardioid, condenser, gooseneck microphone, and a speaker.

to talk, and collaborate hands free. A headset jack on the side of the console allows connection of a local
operator headset such as the Plantronics wireless unit.
