FCC and IC Regulations
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 services in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility 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 electrical inspection authority, or electrician, as
appropriate.
Your VT 2431 is designed to operate at the maximum power allowed by the
FCC and IC. This means your Handset and Base Unit can communicate only
over a certain distance - which will depend on the location of the Base Unit and
Handset, weather, and the construction and layout of your home or office.
