Issued Mar-06 General Information 1-8
1.3 FCC Information
This equipment complies with Part 68 of the FCC rules. Etched on the
modem assembly is, among other information, the FCC certification
number and Ringer Equivalence Number (REN) for this equipment. If
requested, this information must be provided to the telephone company.
This module has an FCC-compliant telephone modular plug. The module
is designed to be connected to the telephone network or premises’ wiring
using a compatible modular jack that is Part 68-compliant.
The REN is used to determine the quantity of devices that 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.
Typically, the sum of the RENs should not exceed five (5.0). Contact the
local telephone company to determine the total number of devices that
may be connected to a line (as determined by the total RENs).
If this equipment and its dial-up modem causes harm to the telephone
network, the telephone company will notify you in advance that temporary
discontinuance of service may be required. However, if advance notice is
not practical, the telephone company will notify the customer as soon as
possible. In addition, you will be advised of your right to file a complaint
with the FCC if you believe it necessary.
The telephone company may make changes to its facilities, equipment,
operations, or procedures that could affect the operation of the equipment.
If this happens, the telephone company will provide advance notice so you
can make the necessary modifications to maintain uninterrupted service.
If you experience trouble with this equipment or the dial-up modem,
contact Emerson Process Management’s Flow Computer Division (at 641-
754-3923) for repair or warranty information. If the equipment harms the
telephone network, the telephone company may request that you
disconnect the equipment until the problem is resolved.
