The Page Up or Page Down buttons do not work on the remote control when I use the USB Display feature. What should I do?

• Change the USB TypeB setting in the projector's Extended menu to Wireless Mouse; This setting will load the software drivers for the feature on to your computer. After you've changed the setting, remember to return the setting to USB Display.

  Note: This feature is supported in Windows 2000, XP, Vista, 7 and 8; it's not supported on a Macintosh.
