2. REN
The ringer equivalence number (REN) is used to determine the quality 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). At the base of the telephone is a label contains,
among other information, the REN and the FCC certification number. If requested, this in-
formation must be given to the telephone company. To be certain of the number of devices
that may be connected to a line, as determined by the total RENs, contact the local tele-
phone company.
Note: REN is associated with the analog telephones. It is not applicable to Siemens opti-
Point 500 telephone. If requested, please supply the FCC Certification numbers of the
front-end host terminal equipment that have a direct Public Switched Telephone Network
connection (i.e. have a REN stated on the label) and the highest REN.

sible. You are also informed of your right to file a complaint with the FCC.

cedures that can affect the operation of your equipment. If they do, you should be notified

6. Hearing-Aid Compatibility
Telephones for emergency use and telephones installed in common areas such as lobbies,
hospital rooms, elevators, and hotel rooms must have handsets that are compatible with
