The ringer equivalence number (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). 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, 2002, the REN is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (i.e., 03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
If this VitalPoint Home Monitor causes harm to the telephone network, the telephone company will notify you in advance that temporary discontinuance of service may be required. But if advance notice isn’t practical, the telephone compa- ny will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it’s necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the VitalPoint Home Monitor. If this happens, the telephone company will provide advance notice in order for you to make necessary modifications to maintain uninterrupted service.
Connection to party line service is subject to state tariffs (U.S.). Contact the state public utility commission, public service commission, or corporation commission for information.
If installed in a home with specially wired alarm equipment connected to the telephone line, ensure the installation of the VitalPoint Home Monitor does not disable the alarm equipment. If you have questions about what will disable alarm equipment, consult the telephone company or qualified installer.
Electrical safety advisory: Parties responsible for equipment requiring AC power should consider including an advisory notice in their customer information suggest- ing the customer use a surge arrestor. Telephone companies report that electrical surges, typically lightning transients, are very destructive to customer terminal equipment connected to AC power sources. This has been identified as a major nationwide problem.
