QUICK REFERENCE GUIDE
The Tech Works CI-ODC-4 Operator Desk Console is part of the Collaborative Intercom product
group. The Console includes a professional cardioid, condenser, gooseneck microphone, and a speaker.
Buttons and indicators provide control to allow the operator to just listen to the CI-Buss communication or
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 CS-540 wireless unit.

The Console Speaker listening level may be adjusted to be heard throughout the room
When the Console Microphone is enabled the Console Speaker listening level is reduced to a
lower level to prevent feedback
If there is a Remote Call Switch in the Procedure Room to get the attention of the Operator,
The Call Tone comes through the Console Speaker, only if the Console Microphone is not enabled
If the Procedure Room is in a Conversation with the Operator, it is assumed the Call Switch will not be
used
