iv
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
v
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.
