• Some computers may have multiple display screen modes. Use of some of these modes
will not be possible with this projector.
• Be sure to check jack type, signal level, timing and resolution before connecting this
projector to a computer.
• Depending on the input signal, full-size display may not be possible in some cases. Refer
to the number of display pixels above.

Connecting the USB
1. Connect the projector and computer with a suitable commercially available cable.
2. Press the INPUT button of the projector or the RGB 1/2 button of the remote control and select
the input where the computer is to be connected.
3. Start the mouse function.
4. Refer to page 10, 26 concerning the remote control of mouse operations.
5. The movement speed of the mouse varies according to time to push button.
6. The left click of the mouse can manipulate the right click of the MENUSELECT button, the
mouse with the RESET button.

• Before making connections, read the instruction manual of the equipment to be
connected.
• Use the optional USB cable to connect.
• Effective with USB only when the mouse is used.
• Do not use with any device other than a personal computer.
• When using with Windows 95, it is necessary to set so that USB can be used with
version OSR 2.1 or higher. Depending on the kind or the virsion of the host controller,
operation may not be possible in some cases.
• In the case of notebook type computers with a built-in pointing device such as a track
ball, in some cases the built-in pointing device will have priority even if a mouse is
connected and the mouse may not be selected.
In such case, disable the built-in pointing device and change the BIOS setting (system
setup) so that an external mouse can be selected.
After changing the BIOS setting, perform the operations described in 1 - 3 above.
Refer to the computer hardware manual concerning the BIOS setting.
Also, some computers may not have a utility program to operate a mouse. Refer to the
computer hardware manual.
