Before installing this equipment, users should ensure that it is permissible to be

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, telephone lines, and internal metallic water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.
