Radio and Television Interference

This equipment generates and uses radio frequency energy and if not installed and used properly, in strict

accordance with the manufacturer's instructions, may cause interference to radio and television reception. The

modem has been tested and found to comply with the limits for a Class B computing device in accordance with the

specifications in Part 15 of FCC rules, which are designed to provide reasonable protection against such

interference in a residential installation. However, there is no guarantee that interference will not occur in a

particular installation.

If this device does cause interference to radio or television reception, which you can determine by monitoring

reception when the modem is installed and when it is removed from the computer, try to correct the problem with

one or more of the following measures:

Reorient the receiving antenna (for televisions with antenna reception only) or cable input device.

Relocate the computer with respect to the receiver.

Relocate the computer and/or the receiver so that they are on separate branch circuits.

If necessary, consult your dealer or an experienced radio/television technician for additional suggestions.

For Canadian Modem Users

NOTICE: The Industry Canada (IC) label identifies certified equipment. This certification means the equipment

meets certain telecommunications network protective, operational, and safety requirements as prescribed in the

appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the

equipment will operate to the user's satisfaction. 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. 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 conditions may not prevent

degradation of service in some situations.

Currently, telecommunication companies do not allow users to connect their equipment to jacks except in precise

situations that are spelled out in tariffing arrangements with those companies.

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.

For your own protection, make sure 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: Do NOT attempt to make such connections yourself. Instead contact the electric inspection authority or

electrician, as appropriate.

"NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the

maximum number of te rminals allowed to be connected to a telephone interface. The termination 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."

The Ringer Equivalence Number is located on the modem's circuit board.

For service and repair issues, contact your computer system manufacturer.
