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.
WARNING:
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.
• When programming emergency numbers and/or making test calls to emergency
numbers, use a non-emergency number to advise the emergency service
dispatcher of your intentions. The dispatcher will give you further instructions on
how to actually test the emergency number.
