NOTICE TO MODEM USERS IN THE USA
The 5601MSC Master Clock/Sync Generator complies with the FCC Rules Part 68. The 5601MSC is designed to
be used on standard device telephone lines. It connects to the telephone line by means of a standard jack called
the USOC RJ11C and should be connected to the telephone network with a FCC compliant telephone cord and
modular plug.
It is not necessary to notify the telephone company before connecting the modem in the 5601MSC. However, the
telephone company may request the telephone number to which the 5601MSC modem is connected and the FCC
registration number and ringer equivalence number (REN), both of which are on the label on the rear panel.
The REN is used to determine the number of devices you may legally connect to your telephone line. In most
areas, the sum of the REN of all devices connected to one line must not exceed five (5.0). You should contact
your telephone company to determine the maximum REN for your calling area.
The 5601MSC may not be used on coin service provided by the telephone company. Connection to party lines is
subject to state tariffs.
If the modem in the 5601MSC is malfunctioning, it may affect the telephone lines. In this case, disconnect the
modem until the source of the difficulty is traced.
