Notice to Users of the Telephone Network
This equipment complies with Part 68 of the FCC rules. On the inside of the
equipment’s enclosure is a label that contains, among other information, the FCC
registration number and ringer equivalence number (REN) for this equipment. If
requested, this information must be provided to the telephone company.
This equipment is intended to be hard wired to the telephone line’s primary protector
and to the inside building wiring. If the primary protector utilizes an RJ11C jack for the
inside building wiring connection, connection to the protector must be made using a
Part 68-compliant telephone line cord, spade terminal to RJ11C plug.
The REN is used to determine the quantity of devices which may be connected to the
telephone line. Excessive RENs on the 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 (5.0). 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.
