The default value of the administrator password is printed on the label on the product itself, such as the one shown.
If both labels (1) and (2) are attached, the value next to PASSWORD written on the label in (1) is the default value. In this example, the default value is 03212791.
As the label (1) is attached in a location that is difficult to see, check the information in the link to confirm the location.
If you cannot find the label (1), the serial number printed on the label in (2) is the default value. In this example, the default value is X3B8153559.
