If your camera is not appearing in Zoom, Microsoft Teams, or other platforms:

1. Confirm the camera has power.
   
2. Check USB or HDMI connections.
   
3. Restart the room computer or conferencing appliance.
   
4. Verify the correct camera is selected in settings.
   

If the camera remains undetected, the control processor or USB extender may require service.

If participants cannot hear you:

• Confirm microphone is not muted.
  
• Check cable connections to DSP or mixer.
  
• Verify the correct microphone is selected in the meeting platform.
  
• Restart the conferencing system.
  

Ceiling microphones and beamforming arrays often require network connectivity.

If far-end audio is silent:

• Check amplifier or powered speaker status.
  
• Confirm correct audio output device is selected.
  
• Verify DSP routing is active.
  
• Reboot the room system.
  

Audio routing errors are common after system updates.

If you cannot join meetings:

• Confirm internet connectivity.
  
• Check firewall restrictions.
  
• Restart the conferencing appliance.
  
• Verify login credentials are active.
  

Account authentication sometimes expires and requires re-login.

If the conference room display is blank:

• Confirm input selection on the display.
  
• Check HDMI connections.
  
• Restart the room computer or appliance.
  
• Verify source device is powered on.
  

If using HDMI extenders, long cable runs may require service inspection.

Power interruptions can cause devices to boot improperly.

Recommended reboot sequence:

1. Reboot modem and router first.
   
2. Wait for full internet restoration.
   
3. Power on network switches.
   
4. Power on conferencing appliance.
   
5. Power on display and DSP last.
   

Sequence is critical in commercial AV environments.

Echo issues may be caused by:

• Improper DSP configuration
  
• Microphone placement
  
• Speaker volume levels
  
• Platform echo cancellation settings
  

Professional calibration may be required to eliminate persistent echo.

If the conference room control panel is unresponsive:

• Confirm PoE switch power.
  
• Reboot the control processor.
  
• Check network connectivity.
  

Most control panels rely on network-based communication.

This is typically caused by:

• Insufficient internet bandwidth
  
• Network congestion
  
• WiFi instability
  
• Camera resolution settings
  

Hardwired connections are recommended for conferencing systems.

Schedule service if:

• Conference room systems fail repeatedly
  
• DSP routing errors persist
  
• Cameras disconnect frequently
  
• Control panels go offline
  
• Multiple rooms experience similar issues
  

Commercial AV systems require stable networking and professional calibration.
