Notification of Local Telephone Company
On the bottom of this equipment is a label that contains, among
other information, a product identifier in the form
US:AAAEQ##TXXXX. You must, upon request, provide this
information to your telephone company.
The digits represented by ## in the product identifier indicate
the Ringer Equivalency Number (REN) for this equipment. The
REN is useful in determining the number of devices you may
connect to your telephone line and still have all of these
devices ring when your telephone number is called. In most
(but not all) areas, the sum of the RENs of all devices
connected to one line should not exceed 5. To be certain of the
number of devices you may connect to your line as determined
by the REN, contact your local telephone company.
