The Ringer Equivalence Number (or REN) is used to determine the number of devices that
may be connected to a telephone line. Excessive RENs on a telephone line may result in the
devices not ringing in response to an incoming call. In most but not all areas, the sum of RENs
should not exceed five (5.0). To be certain of the number of devices that may be connected to
a line, as determined by the total RENs, contact the local Telephone Company. For products
approved after July 23, 2001, the REN for this product is part of the product identifier that has
the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal
point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
