c) 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 de-
vices that may be connected to a line, as determined 
by the total RENs, contact the local telephone com-
pany. 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.

advised of your right to file a complaint with the 
FCC if you believe it is necessary.

e) The telephone company may make changes
