2. Preparing the Document Camera for an Event
The following steps will help prepare the Document Camera for use
Ensure that the Document Camera is connected: The Document Camera should
already be connected to the videoconference system. Before using the camera,
check to ensure that all of the cables are properly connected:
Polycom iDoc: Connect the cable to the EXT. port located on the back of the
iDoc system.
Polycom Room-Based System: Connect the cable to the S- Video port on the
back of a Polycom system.
Tandberg Intern II: Connect the cable to the S-Video port located on the front
panel of the Tandberg Intern II.
Connect to power: Connect the A/C power cable to the power outlet on the wall.
Ensure that the power plug is firmly pushed into the power port at the back of the
Document Camera.
For those using a Polycom iDoc or Tandberg Intern II system,
remember to use an alternative power outlet located on the wall of the
room – DO NOT use the power bar on the videoconference system
itself.
Turn on the Document Camera: Turn the Document Camera on by
toggling the power switch located on the rear right hand corner of
the Document Camera.
Position the Main Column and Lighting Unit Arms: The
next step is to set up the camera for use. This involves
setting up the main camera column and lighting unit
arms.
To release the camera column arm, press the lock
button located at the rear left side of the Document
Camera and raise the camera head. Next, unfold the
lighting unit arms so that they are positioned as in
the diagram on the previous page.
To store the Document Camera, turn off the power
switch and unplug the unit from the wall outlet. Turn
the camera head so that it may be ready to be stored
with the camera eye facing forward. Press the
column lock release button and fold down the main
column. Fold down the lighting unit arms – right side
folds down first.

conditions. To adjust the white balance of the camera:
With the stage surface clear of material, press the
WHITE BALANCE button on the front panel.

white balance buttons are located on the camera head.
Switching to the Document Camera view: Switch from the main videoconference
camera to the Document Camera by selecting the input device using the
videoconference system remote control. For single monitor systems, you will need
to switch the PiP view.
iDoc Systems: Push the Camera button to bring the three input icons
onscreen. Use the arrow keys to select the #2 (Document Camera) icon and
press Select to ready the monitor to receive input from the Document Camera.
Make sure that the switchbox located at the side of the iDoc has been set to
“Document Camera”.
