Ringer Equivalence Number
The Ringer Equivalence Number and FCC Registration Number for
this machine may be found on the label located on the bottom or
rear of the machine. In some instances you may need to provide
these numbers to the telephone company.
The Ringer Equivalence Number (REN) is a measure of the electrical
load placed on the telephone line, and is useful for determining
whether you have “overloaded” the line. Installing several types of
equipment on the same telephone line may result in problems
making and receiving telephone calls, especially ringing when your
line is called. The sum of all Ringer Equivalence Numbers of the
equipment on your telephone line should be less than five in order
to assure proper service from the telephone company. In some cases,
a sum of five may not be usable on your line. If any of your telephone
equipment is not operating properly, you should immediately
remove it from your telephone line, as it may cause harm to the
telephone network.
The equipment complies with Part 68 of the FCC rules and the
requirements adopted by the ACTA. On the rear of this equipment is
a label that contains, among other information, a product identifier
in the format US:AAAEQ##TXXXX. If requested, this number must be
provided to the telephone company.
FCC Regulations state that changes or modifications to this
equipment not expressly approved by the manufacturer
could void the user’s authority to operate this equipment. In
the event that terminal equipment causes harm to the
telephone network, the telephone company should notify
the customer that service may be stopped. However, where
prior notice is impractical, the company may temporarily
cease service, providing that they:
a promptly notify the customer.
b give the customer an opportunity to correct the
equipment problem.
c inform the customer of the right to bring a complaint to
the Federal Communication Commission pursuant to
procedures set out in FCC Rules and Regulations Subpart E
of Part 68.
You should also know that:
• Your machine is not designed to be connected to a digital PBX
system.
• If you intend to use a computer modem or fax modem on the
same phone line as your machine, you may experience
transmission and reception problems with all the equipment. It is
recommended that no other equipment, except for a regular
telephone, share the line with your machine.
