Installing and checking the USB driver

1. Turn on your computer and, if it’s not running 

already, start Windows 98/98SE or Windows 
Me.

2. Connect the power cord to a suitable AC outlet.

This unit can be on or in standby mode when 
installing the driver.

3. Connect this unit to a USB port on the com-

puter using the supplied USB cable.
Windows automatically detects this unit and 
installs the necessary driver software. Make opera-
tions as indicated in the dialog box. You may be 
requested to insert your Windows OS CD-ROM. 

* The installation may take a longer time depend-

ing on the system environment. After the instal-
lation dialog box disappears, wait several 
minutes.

Check that the USB driver has been installed success-
fully by following the procedure below.

“Settings”, and then “Control Panel”.

Audio Device” appears in the list, as shown.

* The screen image is for Windows 98SE.

* When using Windows Me, “?” may be shown at 

the head of “USB Copmposite Device” in green. 
This means the USB driver has been installed 
with the Generic ID supplied with the operating 
system. (This is not an error message.) 

9. Click the “+” symbol next to “Human Interface 

Devices”, and make sure that “HID-compliant 
consumer control device” and “USB Human

name, check the followings:

* The USB cable is firmly connected.
* The AC power cord of this unit is plugged into
