and safety requirements as prescribed in the appropriate Terminal Equipment Technical
Requirements document(s). The Department does not guarantee the equipment will operate to the
user’s satisfaction.
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 come situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier.
Any repairs of 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 connection of the power
utility, telephone lines, and internal metallic water pipe system, if present, are connected together.
This precaution may be particularly important in rural areas.
