Troubleshooting
■ For the included software
The driver cannot be installed.
• Is the USB cable connected correctly?
Check the USB cable connection. Disconnect the USB
cable, then connect it again.
• Is the USB function enabled on your computer?

first time, if the "Add New Hardware Wizard" does not
appear, the USB function on the computer may be dis-
abled. Perform the following steps.

Make sure that no "!" or "x" marks appear at "Universal
serial bus controller" or "USB Root Hub." If you see an
"!" or "x" mark, the USB controller is disabled.
• Is any unknown device registered?
If driver installation fails, the instrument will be marked
as an "Unknown device," and you will not be able to
install the driver. Delete the "Unknown device" by fol-
lowing the steps below.
