Registration
The CO line telephone numbers, FCC registration number, and ringer equivalence number (REN) of this
equipment must be provided to the telephone company before installation. (See below for FCC registration
number and ringer equivalence number.)
FCC Part 15
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and — if not installed and used in accordance with the instruction
manual — may cause harmful interference to radio communications (in which case, the user will be required
to correct the interference at his/her own expense).
FCC Part 68
This equipment complies with Part 68 of the FCC Rules. On the bottom of this equipment is a label that
contains, among other information, the FCC Registration Number and Ringer Equivalence Number (REN) for
this equipment. You must, upon request, provide this information to your telephone company.
The REN is helpful to determine the quantity of devices you say connect to your telephone line and still have
all of those devices ring when your telephone number is called. In most, but not all, areas, the sum of the
RENs of all devices connected to one line should not exceed five (5.0). To be certain of the number of
devices you may connect to your line, as determined by the REN, you should contact your local telephone
company to determine the maximum REN for your calling area.
If your telephone equipment causes harm to the telephone network, the telephone company may discontinue
your service temporarily. If possible, the telephone company will notify you in advance but, if advance notice
is not practical, you will be notified as soon as possible. You will be informed of your right to file a complaint
with the FCC.
Your telephone company may make changes to its facilities, equipment, operations or procedures that could
affect the proper functioning of your equipment. If so, you will be notified in advance, to give you an
opportunity to maintain uninterrupted telephone service.
If you experience trouble with this telephone equipment, the telephone company may ask that you disconnect
this equipment from the network until the problem has been corrected or until you are sure that the equipment
is not malfunctioning.
This equipment may not be used on coin service provided by the telephone company. Connection to party
lines is subject to state tariffs.
