CI-ODC-1 QUICK REFERENCE GUIDE
The Tech Works CI-ODC-1 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
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
There are two Operational Configurations
VOX (Voice Activated), or Push-to-Talk, Microphone
The user should read the section below that pertains to their configuration
VOX (Voice Activated Microphone) Operation (Standard Option):
Basic Console Operation is straightforward and intuitive
When the Operator wants to converse with the Procedure Room
The "LISTEN" switch is pushed, the indicator lights Red
If the Operator wants to end the conversation, the "LISTEN" switch is pushed again, the indicator goes off
The Operator may disable the microphone with the "TALK” Switch", to only listen to the Procedure Room
When the “TALK” switch is pushed, the indicator goes off to indicate the Console Microphone is disabled
When the “TALK” switch is pushed again, the indicator lights red, to indicate the Microphone is enabled
When the microphone is enabled, the Switchover is Voice Activated (VOX)
The Operator must speak directly into the Console Microphone
At a distance of ~6” for proper response
The "LIMIT/VOX" indicator lights Green to indicate the VOX is tripped
During normal operation, the "LEVEL/VOX" Indicator flashes Red to indicate proper microphone level
If the Operator wants to continue listening without talking
the Microphone should be disabled (Push the “TALK” Switch again)
TALK may only be changed while listening
When listening is discontinued the state of TALK is retained
This allows the Listen Switch to Control both Listening and Talking
Push-to-Talk Microphone Operation, (Jumper Option):

The "LISTEN" switch is pushed, the indicator lights Red
If the Operator wants to end the conversation, the "LISTEN" switch is pushed again, the indicator goes off
