Chapter 9 First-Time Setup

Setting Up CTS Components

Step 2 From Troubleshooting, choose Hardware Setup to initially set up the components in the

Cisco TelePresence system. Cisco suggests that you set up CTS components in the following order:

•Setting Up the Displays, page 9-5

•Setting Up the Cameras, page 9-7

•Setting Up the Speakers, page 9-13

•Setting Up the Microphones, page 9-13

•Setting Up the Projector, page 9-15

•Other Devices, page 9-22

Setting Up the Displays

A display is set up correctly when the color on the display has been adjusted for the lighting in the meeting room. Each display must be set up individually.

•From the Hardware Setup page under Troubleshooting, click the Display radio button.

•Click Start to begin the adjustment process.

Each display in the meeting room should now be showing a set of horizontal grey bars and that display's relative position. Select the color temperature of the lighting in the meeting room and click Apply.

Selecting the Light Level

When adjusting the images on the display screens for the Cisco TelePresence system, you must take the color temperature of the ambient light in the room into consideration.

Sources of light in most rooms are either incandescent light bulbs that use tungsten filaments or fluorescent lights. Each of these light sources, and the amount of light in terms of lumens or watts, produces a different color temperature. This color temperature is sometimes expressed using terms such cool, warm, or daylight, but can be expressed more precisely in kelvins (K) as a numeric value.

Following are the temperatures that can be selected for adjusting the image on the Cisco TelePresence display screens:

•3500 K

•4000 to 4100 K (recommended setting)

•5000 K

•6500 K

•7500 K

In many cases, the color temperature is printed on the light bulb. If you are unable to ascertain the type and color temperature of light bulbs in the meeting room, experiment with color temperature settings until the color and images on the display screen look lifelike.
