Problems and Solutions 65 Problems Using an SD Card Certain images don't appear If you use your computer to copy images to the document camera's internal memory or an SD card, you need to make sure their format is correct: • Images must be DCF-compliant JPEG files to be displayed, such as from a digital camera. Avoid editing your images, as this may change their format and prevent them from being displayed. • Images must be named using the format ABCD1234.JPG, where ABCD is any combination of upper- or lowercase letters and 1234 is any combination of numbers. For example: Pict0001, Pict0002, etc. • Images must be placed in a folder named DCIM\123ABCDE, where 123 is any combination of numbers and ABCDE is any combination of upper- or lowercase letters. If this folder structure doesn't exist, first create a folder named DCIM, then create a folder within it with the desired name (for example, 100EPSON).

Problems Connecting a Laptop If you've connected a laptop computer (s p.21) but the image doesn't appear on the screen, check the following: • Windows: Hold down the Fn key and press the function key (such as or CRT/LCD) that lets you display on an external monitor. On most systems, the or CRT/LCD key lets you toggle between the LCD screen and the projector, or display on both at the same time. Check your monitor settings to make sure both the LCD screen and the external monitor port are enabled. From the Control Panel, open the Display utility. Click the Settings tab, then click Advanced. The method for adjusting the settings varies by brand; you may need to click a Monitor tab, then make sure the external monitor port is set as your primary display and/or enabled. See your computer's documentation or online help for details. • Mac OS X: From the Apple menu, select System Preferences, then click Display or Displays. Select VGA Display or Color LCD, click Arrangement or Arrange, and make sure Mirror Displays is checked.
