Canadian Department of Communications Modem Connection Requirements
NOTE: The Canadian Department of Communications label identifies certified equipment.
This certification means that the equipment meets certain telecommunications network
protective, operational and safety requirements. 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.
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.
Users should ensure for their own protection 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.
WARNING: Users should not attempt to make such connections themselves, but should
contact the appropriate inspection authority or electrician.
The Load Number (LN) assigned to each terminal device denotes the percentage of the
total load to be connected to a telephone loop which is used by the device, to prevent
overloading. The termination on a loop may consist of any combination of devices subject
only to the requirement that the total of the Load Numbers of all the devices does not
exceed 100.
BATTERY REPLACEMENT
A lithium battery in your computer maintains system configuration information. In the event
that the battery fails to maintain system configuration information, NEC CSD recommends
that you replace the battery (see Section 4, "Maintenance and Troubleshooting," for battery
removal procedures).
WARNING: There is a danger of explosion if the battery is incorrectly replaced. Replace
only with the same or equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer's instructions.
ATTENTION: Il y a danger d'explosion s'il y a replacement incorrect de la batterie.
Remplacer uniquement avec une batterie du même type ou d'un type recommandé par le
constructeur. Mettre au rébut les batteries usagées conformément aux instructions du
fabricant.
