b. Sound:

Problem: There is no sound, or the sound is too soft/loud.
One or more volume dials on the amplifier may be turned down/up. The A-506A amplifier is located on the bottom shelf inside the computer cabinet. It has several volume dials. Some of the dials have a labeled mark indicating the recommended volume level. Make sure that the dial labeled “Master Volume” is set at the recommended volume level.

Problem: There is still no sound.
Make sure that the amplifier is on. The A-506A amplifier is located on the bottom shelf inside the computer cabinet. Find the power button on its right side. Above the power button is a red indicator light. If the light is lit, then the amplifier is on. If the light is not lit, then press the power button to turn the amplifier on.

Problem: The amplifier did not come on so there is still no sound.

If the checkbox named “Mute all” is checked, then uncheck it.
3. If any of the other sliders are all the way down or mute checkboxes are checked, then try adjusting the sliders or unchecking the checkboxes.
4. Close the Play Control window.
If the problem persists, report it to the TCB Helpdesk located in Sanford 304 or by phone at 542-6799.

c. Projector:

Problem: The projector does not show anything.
Make sure that the projector is on. Point the Sharp remote at the projector and press the On button. If the two lights on the front of the projector are green, then the projector is on. If the projector will not come on, then report this problem to the TCB Helpdesk located in Sanford 304 or by phone at 542-6799.

Problem: The projector still does not show anything.
Make sure that the Main Computer/Laptop switchbox is set to “Main Computer”. The Main Computer/Laptop switchbox is located on the bottom shelf inside the computer cabinet. Switch it to the “A” or “Main Computer” position, if it is not already.

Problem: The projector shuts down unexpectedly and without warning.
The projector may have overheated. In this case it will automatically shut down until it cools off. It will take at least five minutes for the projector to cool sufficiently. The projector will automatically come on again once it has finished cooling. If the projector does not come back on after 10 minutes, then the problem is not overheating. The projector’s motherboard might have failed. Report this problem to the TCB Helpdesk located in Sanford 304 or by phone at 542-6799.

B. Using the VCR for presenting a taped program:

Preview the taped program if it was recorded on any VCR other than those in the TCB classrooms before you attempt to present it to an audience. All the VCRs in the TCB classrooms are the same kind so that they all have the same tracking settings. An outside VCR’s tracking settings may be different. The VCRs in the TCB classrooms will try to automatically adjust to the tape’s tracking setting, but sometimes the VCR may be unable to do this. In this case the taped program will appear jittery, shaky, or unstable. The TCB Helpdesk can preview the taped program for you, or you can do so by going to an unused classroom.
Unlock and open the computer cabinet.
Lower the projection screen.
Turn the ceiling-mounted projector on with the gray Sharp projector remote. The Sharp remote should be inside the computer cabinet. Point the Sharp remote at the ceiling mounted projector and press the On button. It will take up to 30 seconds for the projector to warm-up to full intensity.

Insert your videocassette into the VCR. The VCR will not play the tape automatically. Do not put non-VHS tapes into the VCR even if you have an adapter.
The basic functions of the VCR are controlled with the buttons on the front panel of the VCR or with the black VCR remote. Press the Play button on the front panel of the VCR or point the VCR remote at the VCR and press the Play button on it to play the tape.
When you have finished with your presentation remove the tape from the VCR. Press the Eject button located on the front of the VCR to retrieve the tape.
Set the projector’s input source to the instructor’s computer. Point the Sharp remote at the projector and press the Input button until you see “INPUT 1” in the upper right corner of the screen.
Turn the projector off. Point the Sharp remote at the projector and press the Off button twice.
Raise the projection screen.
Put the Sharp remote and the VCR remote back into the computer cabinet.
Close and lock the computer cabinet door.

C. Using a Laptop for Audio/Video Presentations:

Lower the projection screen
Turn the laptop on.
Turn the ceiling-mounted projector on with the gray Sharp projector remote. The Sharp remote should be inside the computer cabinet. Point the Sharp remote at the ceiling mounted projector and press the On button. It will take up to 30 seconds for the projector to warm-up to full intensity.
Set the audio/video input source to the laptop computer. Switch the Main Computer/Laptop switchbox to “Laptop”. The Main Computer/Laptop switchbox is located on the bottom shelf inside the computer cabinet. Switch it to the “B” or “Laptop” position, if it is not already.
Set the projector’s input source to the instructor’s computer. Point the Sharp remote at the projector and press the Input button until you see “INPUT 1” in the upper right corner of the screen.
Connect the laptop audio and video cables to the laptop. These two cables should be coiled up on the bottom shelf of the computer cabinet. The laptop video cable has a semi-rectangular shaped end with nine pins. It fits onto the alternate video port on the back of the laptop. The alternate video port is also semi-rectangular shaped and has nine pinholes. The laptop audio cable has one round metal pin that fits into the headphone port of the laptop. Connect these two cables to the laptop.
Toggle the laptop’s video display mode if necessary. If the laptop has booted up completely and you do not see anything on the projection screen, then you may need to change the laptop’s video display mode. The three display modes are listed below.

Laptop Screen Only – The projector receives no video input from the laptop so the projection screen is blank, but the laptop’s monitor looks normal.
Laptop Screen and Alternate Video – The projector and the laptop’s monitor receive the same input so that you see the same image on the projection screen as on the monitor’s screen.
Alternate Video Only – The projector receives the video input from the laptop, but the laptop’s monitor does not. The laptop’s monitor screen is blank while the projection screen shows the normal video signal from the laptop.

All laptops have a key combination that toggles between the display modes. Usually the key combination is [Fn]+[F-key] where [Fn] is the Function key, [F-key] is one of the keys labeled “F1” through “F12”, and + means that you press both keys simultaneously. The appropriate F-key should be labeled with either two symbols that resemble monitors or with the letters “CRT/LCD”. It can take a couple of seconds for the display mode to change so pause before attempting to change the display mode again. You may have to change the display mode two or three times before you find the one you want. Some laptops may only have two of the display modes listed above.
When you are finished with your presentation set the audio/video input source to the instructor’s computer. Switch the Main Computer/Laptop switchbox to “Main Computer”. The Main Computer/Laptop switchbox is located on the bottom shelf inside the computer cabinet. Switch it to the “A” or “Main Computer” position.
Turn the projector off. Point the Sharp remote at the projector and press the Off button twice.
Disconnect the laptop audio and video cables from the laptop, coil them, and place them on the bottom shelf of the computer cabinet.
Raise the projection screen.
Put the Sharp remote back into the computer cabinet.
Close and lock the computer cabinet door.

D. Using the Lapel Microphone:

Unlock and open the computer cabinet.
Clip the belt pack and microphone to your clothes. The belt pack has a clip on the back for securing the belt pack to a belt or the waist of your clothes. You may also put the belt pack in your pocket. The microphone has a clip for securing it to your collar or lapel.
Turn the microphone on. The belt pack has two switches on top labeled “Power” and “Audio”. Put both of these switches in the On positions. You should see the red light between the switches come on briefly. This indicates a good battery. If the light stays on, then the battery is bad and needs to be replaced.
When you are finished using the microphone always turn it completely off. Put both the Power and Audio switches on the belt pack in the Off position. This will help preserve the battery.
