9-4 Appendix
This equipment complies with Part 68 of the FCC rules. On the rear of this
equipment is a label that contains, among other information, the FCC
registration number and Ringer Equivalence Number (REN). If requested,
provide this information to your telephone company.
The REN is used to determine the quantity of devices you may connect to
your telephone line and still have all of those devices ring when your
number is called. In most, but not all areas, the sum of the RENs of all
devices should not exceed five (5.0). To be certain of the number of devices
you may connect to your line, as determined by the REN, you should call
your local telephone company to determine the maximum REN for your
calling area.
ASK your local telephone company for the modular jack type installed on
your line. Connecting this machine to an unauthorized jack can severely
damage telephone company equipment. You, not Xerox, assume all
responsibility and/or liability for any damage caused by the connection of
this machine to an unauthorized jack.
You may safely connect the machine to the following standard modular
jack: USOC RJ-11C. Use the standard line cord (provided with the
machine) to connect it.
An FCC compliant telephone cord and modular plug is provided with this
equipment. This equipment is designed to be connected to the telephone
network or premises wiring using a compatible modular jack which is Part
68 compliant.
Do not connect this machine to a party or coin operated phone line.
Repairs to the machine should be made only by a Xerox representative or an
authorized Xerox service agency. This applies at any time during or after
the service warranty period. If unauthorized repair is performed, the
remainder of the warranty period is null and void.
