How do I switch the picture source between the camera image and a computer or laptop connected to the document camera?

• Using the Source button, you can easily switch back-and-forth between your computer and the camera image. Follow these steps to connect your computer or laptop:
  1. If you are using a desktop computer, disconnect the monitor cable from your computer.
  2. Connect a VGA cable from your computer's monitor-out port to the document camera'a VGA in port.
     
     Note: If the projector is connected using a VGA cable, you'll need a second VGA cable to connect the document camera to the computer.
     
  3. To display your computer's image (such as a PowerPoint presentation), press the Source button.
     
     To switch back to the live camera image, press the Source button again.
  If you've connected a laptop computer but the image doesn't appear on the screen, 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.
