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.

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

v
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.
