Adjusting the Camera
Refer to the Cisco TelePresence System 500 32" Assembly, Use & Care, and Field-Replaceable Unit
Guide on Cisco.com for complete camera management information.
Testing the Display
Different light sources and the amount of light in terms of lumens or watts produces different color
temperatures. These color temperatures are sometimes expressed using terms such as cool, warm, or
daylight, but can be expressed more precisely in kelvins (K) as a numeric value.
Note Cisco recommends that you use lighting with a color temperature of 4000 to 4100 K.
Tip In many cases, the color temperature is printed on the light bulb.
Note
If you are unable to determine 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.
Each time you change the setting and click Apply, the color temperature in the display changes. You
cannot see these changes until you enter loopback mode for the camera. See
“Verifying Speaker
Function” section on page 5-3 to enter loopback mode.
To adjust a display:
Step 1
Log in to the Cisco TelePresence System.
Step 2 Choose Troubleshooting > Hardware Setup.
Step 3
Click the Displays radio button. A test image appears.
Step 4 Click Start in the Testing box to start the adjustment process. The Current Color Temperature test screen
appears, as shown in
Figure 5-1 .
Note Each display in the meeting room should be showing a set of horizontal grey bars and that display's
relative position. The current color temperature setting is displayed.
