Troubleshooting
The following sections describe symptoms, possible causes, and potential solutions for common problems you may encounter with your Avaya system.
When experiencing a problem, visually inspect the unit. Ensure the system has not been exposed to water or heat sources or appears physically damaged.
Improperly connected or loose cables are common causes of problems with hardware units. When investigating a system problem, first inspect all the external controls and cable connections. Ensure that connections are correct and secure, and that nothing is obstructing the cables. Contact your administrator for information about proper cabling.
Adjusting Room Lighting
You can assist the system to maintain the best possible image quality by altering the environmental lighting and background colors of your environment. If light levels are too low you may consider adding artificial lighting. Indirect light from shaded sources or reflected light from pale walls often produces excellent results.
Avoid the following:
•direct sunlight on the subject matter, the background, or the camera lens which creates harsh contrasts
•direct illumination of the subject matter and camera lens
•colored lighting
•harsh side lighting or strong light from above
You can also improve dim scenes by adjusting the camera brightness. Refer to “Adjusting Camera Brightness” on page 31.
