Caution

• 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.
