Ringer Equivalence No. (REN)
The 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 following
format:
• US:AAAEQ##TXXXX
The digits represented by ## are the REN without a decimal point (e.g., 03 is a REN of 0.3).
