Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.
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 ensure for their own protection that the electrical ground connections of the power utility,

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
