DC-10s Document Camera

Selected FAQ

Q:
Nothing is projected on the screen. What should I do?
A:
Try the following:

  • After you press the  Power button, wait a few moments for the image to appear. It takes about 10 seconds for the document camera to output an image.


  • Select the correct source on your projector or video display device. The source is the port to which you’ve connected the video cable. If you’re using a VGA cable, the source may be called something like “Computer” or “PC”.


  • If you’ve connected a computer, make sure to connect both the computer and projector to the document camera using VGA cables (one is included). Connect one cable from your computer to the document camera, and the other cable from the document camera to your projector or video display device.

    You cannot display computer images through the document camera’s S-video port.


  • If you’ve connected a computer, press the Source button on the document camera to switch between the live camera image and the image from your computer.


  • Make sure your projector or video display device is turned on and not in sleep mode. Make sure its picture has not been “muted” or turned off.


  • Make sure your cable(s) are connected correctly. See Connect the Document Camera.


  • If you’ve connected a laptop computer, make sure it’s set to display on an external monitor.


  • If you’re using a PC notebook:

    • Press the function key that lets you display on an external monitor. It’s often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while pressing it. Check your laptop’s manual or online help.

      On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time. Allow a few seconds for the projector to sync up after pressing it.


    • If the function key doesn’t let you display simultaneously on both screens, you might need to use the Display utility in the Windows Control Panel to make sure that both the LCD screen and external monitor port are enabled. From the Windows Control Panel, open the Display utility. In the Display Properties dialog box, click the Settings tab, then click Advanced. The method for adjusting the setting varies from computer to computer; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display or enabled. See your computer manual or online help for details.


    If you’re using Macintosh OS X:

    1. Select System Preferences from the Apple menu and click Displays.


    2. Click Detect Displays.


    3. To display the entire desktop on both your projector screen and LCD screen, click the Arrangement or Arrange tab. (If you don’t see this tab, make sure it isn’t hidden by another window.)


    4. Click Mirror Displays in the lower corner of the screen. One of the monitor icons automatically moves on top of the other.
