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.
CP01, Issue 8, Part I Section 14.2

interface. The terminal on an interface may consist of any combination of devices subject only to the
requirement that the sum of the Ringer Equivalence Numbers of all the Devices does not exceed 5.
Hearing Aid Compatibility Notice: The FCC has established rules that require all installed business
telephones be hearing aid compatibile. This rule applies to all telephones regardless of the date of
manufacture or installation. There are severe financial penalties which may be levied on the end-user for
non-compliance.
