• Plug the USB cable into the modem and Computer with
care. Forcing the cable in upside down may damage the
cable, modem, or USB port.
• Use the supplied USB cable or a certified USB 2.0
cable only when connecting the modem to a Computer.

Computer, the communication between the modem
and the Computer may be interrupted by noise that the
Computer emits.
