Rules. These limits are designed to provide reasonable protection

against harmful interference in a commercial environment. This

equipment generates, uses, and can radiate radio frequency energy,

and if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications.

If this equipment does cause harmful interference to radio/television

reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by

one or more of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and the receiver.

•Connect the equipment into an outlet on a circuit different from

that to which the receiver is connected.

•Consult the dealer or an experienced radio/TV technician for

help.

Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to

operate the equipment. Shielded RS-232 cables are required to be

used to ensure compliance with FCC Part 15, and it is the

responsibility of the user to provide and use shielded RS-232

cables.

Information for Canadian Users

The Industry Canada label identifies certified equipment. This

certification means that the equipment meets certain

telecommunications network protective, operation, and safety

requirements. The Industry Canada does not guarantee that the

equipment will operate to a 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. The customer should be aware that the compliance with

the above conditions may not prevent degradation of service 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.

For their own protection, users should ensure 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.

This digital apparatus does not exceed the class A limits for radio

noise emissions from digital apparatus set out in the radio

interference regulations of Industry Canada. The declarations of CE
