should not exceed five. To determine the number of devices you may connect
to the line, contact your local telephone company to find the maximum REN
for your calling area.
If your system causes harm to the telephone network, the telephone company
may discontinue service temporarily. If possible, they will notify you in
advance. If advance notification is not practical, you will be notified as soon
as possible.
Your telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect proper functioning of your
equipment. If they do, they should notify you in advance to give you an
opportunity to maintain uninterrupted telephone service.
You may not under any circumstances attempt any service, adjustments, or
repairs on the modem. It must be returned to the factory for any such work.
