90 Solving Problems
You have lost the remote control.
You need the remote control to access many projector features. If you
have lost it, you can order another from Epson. See page 91 for details
about ordering.
You can’t control the mouse pointer with the remote
control.
■ Make sure the USB mouse cable is securely connected to both
your computer’s USB port and the projector’s USB port. For
details, see page 19.
■ To use the USB mouse connection on a PC, your system must
have a “clean” installation of Windows 98SE, Windows Me,
Windows XP, or Windows 2000. The connection may not work
correctly if your system was upgraded from Windows 95.
■ If you’re running Windows 98 or Me, you may need to install
USB drivers from your Windows CD-ROM. After you install the
drivers, restart both the computer and the projector to
resynchronize the setup.
■ You can’t use the wireless mouse function while using the
E-Zoom buttons on the remote, adjusting the volume, capturing
a user’s logo, or displaying a configuration or help menu.
