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 s 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.
• If your area experiences a high incidence of lightning or power surges, we
recommend that you install surge protectors for both the power and the
telephone lines. Surge protectors can be purchased from your dealer or
telephone and electronic specialty stores.
