The built-in modem is built into the ThinkPad computer. It complies with
Part 68 of the FCC Rules. A label is affixed to the bottom of the computer
that contains, among other things, the FCC registration number, USOC,
and Ringer Equivalency Number (REN) for this equipment. If these
numbers are requested, look at the label and provide this information to
your telephone company.
3. 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 (5.0). To be certain of the number of devices you
may connect to your line, as determined by the REN (REN:0.7), you
should call your local telephone company to determine the maximum REN
for your calling area.
4. If the built-in modem causes harm to the telephone network, the telephone
company may discontinue your service temporarily. If possible, they will
notify you in advance. But, if advance notice isn’t practical, you will be
notified as soon as possible. You will be advised of your right to file a
complaint with the FCC.
5. Your telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect the proper operation of your
equipment. If they do, you will be given advance notice so as to give you
an opportunity to maintain uninterrupted service.

Authorized Seller, or the IBM Corporation, 500 Columbus Avenue,
Thornwood, NY 10594, 1-800-772-2227, for repair/warranty information.
The telephone company may ask you to disconnect this equipment from
the network until the problem has been corrected, or until you are sure the
equipment is not malfunctioning.
7. No customer repairs are possible to the modem. If you experience trouble
with this equipment, contact your Authorized Seller or the IBM
Corporation for information.
8. The modem may not be used on coin service provided by the telephone
company. Connection to party lines is subject to state tariffs. Contact your
state public utility commission or corporation commission for information.
