The PowerMic, stored in the system WorldCart storage drawer, is a domed, circular microphone that picks up and transmits the sounds at your site to the remote sites.

Place the PowerMic in the center of your conference table. Position it at least 8 feet from the speaker built into the system WorldCart to avoid audio feedback. And to help people avoid tripping over the wire connecting the microphone with the system WorldCart, place a piece of carpeting or other covering over the wire as it runs across the floor.

The Main Camera sits on top of the System Monitor. As controlled by buttons on the Keypad, it moves up and down, from side to side, and zooms in and out to change the image that the camera is receiving and transmitting to the remote sites. (Note: Your camera may look slightly different from the one pictured here.)

The "preset" buttons on the Keypad allow you to preprogram as many as four specific camera views and select them at will.

Presetting the Look-At-Me Button also draws the camera to a specific view, showing the presenter or meeting leader.

The Second/Graphics Monitor, also looking like a television set, is available for displaying and images for the local audience from the supporting audio/visual equipment—the Document Camera, Slide Projector, VCR, and computer screen.

Your equipment includes two WorldCarts, one supporting the System Monitor and the Main Camera, the other supporting the Second/Graphics Monitor.

The central section marked with the PictureTel logo houses the speaker that broadcasts sound from remote sites.

The lower portion of the cart is a cabinet containing a pull-out storage drawer and additional storage space. The drawer in the cabinet under the System Monitor provides storage for the PowerMic, Keypad, and Look-At-Me Button. Below the storage drawer is a shelf for the VCR. The Codec, the system’s electronics module, is on the bottom shelf, accessible through the back of this WorldCart.

"Codec" s short for "Coder-Decoder." The Codec is the unit at the bottom of the system WorldCart that contains the system’s electronics, software, and power supply. The Codec’s back panel, accessible through the back of the WorldCart, displays the jacks for cables connecting the system with audio and video inputs and outputs.

The System Monitor, which looks like a television set, displays the images transmitted by remote sites. As controlled by a button on the Keypad, it will also display a Picture in a Picture (PIP), a window in the lower right corner of the screen showing the images you’re sending from your own site.

The WorldCart supporting the System Monitor is also termed the "system WorldCart."

The Keypad is the remote control you use for adjusting the volume of sound you hear coming from remote sites; choosing the source of the video signal (Main Camera, Document Camera, Computer Scan Converter, Slide Projector, VCR, or satellite) you’re sending; and preprogramming and changing the Main Camera’s view.

You can place the Keypad as much as 50 feet from the system WorldCart. Because it works with a multidirectional signal, you don’t have to point the Keypad directly at the WorldCart when you press the control buttons.

The buttons in the upper right section of the Keypad control the images you’re receiving from the remote ("far end") site if that site allows such an option. You’ll rarely, if ever, need to use the buttons in this section, though. You’ll usually be concerned with the buttons in the lower right section of the Keypad that control the images you’re sending from your location, the "near end" site.

8 - Main Camera (MAIN) - Chooses the Main Camera as the video source. "Preview" displays the images captured by the Main Camera on your second/graphics monitor and "Send" lets the far end sites see those images as well.

9 - Document Camera (DOC) - Chooses the Document Camera. "Preview" displays the image captured by the Document Camera on your second/graphics monitor and "Send" lets the far end sites see that image as well.

10 & 11 - Auxiliary Input A (AUX A) and Auxiliary Input B (AUX B) - These two buttons are provided for additional inputs such as a laptop computer presentation, another camera, a video slide projector, or any device which can send a common video output. The "Preview" and "Send" buttons work in the same way as for other video sources.

12 - Videocassette Recorder (VCR) - Chooses the VCR. "Preview" displays the images generated by the VCR on your second/graphics monitor and "Send" lets the far end sites see those images as well.

Note: The video inputs (buttons 8 - 12) have two rows of buttons, a row of smaller "Preview" buttons on the bottom and a row of larger "Send" buttons on the top.

The plain "Preview" buttons on the bottom row select a video input or source and sends that video signal to your second graphics monitor but does not send the picture to the far end sites. Use the "Preview" buttons to view a video source at your site only, and to preview an image before you broadcast it to the far sites.

The "Send" buttons on the top row, each sporting a graphic symbol, choose the video source you wish to view and also send as live video to the far end sites.

1 - Audio Mute - Mutes your site’s microphones. When this feature is on, a message will appear on the system monitor [Mute: Near End]. This feature enables you to have private conversations without being heard by the far end sites involved in the conference.

2 - Volume Control - Raises and lowers the volume of the sound you hear coming out of your system’s speaker from the far end sites. (This button does not control the volume of the sound you send to the far end sites. Your system is equipped with highly sensitive automatic gain microphones. The only way to increase the volume of the sound you are sending from your site is to move closer to the microphone.)

3 - Picture in a Picture (PIP) - This button toggles on/off the display of the PIP in the lower right hand corner of the system monitor. The PIP is provided as visual feedback so you can see the live video signal you are sending to the far end sites from your location. When you wish to display slides or a computer-based presentation on the monitor, though, you may wish to turn the PIP off so that the full screen is available to show the images.

4 - Camera Position - The camera positioning button points and aims the system camera. The camera is equipped with 180 degree pan (side-to-side) and 90 degree tilt (up-and-down) capability.

5 - Camera Zoom - The upper portion of this rocker arm button zooms the camera in, and the bottom portion zooms the camera out.

6 - Camera Preset Buttons - The keypad is equipped with camera preset buttons to store up to four predefined camera positions. The procedure is as follows: 1) point and zoom the camera to show the desired location, 2) press the small "Set" button, and 3) press one of the four the preset buttons (labeled on the keypad as 1, 2, 3 and "Show Room") to store the position. Preset the Look-At-Me Button (LAMB) in the same way.

7 - Send Snapshot - A snapshot is a frozen still image that can be sent to the far end sites and displayed on their second or graphics monitor. This feature captures a still "frame" of whatever live video signal you are sending at the time and sends it to the far end sites.
