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).
