Federal Communications Commission (FCC) and telephone
company requirements
1. This device complies with Part 68 of the FCC rules. A label is affixed to the
device that contains, among other things, the FCC registration number,
USOC, and Ringer Equivalency Number (REN) for this equipment. If these
numbers are requested, provide this information to your telephone
company.
Nota: If the device is an internal modem, a second FCC registration label
is also provided. You may attach the label to the exterior of the computer in
which you install the Lenovo modem, or you may attach the label to the
external DAA, if you have one. Place the label in a location that is easily
accessible, should you need to provide the label information to the
telephone company.
2. The REN is useful to determine the quantity of devices you may connect to
your telephone line and still have those devices ring when your number is
called. In most, but not all areas, the sum of the RENs of all devices should
not exceed five (5). To be certain of the number of devices you may connect
to your line, as determined by the REN, you should call your local
telephone company to determine the maximum REN for your calling area.
