IVS Trouble-shooting Guide

• What if the IVS System has no power?
• What if the touch screen won't respond?
• What if I can't hear the other site?
• What if the other end cannot hear me?
• What if there's an echo in the audio?
• What if the local system goes down?
• What if a remote site goes down?
• What if the computer will not appear on the US Monitor?
• What if I want chair control and it's already taken by another site?

• What if the IVS System has no power?
  • The main power and codec switches located inside the front of the main cart should be on, and the indicator lights should be on. (Note: leave the codec switch ON all the time.)
  • If the power switch indicators aren't lit, check that the main power cord is plugged into the wall outlet. There is also a circuit breaker on the side of the power strip in the rear of the cart. The power strip is located inside the hood that covers the rear of the cart.
    To remove the hood, carefully pull on it from the bottom and then from the top. Pull straight back so that you don't bend the hood. It is attached using four ball retainers which let it snap of easily. Place the hood in a safe place.
    Make sure the circuit breaker is pushed in. Also check that the codec power switch on the rear of the codec is in the UP position.

• What if the touch screen won't respond?
  • Check that the Radiance touch screen cable is securely connected to the cable marked Touch Panel on the back of the codec.
  • Call IT @8306 for permission to reboot the system. Then turn off the main power switch located in the main cabinet of the Them Monitor. Wait 10 seconds, turn the switch back on. The system will re-calibrate, which usually takes about 3 minutes.

• What if I can't hear the other site?
  • Make sure the other site's microphone is plugged in and placed for optimum sound pickup. The Mic Off button of the Main Menu of the touch screen should show the Mic icon without a slash.
  • If the Them Monitor has a message that reads "Audio-Receive Mute" and you can't hear the other site try shutting off the system by pressing the OFF button located on the main menu pad of the Touch Panel; then turn the system on again.
  • If the "Audio-Recieve Mute" message is still on your screen, call IT @ 8306 for permission to reboot. Then reboot the system by turning off the main power switch located in the main cabinet of the Them Monitor. Wait 10 seconds and turn the switch back on. The system will re-calibrate, which usually takes about 3 minutes.
  • If this does not work, call Information Technology (970) 947-8306

• What if the other end cannot hear you?
  • Check that your microphone is plugged in and placed for optimum sound pickup. The Mic Off button of the Main Menu of the touch screen should show the Mic icon without a slash.

• What if there's an echo in the audio?
  • For Tier 2 only, reset your Echo Canceler by pressing the Setup button on the Main Menu, then press Reset Echo Canceler. Remain quiet when you reset the echo canceler so it will model the room acoustics correctly.
  • If the Echo Canceler will not reset or you still hear an echo, try moving the microphones away from the speaker, located in the Them Monitor. The microphones should be a minimum of 3-4 feet from the monitor speakers.
  • If you still hear an echo, there is probably a site in the conference who has their mic turned on, but doesn't have any students. At that point, determine which site this is and call that site and ask them to mute their mic.
  • If none of these adjustments work, check the volume control on the monitor. The volume should always be adjusted on the Radiance touch screen, and not on the monitor. The monitor volume should always be set to 80% of the maximum volume.

• What if the local system goes down?
  • Call IT @ 8306 for permission to Reboot the system. Then do this by turning off the main power switch located in the main cabinet of the Them Monitor. Turn off the switch, wiat 10 seconds, turn the switch back on. The system will re-calibrate, which usually takes about 3 minutes.
  • There's a possibility that the phone line went down; this will take a day to fix. It is also possible that a major malfunction occurred in your hardware in which case a technician will be needed. Call the sites who are connected to the conference, explain the situation and use your backup class plan. (Other site phone numbers)

• What if a remote site goes down?
  • Call Information Technology (IT) at the District Office. (8306) It is possible that the site was dropped from the conference; this can be fixed immediately.
  • Get permission from IT to call the site and see if someone is available to reboot the system. Then reboot the system by turning off the main power switch located in the main cabinet of the Them Monitor. Turn off the switch, wait 10 seconds, turn the switch back on. The system will re-calibrate, which usually takes about 3 minutes.
  • If it is evident that the remote site cannot be brought back into the conference, call the remote site and tell them you will video tape the class for them.

• What if the computer will not appear on the Us Monitor?
  • Make sure the power on the Scan Converter (green power light should be on), the Computer and the ELMO Document Camera is on.
  • Check to see your View is set to Them & Us.
  • Make sure the source you selected on the Main Menu is Doc Cam, and the input select on the front of the Elmo is either set to Input 1 or Input 2, depending on which one the Scan Converter is connected to.
  • Refer to the diagram "Computer Scan Converter Connections via the Elmo" (in the IVS manual) to make sure the equipment is connected properly.

• What if I want chair control and it is already taken by another site?
  • Ask the sites present if anyone has chair control and if they would relinquish it. They need to enter the MCU menu, and make sure the Chair Control Icon has a slash through it.
  • If no present site has chair control, call I.T. and ask them to drop the sites not currently in the conference.
