Interference
The Model 3120 generates and uses radio frequency energy, and if not installed and used properly—that is, in
strict accordance with the manufacturer's instructions—may cause interference to radio and television recep-
tion. The Model 3120 has been tested and found to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reason-
able protection from such interference in a commercial installation. However, there is no guarantee that inter-
ference will not occur in a particular installation. If the Model 3120 causes interference to radio or television
reception, which can be determined by disconnecting the cables, try to correct the interference by one or more
of the following measures: moving the computing equipment away from the receiver, re-orienting the receiving
antenna, and/or plugging the receiving equipment into a different AC outlet (such that the computing equip-
ment and receiver are on different branches).
Industry Canada Notice
The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and safety require-
ments. The Department does not guarantee the equipment will operate to the user's satisfaction. Before install-
ing 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 connec-
tion. In some cases, the company’s inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The customer should be
aware that compliance with the above condition may not prevent degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized 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 ground connections of the power utility, telephone lines and internal metallic
water pipe system, are connected together. This protection may be particularly important in rural areas.
