Repairs to certified equipment should be coordinated by a representative designated by the supplier.
Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the equipment.
Users should make sure for their own protection that the electrical ground connections of the power
utility, telephone lines and internal metallic water pipe systems, if present, are connected together.
This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the
maximum number of terminals allowed to be connected to a telephone interface. The termination on
an interface may consist of any combination of devices subject only to the requirement that the sum
of the Ringer Equivalent Numbers of all of the devices does not exceed 5. For the Canadian REN value,
please see the label on the equipment.
Europe
Radio Equipment & Telecommunications Terminal Equipment Directive
The Facsimile has been approved in accordance with the Council Decision 1999/5/EC for pan-European
single terminal connection to the public switched telephone network (PSTN). However, due to
differences between the individual PSTNs provided in different countries, the approval does not, of
itself, give an unconditional assurance of successful operation on every PSTN network terminal point.
In the event of a problem you should contact your authorized local dealer in the first instance.
This product has been tested to and is compliant with ES 203 021-1, -2, -3, a specification for terminal

product provides an user-adjustable setting of the country code. Refer to the customer documentation

recommended that it is set to use DTMF signaling. DTMF signaling provides reliable and faster call
setup. Modification of this product, connection to external control software or to external control
apparatus not authorized by Xerox, will invalidate its certification.
