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 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.

Additional Information
Modem model only.
Connection to party line service is subject to state tariffs. Contact the state public utility commission, public service
commission or corporation commission for information. Alarm dialing equipment must be able to seize the
telephone line and place a call in an emergency situation. It must be able to do this even if other equipment
(telephone, answering system, computer modem, etc.) already has the telephone line in use. To do so, alarm
dialing equipment must be connected to a properly installed RJ-31X jack that is electrically in series with and ahead
of all other equipment attached to the same telephone line. Proper installation is depicted in the figure below. If
you have any questions concerning these instructions, you should consult your telephone company or a qualified
installer about installing the RJ-31X jack and alarm dialing equipment for you.
