The Basics
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
fi ve (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 identifi er 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.
If you use more than one phone or other device on
the line, add up all of the RENs. If the total is more
than fi ve (three in rural areas), your telephones might
not ring. If ringer operation is impaired, remove a
device from the line.
In the unlikely event that your phone causes
problems on the phone line, the phone company
can temporarily discontinue your service. If this
happens, the phone company attempts to notify you
in advance. If advance notice is not practical, the
phone company notifi es you as soon as possible and
advises you of your right to fi le a complaint with the
FCC.
