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. Caution:
Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or
electrician, as appropriate
。
