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.
3. Facility Interface Information

through FCC Part 68 certified front-end host PBX equipment which specifies the type of

4. Disruption of the Network
If the Siemens optiPoint 500 telephone disrupts the telephone network, the telephone
company can discontinue your service temporarily. If possible, the telephone company will
notify you in advance. If advance notice is not practical, they will notify you as soon as pos-
sible. You are also informed of your right to file a complaint with the FCC.
5. Telephone Company Facility Changes

cedures that can affect the operation of your equipment. If they do, you should be notified
in advance so you have an opportunity to maintain uninterrupted telephone service.
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
magnetically coupled hearing aids. Persons who are not in common areas must also be
provided with hearing-aid compatible handsets, if needed.

68.316 Hearing Aid Compatibility and 68.317 volume control requirements.
7. Programmed Dialer Features
When you program emergency numbers or make test calls to emergency numbers using
Siemens products with programmed dialer features, stay on the line and briefly explain to
the dispatcher the reason for the call before hanging up. Perform these activities in off-peak
hours, such as early morning or late evening.
